As a key project in Hunan Province, my country's first pressure-sensitive sensor chip production line with completely independent intellectual property rights was successfully launched in Liuyang High-tech Zone on January 16. In the early morning of February 10, the reporter rushed to Liuyang to visit the pressure-sensitive sensor chip production workshop.
At the door of the workshop, we were greeted by Professor Wang Guoqiu, a PhD supervisor from the School of Mathematics and Statistics, Hunan Normal University, who is also the chairman of Hunan Qitai Sensing Technology Co., Ltd.
He smiled and said, "Reporter Xu, when you interviewed me 12 years ago, I said that I would build a production line for manufacturing chips. Today this dream has come true."
Work overtime on New Year's Eve without stopping
(On February 10th, Qitai engineers worked in the ultra-clean workshop.)
On New Year's Eve, Wang Guoqiu brought more than 10 engineers from the company to the front line of pressure-sensitive sensor chip production. "Although the line is successfully connected, the product is undergoing testing and cannot be interrupted. Everyone is working hard on New Year's Eve."
After changing clothes and cleaning twice, the reporter entered the ultra-clean workshop of Qitai Sensing Internet of Things Industrial Park. Yang Yan, the manager of the microelectronics department, was "fully armed". She stayed in the workshop every day and did not rest for a day. She showed us the process of chip manufacturing, metal base laminating, etching, cleaning, developing, testing, etc.
Yang Yan is still very excited to work overtime every day. She said: "The pressure-sensitive sensor chip production line has been successfully completed. We are particularly fulfilled. Our team is working hard and hopes that the chip performance will be more stable and the parameters will be better and better, so as to provide the market with A better product."

Qitai pressure-sensitive sensor chip is a functional chip made on a metal base, which directly converts force signals into electrical signals, and is widely used in a variety of force sensors such as traffic, fire protection, and water treatment. At present, Wang Guoqiu's team has declared 11 invention patents and 6 utility and appearance patents.
Wang Guoqiu said that after the current pressure-sensitive sensor chip production line is put into operation, there will still be a three-month ramp-up period for the yield. If the yield rate reaches more than 90%, mass production can be achieved. "After production, it has to go through more than 3 months of testing to ensure that there is no quality problem. Mass production and sales will be possible in August this year."
12 years of perseverance, to overcome the key problems in the whole process of chip production
In the integrated circuit industry, the six parts of equipment, materials, design, production, testing, and packaging constitute the upstream and downstream industrial chain. Enterprises have their own responsibilities and coordinated development. An enterprise generally only does one of them.

However, when the pressure-sensitive sensor chip production line was built and completed, Wang Guoqiu led the team to persevere in research and development, breaking through one problem and one problem, and overcoming the problems of the whole process of chip production. He proudly said, “The core technology, key processes and equipment of the pressure-sensitive sensor chip production line, plant design, chip inspection, and packaging are all independently completed by our team. As a chip designer, I don’t want anyone to get stuck in the chip production line. Neck."
The difficulties behind completing independent research and development are often anxious. Wang Guoqiu will not only take the lead in overcoming R&D technical problems, but also raise 120 million yuan in production line process research and development and equipment purchases.
In 2010, in the fourth year that Wang Guoqiu led the research and development of pressure-sensitive sensor chips, the company experienced a serious financial crisis. In order to repay the debt, he took out all the more than 4 million yuan he had accumulated, and went around raising funds to tide over the difficulties. He didn't dare to let his family know about this matter.
R&D, fundraising, and development are all things that make people anxious. When all the things came under pressure, Wang Guoqiu bluntly said that he had faced collapse several times and wanted to give up. Because after 16 years in the army, I always have a sense of mission in my heart, strong ability to withstand pressure, every time I give up for 3 days, and I must work hard.

According to Wang Guoqiu, it is estimated that 500,000 pressure-sensitive sensor chips will be produced this year. After being packaged into sensors, the annual output value will exceed 500 million yuan. In the second half of this year, the second phase will also start construction. After completion, it will achieve an annual output of 20 million pressure-sensitive sensor chips. After being packaged into sensors, the annual output value will exceed 15 billion yuan.
The pressure-sensitive sensor chip market is mainly in four major areas: one is the transportation field, including automobiles and rail transit. The pressure sensor chip of the body stabilization system developed by Qitai can be assembled in the car instead of imported. The second is a smart city. The third is oil and gas and petrochemicals, and the fourth is special industries.

The reporter saw that in the lobby of Qitai Company, there were fire hydrants and fire water pressure monitoring systems, and the data was updated on the big screen in real time. A pressure-sensitive sensor chip is placed in the fire hydrant, and the water storage and water pressure in the fire hydrant are fed back to the fire department and community owners in real time, which is conducive to the timely fire fighting of the fire hydrant. Among the currently planned markets, transportation and smart cities are the two main markets.
