The "Editor-in-Chief Investigation" column team interviewed Qitai Sensing Chairman Wang Guoqiu and told the audience: How did Changsha build my country's first mass production line of metal-based pressure-sensitive chips?

Editor's Note

The third volume of "Xi Jinping on State Governance", "Strive to Become the World's Major Science Center and Innovation Highland", pointed out that "the key core technology is not available, can not be bought, and can not be bought. Only the key core technology is controlled by oneself. Only by holding hands can we fundamentally guarantee national economic security, national defense security, and other security." Since July 21 this year, General Secretary Xi Jinping has presided over the conferences of entrepreneurs, experts in economic and social fields, and scientists, all of which mentioned Breakthrough in "key core technology".

The key core technology is the key element for the development of an enterprise. If you master the key core technology, today's "little giant" may develop into tomorrow's "hulk". Starting from this issue, the "Editor-in-Chief Survey" launched a series of surveys "How are the key core technologies refined?", focusing on the invisible champions, small giant enterprises and unicorns in the field of "three wisdom and one core" (intelligent manufacturing) in Changsha Enterprises, visit entrepreneurs to lead the team to overcome difficulties, build key core technologies, and break foreign monopolies. The first issue of "How did Changsha build my country's first mass production line for metal-based pressure-sensitive chips?" was launched today.

Wang Guoqiu, born in Yueyang, Hunan, graduated from the Department of Mathematics, Hunan Normal University in 1983; graduated from the Department of Systems Engineering, National University of Defense Technology in 1988, with a Master of Engineering degree. For entrepreneurs who industrialize high-end chips. From the establishment of Hunan Qitai Sensing Technology Co., Ltd. in 2006, to the completion of my country’s only metal-based pressure-sensitive chip mass production line in 2019, Wang Guoqiu has used more than ten years of painstaking research to completely change my country’s long-term commitment to high-end pressure-sensitive chips. Dependent on imports.

small "buttons" big dreams

Driving more than 40 kilometers from Changsha to the east along Hangzhou-Changzhou Expressway, you will arrive at the national industrial park-Liuyang Economic Development Zone (High-tech Zone), where Hunan Qitai Sensing Technology Co., Ltd. founded by Professor Wang Guoqiu is located. In this cluster of industrial enterprises, the sign of "Qitai Sensor Internet of Things Industrial Park" is calm and low-key. The few clear gray buildings with ordinary appearances are the office buildings and factories of the industrial park. There are few employees in the park, which makes them feel particularly refreshed.

has the dual identities of university professor and entrepreneur, but Wang Guoqiu prefers everyone to call him Mr. Wang in the company, because in his opinion, the main task of professors is to "produce" knowledge, and entrepreneurs are responsible for converting knowledge into productivity. Under the leadership of Mr. Wang, the reporter walked into the factory building and discovered that there was a magical space inside. From more than 10 unattended auxiliary facilities on the first floor, to the 2000-square-meter "ultra-clean workshop" on the second floor, to the packaging and testing workshop on the third floor, most of the company's production lines are automated. This high-tech enterprise with an annual output value of more than 500 million yuan, currently all employees add up to less than 70 people.

In the workshop on the third floor, the reporter saw small metal "buttons" waiting to be encapsulated. Mr. Wang said that if you put it under a microscope with a magnification of 100 times, you can see densely packed and extremely complicated circuits. Different from the common square black chip, this special button type chip is called a metal-based pressure-sensitive chip. Its function is to complete force signal acquisition. It is the first pass of the information industry. The signal acquisition piece is called a sensor-sensitive chip.

Then, why did Wang Guoqiu, who was originally a university professor, transition to the field of sensor chip research and development?

Time has to go back to 2000. Wang Guoqiu, who has studied in the fields of mathematics and computer science, found that my country has a very weak foundation in integrated circuits and micro-electromechanical systems (MEMS), at least lagging behind developed countries such as the United States, Japan, and Germany for at least 30 years. At that time, foundry was more popular in the domestic manufacturing industry, but the core technology could not be replaced by foundry. Wang Guoqiu is keenly aware that if we do not master our own core technology, not only the manufacturing industry, but many other industries will be constrained by the key technical problems of "stuck necks".

It was also in 2000 that the state issued a series of policies to support the development of the integrated circuit industry. Time is not waiting, Wang Guoqiu seized this rare opportunity in time and founded a digital technology company called "SMIC". In 2003, the company developed my country's first digital image and video compression encoding and decoding chip with completely original independent intellectual property rights, which contributed to solving the high patent fees of DVD decoding chips at that time.

In 2006, Wang Guoqiu, who had a forward-looking vision in the field of chip research, aimed at metal-based pressure-sensitive chips in industrial applications and invested 2 million yuan to establish Hunan Qitai Sensing Technology Co., Ltd.

After ten years of hard work and more than ten years of painstaking research, in 2019, Qitai company built the only metal-based pressure-sensitive chip mass production line in China, which completely changed my country’s long-term dependence on high-end metal-based pressure-sensitive chips. .

Glossary: ​​pressure sensitive chip

A "button-type" pressure-sensitive chip with a diameter of no more than five or six millimeters can accurately convert pressure data into electronic signals and transmit them to the receiving processing terminal. It can be widely used in construction machinery, rail transit, automobiles, firefighting, and smart cities. , Petrochemical and other fields. Take the excavator as an example. According to different models and sizes, each excavator needs three to a dozen hydraulic sensors, and each hydraulic sensor needs a pressure-sensitive chip. For a long time, the market for such core technologies and high-end sensors has been basically occupied by companies in the United States, Japan, and Europe.

Wang Guoqiu told reporters that "SMIC" actually refers to "China Core", and the English name of "Qitai" is CHNTEK, which is the English abbreviation of "Chinese technology", and the Chinese homonym is "Qitai".

Whether it is "SMIC" or "Qitai", a small chip embodies Wang Guoqiu's family and country feelings, and is the great dream of a scholar-type entrepreneur who is obsessed with "China Chip".

The "chip dream" that I want to give up a hundred times

Behind every dazzling success, there is an unknown hardship. In 2019, Wang Guoqiu's success made the long-standing monopoly of my country's metal-based pressure-sensitive chips begin to melt away, but there are too many sorrows and sorrows behind the success.

Facing various difficulties, Wang Guoqiu said frankly that he also had a moment of near collapse, but he never really wanted to give up in his heart. China's core, in terms of product price and quality, compete with foreign countries" goal. With his enthusiasm and the Hunanese "endure, domination, and patience", Wang Guoqiu finally persevered.

Wang Guoqiu told reporters that the earliest fund of the company was all his personal contributions, and he had no other additional income that year, that is, he used his salary as a professor and his own lecture fees to support the experiment. Of course, he has also received a lot of support from the society. For example, the National University of Defense Technology, the former Shaoguang Microelectronics General Factory, etc., have not received any money to support him to do related experiments.

In Wang Guoqiu's memory, the difficulties encountered in the development process are really countless. For example, most chips are based on silicon to make circuits, but like the pressure-sensitive chips they developed are based on metal substrates to make circuits, then the mature so-called silicon process cannot be applied to this chip. When it comes to chips, from materials, equipment, design, manufacturing process, testing, and packaging, all things in this industry chain must be explored from scratch by the company. Wang Guoqiu said that since 2006, he started to make this type of button pressure-sensitive chip. For 15 years, the waste materials were counted as baskets. He couldn't remember exactly how many baskets there were.

  

 

The picture shows the production workshop of Hunan Qitai Sensing Technology Co., Ltd.

What Qitai does is the entire industrial chain of chip production. As long as there is a mistake in one link in the chain, it will cause all the games to be lost. But why does Wang Guoqiu pick a metal-based pressure-sensitive chip such a super difficult bone to harden it? Gnaw?

Wang Guoqiu said with a smile, the ignorant are fearless. At first, I didn't expect the difficulty to be so great at first to do this. It was just that it became harder and harder to do it later. It was more difficult to pass one level after another.

Buying materials, buying equipment, and doing experiments, Wang Guoqiu's personal investment of 2 million yuan soon disappeared, and he owed a lot of debts, and even people came to collect debts during the Chinese New Year. Fortunately, in 2013, after 7 years of technical research, the "fortress" of the key technology of metal-based pressure-sensitive chips was finally overcome.

Wang Guoqiu told reporters that in the most difficult time, he really thought about giving up a hundred times, but picked it up again after two days. Because it is really hard to give up, this life seems to have been destined to have an inscrutable relationship with this little chip. He has always believed that no matter how many ditches and hurdles are, if you bravely cross over, you will reach the other side of your dreams.

At present, Qitai’s core technology is completely independent and controllable. The production process and production line are 100% independently researched and developed. Key auxiliary materials such as substrates, targets and photoresist have been fully localized. The main equipment such as needle table realizes domestic customization. In a word, in the field of metal-based pressure-sensitive chips, foreign countries can no longer hold China's neck.

  

 

  The picture shows the production line of Hunan Qitai Sensing Technology Co., Ltd.

 

The development of pressure-sensitive chips not only has to overcome innumerable technical difficulties, Wang Guoqiu also has to face all kinds of huge temptations to make "quick money". In 2006, many people were keen to do so-called fast-money businesses such as finance, the Internet, stocks, and real estate. Wang Guoqiu is an expert and professor in mathematics and computer science. If you set foot in these industries, you will definitely make a lot of money. Lots of opportunities. However, Wang Guoqiu devoted all his attention to the development of pressure-sensitive chips. The stock did not open an account, nor did he invest in a house. In his opinion, there must always be some people who do research and development in core technologies and overcome difficulties.

Wang Guoqiu said that this may be inseparable from his army complex. When working in military academies, he witnessed a large number of top experts and professors settled in poverty and insisted on doing core technology research and development. Although he felt that the hope of industrialization at that time was not great, they have been doing so because of their responsibility and responsibility for independent innovation. Perseverance, it is the perseverance of this group of scientific research experts that deeply infected and inspired him to go on the road of independent chip research and development without hesitation.

Qitai has the best "salesman"

On July 21st, Du Jiahao, Secretary of the Hunan Provincial Party Committee, came to Qitai Company for investigation. He watched and told Wang Guoqiu from time to time that he must always adhere to innovation and leadership, focus on conquering a batch of core technologies and key materials, and continuously improve product quality and The core competitiveness of enterprises can better meet market demand. Relying on the leading enterprises in Hunan's construction machinery, automobile and other industries, actively promote upstream and downstream cooperation in the industrial chain, and help enterprises to better explore the market while improving the level of localization.

The reporter learned from the Changsha Municipal Bureau of Industry and Information Technology that the scale of Changsha's construction machinery industry is the largest in the country, but key components such as hydraulic sensors have long been dependent on imports. A piece of construction machinery is expensive, ranging from hundreds of thousands to millions. However, no matter how large the body is, the precise conduction of the small hydraulic sensor cannot be separated. The hydraulic sensor assembly line independently developed by Hunan Qitai Sensing Technology Co., Ltd. has already begun mass production, which is expected to completely meet the needs of Changsha and even the national construction machinery industry for supporting hydraulic sensors.

Wang Guoqiu confidently said: "The annual demand for hydraulic sensors in Hunan construction machinery is 600,000. After the company's assembly line equipment reaches production, the annual production capacity is 2 million, which can completely realize local matching."

Qitai’s core technology has been industrialized, but how to better develop the market is still a key issue facing Wang Guoqiu.

Wang Guoqiu found that although on the one hand we often call for our own core technology, on the other hand, after the core technology of independent innovation comes out, domestic users still don't recognize these core technologies. How to make the market accept these core technologies of independent innovation faster? Wang Guoqiu has been constantly exploring, and he was deeply moved by the proactive actions of various government departments in Hunan and Changsha. Wang Guoqiu said that under the direct concern of Hu Henghua, member of the Standing Committee of the Provincial Party Committee and Secretary of the Changsha Municipal Party Committee, the Changsha Municipal Bureau of Industry and Information Technology has done a lot of meticulous work for Qitai Company to guide upstream and downstream enterprises to connect and to guide the synchronous development of main engine parts factories.

Wang Guoqiu has his own set of plans for how companies can participate in international competition. He drew a very vivid analogy. Now the international market is mainly divided by the United States, Germany, Japan, Britain, and Switzerland. Others are on the strategic high ground. If you want to compete with others, then you must have innovative thinking. . Qitai's slogan is: Improve quality and competition! Under the premise of better quality, the price should be better. Let consumers consciously and truly accept these products from their hearts, and such an industry can be considered a success.

Company development blueprint

The first step: to refine the pressure-sensitive chip to achieve quality improvement;

Step 2: Strive to be listed on the Sci-Tech version around 2023, and expand the range of sensors to include temperature sensors, humidity sensors, displacement sensors, angle sensors, etc., and strive to become a bright business card in China's intelligent field.

In recent years, Changsha has vigorously promoted the high-quality development of the manufacturing industry, focusing on the introduction and implementation of projects around the "three wisdom and one core". Especially the chip, as a key core technology, is known as the "industrial food" of a country. Although the chip industry in Changsha started late, relying on independent research and development, related products in the field of chips made in Changsha are constantly breaking through and filling the domestic gap. In recent years, Changsha has made a comprehensive layout in chip design, manufacturing, packaging and testing and other fields, forming an industrial cluster. This year, the Changsha BYD Semiconductor new energy vehicle project with a total investment of 1 billion yuan was launched in the Changsha Economic Development Zone. It will build a production line with an annual output of 250,000 8-inch new energy automotive electronic chips, effectively solving the "stuck neck" of the core electronic power devices of new energy vehicles. "problem.

Data show that in the first half of this year, the output value of Changsha's new-generation semiconductor and integrated circuit industry chain enterprises above designated size increased by 21% year-on-year, and some companies such as Great Wall Galaxy and Kewei both increased by more than 190% year-on-year.

As an entrepreneur who has personally experienced and witnessed the rapid development of Changsha's manufacturing industry, Wang Guoqiu and his team have always been unswervingly moving forward on the road of independent innovation of core technologies.

This is a great era, this is the era where every struggling person can dream come true.

The future is here, the stars and the sea, and the pace of dream chasers will never stop.

A piece of construction machinery is expensive, ranging from hundreds of thousands to millions. However, no matter how large the body is, the precise conduction of the small hydraulic sensor cannot be separated. The hydraulic sensor assembly line independently developed by Hunan Qitai Sensing Technology Co., Ltd. has already begun mass production, which is expected to completely meet the needs of Changsha and even the national construction machinery industry for supporting hydraulic sensors.

Wang Guoqiu confidently said: "The annual demand for hydraulic sensors in Hunan construction machinery is 600,000. After the company's assembly line equipment reaches production, the annual production capacity is 2 million, which can completely realize local matching."

Qitai’s core technology has been industrialized, but how to better develop the market is still a key issue facing Wang Guoqiu.

Wang Guoqiu found that although on the one hand we often call for our own core technology, on the other hand, after the core technology of independent innovation comes out, domestic users still don't recognize these core technologies. How to make the market accept these core technologies of independent innovation faster? Wang Guoqiu has been constantly exploring, and he was deeply moved by the proactive actions of various government departments in Hunan and Changsha. Wang Guoqiu said that under the direct concern of Hu Henghua, member of the Standing Committee of the Provincial Party Committee and Secretary of the Changsha Municipal Party Committee, the Changsha Municipal Bureau of Industry and Information Technology has done a lot of meticulous work for Qitai Company to guide upstream and downstream enterprises to connect and to guide the synchronous development of main engine parts factories.

Wang Guoqiu has his own set of plans for how companies can participate in international competition. He drew a very vivid analogy. Now the international market is mainly divided by the United States, Germany, Japan, Britain, and Switzerland. Others are on the strategic high ground. If you want to compete with others, then you must have innovative thinking. . Qitai's slogan is: Improve quality and competition! Under the premise of better quality, the price should be better. Let consumers consciously and truly accept these products from their hearts, and such an industry can be considered a success.

Company development blueprint

The first step: to refine the pressure-sensitive chip to achieve quality improvement;

Step 2: Strive to be listed on the Sci-Tech version around 2023, and expand the range of sensors to include temperature sensors, humidity sensors, displacement sensors, angle sensors, etc., and strive to become a bright business card in China's intelligent field.

In recent years, Changsha has vigorously promoted the high-quality development of the manufacturing industry, focusing on the introduction and implementation of projects around the "three wisdom and one core". Especially the chip, as a key core technology, is known as the "industrial food" of a country. Although the chip industry in Changsha started late, relying on independent research and development, related products in the field of chips made in Changsha are constantly breaking through and filling the domestic gap. In recent years, Changsha has made a comprehensive layout in chip design, manufacturing, packaging and testing and other fields, forming an industrial cluster. This year, the Changsha BYD Semiconductor new energy vehicle project with a total investment of 1 billion yuan was launched in the Changsha Economic Development Zone. It will build a production line with an annual output of 250,000 8-inch new energy automotive electronic chips, effectively solving the "stuck neck" of the core electronic power devices of new energy vehicles. "problem.

Data show that in the first half of this year, the output value of Changsha's new-generation semiconductor and integrated circuit industry chain enterprises above designated size increased by 21% year-on-year, and some companies such as Great Wall Galaxy and Kewei both increased by more than 190% year-on-year.

As an entrepreneur who has personally experienced and witnessed the rapid development of Changsha's manufacturing industry, Wang Guoqiu and his team have always been unswervingly moving forward on the road of independent innovation of core technologies.

This is a great era, this is the era where every struggling person can dream come true.

The future is here, the stars and the sea, and the pace of dream chasers will never stop.
