Wang Guoqiu works in the office. At present, Qitai is planning to expand its production capacity and accelerate its development with the goal of listing.

At the booth of Hunan Qitai Sensing Technology Co., Ltd. in the exhibition area of ​​the 2020 Changsha Cybersecurity and Intelligent Manufacturing Conference, two elderly people came.

These are two old engineers. It turned out that before the start, the phone calls of the two elders reached Qitai Sensing. One of the engineers, Wu Lao, said that he began research in related fields in the 1990s. He heard that Qitai had achieved mass production, and he must insist on visiting the exhibits on site. I heard that a domestic chip cost more than 10,000 yuan in the early days, and now the market price is less than 200 yuan after production through the assembly line. Wu Lao first said that he did not believe anything, and then gave a thumbs up to the new generation of scientific researchers.

After many days, telling this story, Qitai Sensing chairman and general manager Wang Guoqiu is still very excited. He said: "From a professor of mathematics to the chairman of the company, what I have been thinking about over the years is to lead the team so that Hunan has more say in the sensing industry."

Character story

Changsha successfully rolled off the first batch of domestic metal-based pressure-sensitive chips

According to data from the China Academy of Information and Communications Technology, my country's sensor market has maintained rapid growth in recent years, and has maintained a double-digit growth rate in the past five years.

But unfortunately, due to the late start of domestic chip technology, the market for sensor sensitive chips is almost monopolized by foreign companies, which also causes domestic manufacturers to pay a lot of money for purchasing chips every year. However, there are also many companies that have successfully broken the monopoly and achieved good results in the field of sensor chips. Qitai Sensing is one of them.

The auxiliary facilities on the first floor of Qitai Sensing are all unattended, and there are only a few engineers monitoring data in the 2000 square meter "ultra-clean workshop" on the second floor. The production line has more than 40 production links, and most of the processes are automated.

It is understood that the production line of Qitai Sensing is a high-start micromechanical and microelectronic system production line. From materials, equipment, process technology, manufacturing process, testing to packaging, it can be completed independently, avoiding foreign technology, enterprises or Dependence on equipment and materials.

Today, Qitai sensing technology is 100% independently researched and developed, and the process is 100% independently researched. The core equipment such as lithography machine is jointly developed with domestic manufacturers, and the auxiliary materials such as substrate, target and photoresist are jointly developed with domestic manufacturers. . Qitai Sensing has almost established a complete industrial ecosystem.

Yes, Qitai Sensing is well-known in the sensor industry-its scientific research team has overcome the key technology of heterogeneous film formation, developed a full set of production processes, customized 90% of the production equipment, and established the only factory-scale production of metal The base pressure-sensitive chip production line has fully implemented domestic substitution at the industrial level. Products are widely used in aerospace, rail transit, construction machinery, automotive industry, smart cities and other fields. And 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.

As an entrepreneur who has personally experienced and witnessed the rapid development of Changsha's manufacturing industry, Qitai Sensing Chairman and General Manager Wang Guoqiu and his team have always been advancing courageously on the road of independent innovation of core technologies.

Wang Guoqiu, born in 1963, was born in Yueyang, Hunan. He 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's degree in engineering. He is a professor and doctoral supervisor in the School of Mathematics and Statistics of Hunan Normal University. , And at the same time an entrepreneur who is committed to industrializing high-end chips. From the establishment of Qitai Sensing in 2006 to the completion of my country’s only metal-based pressure-sensitive chip mass production line in 2019, he used more than ten years of painstaking research to realize the large-scale industrialization of high-end sensor chips with China’s independent intellectual property rights for the first time. Its technology has reached the world's advanced level, and its price has certain advantages compared with imported products. It fills the gap in domestic production lines and breaks the foreign blockade of my country's high-end pressure sensor metal-based chip technology.

Wang Guoqiu is an early developer of "China Chip" and has presided over 4 national-level integrated circuit projects. In 2006, Wang Guoqiu's research focus shifted to widely used pressure-sensitive chips and decided to take the road of industrialization. However, the development of pressure-sensitive chips is far more difficult than Wang Guoqiu expected. Wang Guoqiu's experiments are countless, and the "button-type" base material was burnt out from basket to basket.

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 2016, after a full 10 years of technical research, the "fortress" of the key technology of metal-based pressure-sensitive chips was overcome. In 2019, Qitai Sensing finally broke the core technology monopoly of European, American and Japanese companies, and successfully rolled off the first batch of domestic metal-based pressure-sensitive chips in Changsha, which can be widely used in smart cities, transportation rail vehicles, and construction machinery.

Facing a wide range of application fields and broad market prospects, Qitai Sensing is planning to expand its production capacity and aiming at the goal of listing to accelerate its development. The company's B round of financing has also begun.

Industrial Development

After reaching production, an annual output of 30 million pressure-sensitive chips

Hunan Qitai Information Technology Co., Ltd. was established in March 2006, settled in Liuyang Economic Development Zone (High-tech Zone) in November 2015, and changed the establishment of Hunan Qitai Sensing Technology Co., Ltd. Qitai Sensor Internet of Things Industrial Park started construction in 2016, covering an area of ​​100 acres with a total investment of 1 billion yuan.

“As a chip practitioner, I don’t want to be caught by anyone at any point. We are the only factory-built metal-based pressure-sensitive chip production line in China. We hope that in the next 3 to 5 years, Qitai will have an international presence. Strong competitiveness has changed the face of China’s sensor industry that is neither large nor strong." Wang Guoqiu said, "In 2025, we hope that my country’s industrial intelligence level will lead the world, and our “China Core” will become a part of industrial development. business card."

At present, Qitai Sensing is planning a second metal-based pressure-sensitive chip production line specifically developed for the automotive industry. After the production line is completed, it will produce 30 million pressure-sensitive chips per year, and the production level will reach the industry 4.0 standard.

High-end dialogue

Strive to become a beautiful business card in China's intelligent field

Q: Tell me about your ups and downs in developing and manufacturing sensor chips over the years.

Wang Guoqiu: I founded a digital technology company in 2000. 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, I aimed at metal-based pressure-sensitive chips in industrial applications and invested 2 million yuan to establish Hunan Qitai Sensing Technology Co., Ltd.

The difficulties encountered in the research and development process are really numerous. For example, most chips are based on silicon to make circuits, but the pressure-sensitive chips we developed are based on metal substrates to make circuits. Mature silicon technology cannot be applied to this chip. From materials, equipment, design, manufacturing process, testing, packaging, all things in this industry chain must be explored from scratch by the company. Since 2006, we have been making this type of button pressure-sensitive chip. For 15 years, the waste materials are counted as baskets. I don't remember exactly how many baskets there are.

In the hardest time, I thought about giving up a hundred times, but I picked it up again two days later. Because it is really hard to give up, this life seems to have been destined to have an inexplicable relationship with this little chip.

Q: The company’s core technology has already been industrialized, how to better develop the market in the next step?

Wang Guoqiu: The hydraulic sensor assembly line independently developed by the company has now begun mass production, which is expected to completely solve the hydraulic sensor supporting needs of Changsha and the national construction machinery industry. Because we have calculated that the annual demand for hydraulic sensors in Hunan construction machinery is 600,000, and the company's assembly line equipment will have an annual production capacity of 2 million after it reaches full capacity, which can fully realize local matching.

Indeed, 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 more quickly is something my team and I have been constantly exploring.

At the same time, I would also like to thank the government departments at all levels for their active actions. The industry and information departments and related industry chain offices have also taken the initiative to provide door-to-door services to carry out investigations on talent needs, supporting facilities for upstream and downstream enterprises, and development difficulties, and guide upstream and downstream enterprises to connect. Guide OEM parts factories to develop synchronously with each other, and do a lot of meticulous work to help enterprises become bigger and stronger.

Now, the slogan that Qitai puts forward is: Improve quality and competition-Under the premise of better quality, the price should be better. Only by allowing consumers to consciously and truly accept these products from their hearts can such an industry be considered a success.

I formulated a blueprint for the company’s development. The first step is to refine the pressure-sensitive chip to achieve high-quality development; the second step is to strive to be listed on the Science and Technology Innovation Board around 2023, and at the same time expand the range of sensors to temperature sensors, humidity sensors, Displacement sensors, angle sensors, etc., strive to become a beautiful business card in China's intelligent field.
