Rebirth of Northern Technology

Chapter 616 CMOS image sensor

November 6, Sunday, 8 o’clock, Qiulin Community.

Cheng Yongxing went downstairs to pick up the car.

Since traveling in Andong, he has moved back to Bingcheng for a business trip, and he has moved to live in Qiulin District.

After all, the room area here is larger, the layout of the apartment layout is more reasonable, and the surrounding living and business conditions are better.

The closed management of the community has also improved the safety factor, especially when Liu Xuan is alone in the ice city, which is even more important.

At 8:30, when the two people drove to the main entrance of the main building of the University of Technology, the two yellow sea buses were ready for departure.

The event was hosted by Manager Lin Tianpeng. He has been Zhang Luo before and after running.

The original Secretary Lin is now a secretary.

He and his secretary, one person and one passenger, took everyone to the Maoershan Ski Resort.

This time the game is funded by the talent fund to entertain foreign teachers who come to Bingcheng for training.

Cheng Yongxing did not go to the big bus, but drove to follow.

His car was also full.

Liu Xuan in the passenger seat, Li Lina in the back of the car, Zhang Xingchen and his girlfriend Hu Jing, this is his only remaining fellow team.

Following Cheng Yongxing’s car were four cars, Feng Yan, Li Dan, Hao Yunli, and Yang Sishan, following in turn, with family or friends following behind.

Yang Sishan took his wife Wei Suhua behind the palace.

Wei Suhua has been diagnosed with pregnancy, so he drove carefully until the end.

Going home this time, the two of them are going to make up a wedding, and it will be too late if the wedding is not held.

His return to Bingcheng this time is considered a debriefing. After the wedding, the two of them will rush to Sichuan to take up their posts. He will go there to serve as the general manager of the Mianyang base.

The main reason why Quancai set up a new large-scale base in Mianyang is Changhong, where the largest domestic appliance company is located. In this era, the size of Changhong is a giant in the color TV industry.

Cheng Yongxing talked with him about Lin Weifang’s work in the past. Yang Sishan is actually not very good at semiconductors. Adding to his girlfriend’s reasons, after several trade-offs, he decided to stay in Quancai for development.

There are several classmates staying with him in Quancai. These people were generally promoted to the first level by surprise.

————————

Hao Yunli’s car was second to last in the team.

In the car are some of her cadres. She also has a team now.

The investment promotion conference in August changed the life direction of many people, and Hao Yunli was one of them.

She decided to stay and start a business, and then go to work for others, no matter which university she was, she couldn’t inspire her interest.

Her entrepreneurial project is semiconductor sensors.

After years of twists and turns, things are back to the starting point.

Semiconductor sensors are a big field, and naturally there are choices. The first selected sub-project is CMOS image sensor.

The idea to start the project came from some of the ideas involved when students talked about biochips two years ago.

Image sensors have been around for more than 20 years.

The current technology is CCD, but its process is very complicated, only a few manufacturers have it, and the cost is relatively high.

Due to the high cost of CCD image sensors, the main application markets are military, aviation, aerospace and other fields.

For example, the unmanned camera cooperated by the University of Technology and Bingfei is equipped with a simple CCD camera to transmit the image back to the control center in real time.

This kind of camera has an accuracy of less than one million pixels and is more suitable for real-time monitoring, but it has no meaning as a camera.

There are CCD image sensors with higher pixels, but they are not available on the market.

You can only see them through the news occasionally, such as spy planes and spy satellites.

————————

CCD and CMOS technology, from the principle point of view, the same area, the same process, CCD has a higher pixel density, not to mention the CCD technology is quite mature.

However, the special process prevents it from enjoying the dividends of wafer chip process progress.

The pixels of civilian-grade CCD sensors reached 1.4 million pixels in 1986, and it had been more than eight years in 1994, and it was actually unable to make progress.

Eight or nine years ago, even if the CCD production line used the most advanced process, it is now 4 to 5 generations behind the mainstream process.

No one can explain the reason for this.

There may be technical obstacles, but the greater possibility is the cost.

The current image sensor has low resolution, but the price is not low, coupled with the expensive memory chip, the market cannot be opened quickly.

There are also some so-called digital cameras in the market, but they are more of a gimmick. The mainstream camera manufacturers have not set foot in this field.

CCD manufacturers need time to recover their investment costs, so they have lost the motivation to continue to upgrade their production processes.

This is not the case with CMOS technology. There is no essential difference between the manufacturing technology of CMOS sensors and ordinary chips. Ordinary fabs can directly transform production.

Once the CMOS image sensor can be commercialized, it will bring crushing advantages to CCD technology from the two dimensions of image accuracy and price.

Two years ago, Hao Yunli did not choose CMOS as the main research direction, because it was more of an innovation in craftsmanship. As a research project, it is of little significance.

But now, it is more appropriate as an entrepreneurial project.

Of course, I didn’t choose CCD technology because of helplessness.

Japanese manufacturers have established absolute dominance in the CCD field. No new player can circumvent the layers of patent barriers they laid down.

Especially at the civilian level, even the US KODAK could not enter this field. Later generations had to cooperate with the Japanese manufacturer Olympus to solve the patent barrier problem.

————————

In order to start this business, Hao Yunli went bankrupt and spent $2 million. She sold all the stocks and put up a little savings. As the founder, he holds 60% of the shares.

Professor Wang Liguo, there is also a US private equity fund, each with 5 million US dollars, each accounting for 10% of the shares. The remaining 20% ​​of the shares were taken away by the Testing Institute, and they became the second largest shareholder with technical support and 50 million yuan.

The total investment of the project, regardless of technology, has reached 150 million yuan in cash alone, which is considered a relatively large investment in Bingcheng. Coupled with the reputation of quasi-Nobel Prize scholars, it has been highly valued at the provincial and municipal levels.

Hao Yunli’s name is very recognizable after years of publicity, so her company is called Liyun Technology.

This time she returned to China to start her own business, and she enjoyed many conveniences.

The first point, needless to say, is financial support.

Corporate financing, technology and projects are often second, and people and trust are the first.

As a student who went out from the University of Technology, Hao Yunli had a high degree of recognition, especially from the College of Testing and Professor Wang Liguo. Everyone was very familiar with it.

The second is the industrial environment.

Time flies, and Ice City has developed into a major semiconductor town.

The benefits of the LED and LCD industries are beginning to spill over. Cheap lithography machines and other semiconductor equipment flood the market. It is not difficult to build a low-cost semiconductor chip factory.

In addition to the colorful, full-color semiconductor regular army, relying on the Institute of Semiconductors, Inspection Institute, Electronics Institute, Precision Instrument Institute, has established many small fabs of different scales and accuracy. It produces and processes low-cost chips for civilian use and toy grade.

These large and small fabs provide a good entrepreneurial soil for a group of entrepreneurs.

Talents, technology, equipment, and funds have a clustering effect in the ice city.

Third, resource borrowing.

Hao Yunli’s entrepreneurship has received invisible support from many sources. Many resources can be borrowed.

For example, the MEMS laboratory.

The MEMS laboratory is not what it used to be. It occupies three floors and is no different from a small fab.

This experimental fab is dedicated to Liyun Technology. This alone can save her construction period of one to one and a half years.

There are many similar things.

Hao Yunli’s name is still very appealing. With the strong support of the Institute of Testing, a young and energetic R&D team has been formed.

————————

The more support you get, the greater the hidden hope and the greater the responsibility you bear.

Hao Yunli put all her body, mind, and wealth into her work, just as she did for the IBM project.

With the support of multiple parties, Liyun Technology has continuously made major breakthroughs in technology. During this period, more than one hundred patents were applied for.

If it goes well, the first CMOS camera samples will be available before the Spring Festival in 1995.

Of course, compared with mature CCD technology, CMOS technology still has a long way to go. For example, CMOS cameras have problems such as high noise and insensitive lighting in low-light environments.

But Hao Yunli is confident about this because she has a clear technical roadmap. The gains in the past few months have continuously proved the correctness and value of this roadmap.

In the choice of route and direction, Liyun Technology has never made a big deviation.

Just like the original MEMS and biochips.

Of course, the time to enter the CMOS field is now more mature than two years ago.

Two years ago, the ice city did not have such a good semiconductor environment.

If the research was done at that time, it is more likely that these inventions and patents were all made for others.

————————

After more than an hour’s drive, the convoy quickly drove into the ski resort.

The current Maoershan Ski Resort is not the kind of ski resort with comprehensive facilities in later generations. There is no place to spend the welfare costs of photoelectricity, and this semi-natural ski resort is the result of misspending money.

After everyone received the equipment, they started free activities.

Skiing is a new thing even for Cheng Yongxing. Before going abroad in the previous life, there were no conditions, and after going abroad, there was no opportunity.

So today, like Liu Xuan, I was very excited.

Since it is not a formal ski resort, there is no so-called coach in the venue. Making a fool of yourself or watching others make a fool of yourself is the only pleasure for everyone.

All morning, everyone had a great time, and it was not until almost two o’clock that they were so hungry that the team left the ski resort.

The place to eat is regarded as a farmhouse, and also a designated dining place for the Optoelectronics Department.

The main product of the farmhouse is farmhouse dishes. A lot of stews such as white meat and blood sausage, sauce bones, cauldron chicken and so on were quickly brought up.

Although the dishes are very farm-style, they are also found in the city. It is not too rare. On the contrary, there are several dishes related to tofu that are more popular.

The tofu here is different from what is done in the city. It is made with brine, and the taste is very full. Even the flavor of tofu mixed with green onions is different.

————————

After eating for a while, slowly, the content of the conversation tilted towards the parents.

Many of the classmates sitting here have objects and are facing the problem of getting married. In Bingcheng, 24 or 5 years old, they have reached the age to discuss marriage, especially for girls.

The fastest here are Yang Sishan and Wei Suhua, they are considered Fengzi married.

Among the others, Li Dan and Feng Yan have a stable relationship with the subject. The relationship between two people and their boyfriends has a history of at least 5 or 6 years.

On the table, there are two lonely people, one is Hao Yunli and the other is Li Lina.

The two of them have not looked for ideas in the short term, one is starting a business, and the other is not only starting a business, but also learning. Basically there is little time.

Ma Yue left Jiangong’s army and also moved to Liu Xuan’s table.

“Cheng Yongxing, when are you getting married?”

Ma Yue and Liu Xuan have a very good relationship, and under the multiple relationships, they are very familiar.

“It depends on her.”

Cheng Yongxing tilted his head.

“Look at me?”

Liu Xuan was surprised by this answer. No one had ever talked to her before, and how could it be her turn to call the shots?

Not only her, but everyone else at the dinner table also has the same idea.

Ma Yue didn’t continue the topic, she felt that Cheng Yongxing just didn’t want to make a direct promise, just looking for a crappy excuse.

The chat content quickly moved to the weather and the content of the next activities.

————————

Cheng Yongxing did not continue this topic either.

In the previous life, the two people often quarreled over trivial matters until they got married.

Arguing about whether to go abroad or how to go abroad. In addition, as they participated in various overseas interviews, the frustration after failure also brought negative emotions to the relationship between the two people.

There were other things, and there were a lot of messy things. Cheng Yongxing didn’t even remember why it was noisy or what it was.

Two people are people with strong personalities, people who want face, many times, the two people quarrel directly under the street lamp.

Liu Xuan was living with her father in the family area of ​​the design institute. Many colleagues saw this scene from the window. This resulted in someone introducing him to someone until he got married.

The final catalyst for their marriage was the house.

The design institute divides the house every two years. Due to rumors at the time, the division of houses in 1996 was the last time.

Cheng Yongxing’s mother, Xi Fenghua, did Liu Xuan’s work personally before she got her marriage certificate first.

The strange thing is that after the two people got the testimony, the quarrel quickly reduced, which was a big surprise to those around them.
