Chapter 188: Optical Drive Control Chip

Leaving in August and meeting September, not long after the osmanthus trees in the courtyard of the Computing Institute were fragrant, there was a thunderstorm in the northern capital, and the temperature had plummeted by five degrees before the cold snap arrived.

Cool is always better than hot sweating, Jiang Yunshun didn't know which nerve was not good that day, he chatted with a melon seller at the door of the house, and finally bought a whole four large snakeskin bags of watermelons, and with the efforts of everyone, they were all piled up into the real yΓ n room.

"Isn't this September, the watermelon is not far from the market, and besides, he picked the melon before the rain, and it is very sweet. Jiang Yunshun explained.

Peng Bin rolled his eyes: "Didn't you hear that melon dealer say that he has several younger brothers and sisters at home, so don't put up with it." ”

Jiang Yunshun smiled: "Probably, I don't know." ”

Cao Yunuan came back from washing a melon in the bathroom opposite, cut it and ate it by himself. Huang Haishi took a slice and gnawed on it: "How long are you going to eat so many watermelons? Boss Jiang, are you crazy, aren't you? I think we should send a bag to Xia Lao?"

Li Xiuming said: "I think it's okay." ”

Hu Yiting also came up to eat watermelon: "Well, then it's so decided, Lao Jiang, you and Xiuming together, move a bag downstairs, in Sexia's car, don't forget to leave two for the driver and Tu Mi."

Everyone nodded yes. Nowadays, even if it is a trivial matter in life, as long as Hu Yiting opens his mouth to command, Dahuo has become accustomed to nodding and doing it, and the formation of this habit is Hu Yiting's trust won with his strength.

Relying on the efforts of a group of management talents such as Wang Lili, Ma Huateng, and Wu Hengyuan, Chongguang's business is growing at a rapid speed.

According to the news from Intel, Wu Tongtong, manager of Intel's China Department, conveyed their answer to Wang Lili by phone, and sure enough, as Hu Yiting expected, Andy Grove blatantly rejected Chongguang's request for architecture authorization, and raised the acquisition offer of Chongguang to 150 million US dollars.

Hu Yiting was unmoved, and stayed in the computing institute all day long, wholeheartedly studying his optical drive control chip, which carried a lot of his hard work.

The reason is very simple, although Hu Yiting is very cool to copy the film, the industrial control has always been his knowledge weakness.

Taking advantage of the opportunity to develop this chip. In the name of the joint efforts of the Institute of Computing, the Institute of Microelectronics, and Chongguang Company, Hu Yiting held several technical exchange meetings in the Institute of Computing, and took this opportunity to help him understand some little-known doorways in industrial control chips.

Xia Lao loves Hu Yiting very much, and Hu Yiting at this time is like a pearl in Xia Lao's eyes. For fear that he would accidentally be criticized in the dust, he took the lead in inviting a number of authoritative experts in the field of domestic computer industrial control to attend the meeting.

Experts from all walks of life heard that Chongguang Company had developed an optical drive control chip, and they couldn't believe it at first, thinking that this thing was an assembly technology product of machinery, motor, optics, and microelectronics, and it was the most advanced thing in the world. At present, even the video recorder in China has just been played, how can it be possible to overcome the core technology of optical drive control chip so quickly.

But everyone didn't know that this was the VT7160 chip produced by VIA in 2002, that is, seven years later, and seven years of technological development is enough to turn the sheep's tail sharp meat of the past into today's Chinese cabbage.

Fortunately, this chip has been successfully taped out at any cost on a new 0.8 to 1.2 micron process line that was debugged and completed by the Institute of Microelectronics of the Chinese Academy of Sciences last month.

In order to come up with samples, Chongguang Company paid more than 1.1 million yuan in tape-out fees, and Hu Yiting paid for it without hesitation.

1.1 million is enough for ordinary people to start a company and do business in 95 years, but in the field of chip manufacturing, this money may not even be able to make a splash.

Hu Yiting could have also chosen to go to the Taiwan Union current sheet. Although Hong Kong Feilong Company acts as an intermediary, after all, the two sides have dealt with each other many times and are already familiar with each other, and the price is generally 20,000 to 50,000 US dollars for a mature process like 0.8 microns according to the standards of Taiwan Union.

But Hu Yiting still chose the Institute of Microelectronics of the Chinese Academy of Sciences, and only wanted to make a small contribution to China's technological progress.

In order to tackle key scientific research tasks of the 908 Project, there have been big holes in the funding, and even the operating funds have been pasted into the scientific research funds to ensure the completion of the project.

Therefore, in the face of Chongguang's tape-out request. The Institute of Microelectronics offered a price of 1 million yuan plus some service fees, hoping to make some money to subsidize the institute. In the eyes of the Institute of Microelectronics, Chongguang Company, which holds the patent for the coprocessor of the Youying Overlord Coprocessor, is definitely a super big money, and I don't know how much money it has made with its green dollar bills!

Seeing that the Institute of Microelectronics is so ignorant of the market situation. Hu Yiting just smiled, didn't bargain, and simply agreed, but made a request, the tape-out must be completed within seven days, otherwise 100,000 yuan will be deducted for a day. Drag on for ten days, 1 million will be deducted.

For this business, all the researchers at the microelectronics institute were mobilized, debugging the test line 24 hours a day, and completing the tape-out in five days, the problem is that the pass rate of the post-inspection is only 3%, that is to say, only one or two pieces on a 6-inch silicon wafer are qualified products.

Later, Wu Dengchao, director of the Institute of Microelectronics, gritted his teeth and said: "Isn't the cost of a silicon wafer just a few thousand yuan? The heavy optical tape-out contract asks us to provide 30 chips, and even if we have only one good chip on a chip, 30 silicon wafers will not exceed 100,000 yuan! Comrades! The rest is all the year-end bonus of the institute!"

As soon as they heard this, the people of the Microelectronics Institute were immediately stimulated, and worked overtime to take out the 30 chips that Chongguang Company wanted. After several process adjustments, the pass out rate also increased from 3% to 9%.

At that time, in the conference room of the Institute of Microelectronics, although there was no celebration scene of red flags and drums, all the people in the Institute of Microelectronics were happy.

Wu Dengchao, the director of the institute, held Hu Yiting's hand and said to him sincerely: "Thank you for the trust of Chongguang Company and the choice of our microelectronics institute as a partner, so that we can have the opportunity to directly obtain benefits from the market for the first time." ”

Hu Yiting shook his head: "No, I should be grateful to the Institute of Microelectronics, if it weren't for the fact that the Institute of Microelectronics developed the VDMOS semiconductor device process for motor speed regulation and inverter as early as 91, then I wouldn't even have a choice, so I could only go overseas to tape out." ”

Wu Dengchao was stunned for a moment, solemnly held Hu Yiting's hand and said, "Good boy." You can say that again. ”

Hu Yiting said with a smile: "Face is earned by yourself, not given by others, if the power semiconductor device technology of the Institute of Microelectronics is not up to standard, then it will not be possible to realize the chip design of our Chongguang Company." Microelectronics has all the amazing technology. Chongguang Company can cooperate with top scientific research institutions like you, and it is an honor!"

Director Wu Dengchao smiled and slapped Hu Yiting on the shoulder: "Okay, if Chongguang Company has a job in the future, even if you come to the Institute of Microelectronics, we will cooperate with you as much as possible to achieve your goals!"

Hu Yiting nodded with a smile. The heart said that it would be sooner or later.

"Then Wu Suo must give me a cheap price. ”

Wu Suo's face flushed, and he said seriously: "I have already reported to the higher authorities, and I hope that the country will give priority to Chongguang Company as a market technology partner outside the system in the future semiconductor design research projects." ”

Hu Yiting was happy in his heart, his order this time was actually regarded by Wu as a vote, and sure enough, sometimes it is a blessing to suffer losses.

Wu said: "Our test line was originally set up to lay a pre-station for the 908 project, and the 0.8 micron process technology was pre-researched in advance, but who would have thought that the 908 project would not survive like a difficult birth, alas. It's hard to put into words. ”

Then Wu Shu joked: "But fortunately, today with the list of your Chongguang Company, let us open a meat." ”

All the people who participated in the acceptance meeting and technical appraisal meeting laughed.

Soon after the completion of the acceptance, Hu Yiting began to hold a technical appraisal and product promotion meeting in the computing institute in the name of the three strong alliances of the Institute of Microelectronics, the Institute of Computing, and the Chongguang Company.

At the meeting, Chongguang Company used samples, combined with several common general-purpose optical drive movements on the market, to perfectly realize the input and output of the control signal, and the stepper motor control of the optical drive head can be described as flawless, and the reading speed and mechanical error correction ability of the disc number jΓΉ are shocking.

That's when the experts at the meeting realized. The domestic industrial control chip has actually solved the problem of optical signal processing and micro-dynamic control under ultra-high-speed operation. And judging from the performance parameters obtained from the test, the domestic industrial control chip is not worse than Philips's at all, and even reaches a speed of 110 milliseconds to find the address, and the stepper motor is as dexterous as a swallow under the control of this chip. You must know that at present, Philips has just launched a four-speed optical drive control chip, and the industrial control chip design ability of a small domestic IC design company such as Chongguang Company has reached such a high level!

Yang Yuancheng, a well-known researcher from an electronics research institute of North Industries Corporation, couldn't help but say excitedly: "You Chongguang Company really want this chip......! It has been able to greatly meet the requirements of the use of core control components of a product of our company!"

Another researcher from NORINCO, who came with him, said excitedly: "I think the key to achieving this performance is that this chip has successfully integrated the unique design of multiple field-effect transistors! This design can control the number of output pulses to achieve the precise displacement of the control motor, which I have only heard of in foreign countries before." I have never seen it with my own eyes, but Chongguang Company actually has this kind of design capability! The Institute of Microelectronics has also been able to successfully tape out the fabrication! This shows that this kind of design is feasible! It is really a genius technology!"

"Yes, in the past, we even thought it was incredible that the addressing speed of 350 to 500 milliseconds of the double-speed optical drive, but your Chongguang company has improved it to 110 to 250 milliseconds of the four-speed optical drive in one fell swoop, especially the highest performance parameter of 110 milliseconds, which can be compared with Philips!" said an expert from a technical university.

Xia Lao, who was sitting next to Hu Yiting, looked proud, and whispered a few words to Hu Yiting, Hu Yiting hurriedly said: "You have also seen that this addressing speed is achieved with the imported Philips or Toshiba's optical drive stepper motor.

Yang Yuancheng, a researcher from NORINCO, immediately said: "Our company can manufacture this kind of precision stepper motor, and the laser head ...... I remember that Wuhan also has relevant civilian research, and it is not difficult to produce products. However, at present, the production cost of precision stepper motors has not come down, we used to lack cheap control chips to match, if you rely on imported chips to produce optical drives, the final cost is more expensive than direct imported optical drives, and now the chip can be domestically produced, I think you can try. ”

Hu Yiting scratched his head: "At present, it is only a successful tape-out, and the pass rate is not high." ”

Yang Yuancheng said with a smile: "No matter how high the cost is, it won't be more expensive than Philips, right? Philips's two-speed control chip costs $100 a piece, do you have to sell this piece for 800 yuan a piece with four times the speed?"

According to the current 9% pass rate, although the price of each piece is less than 800, it is nearly 400 yuan after packaging, and such a cost of casting will definitely not satisfy Chongguang Company.

Hu Yiting said: "There is no reason for our IC design and manufacturing companies to pay for your terminal product manufacturers, your stepper motors and laser heads are expensive to manufacture, but our chips have just come out, and the cost is also very high."

Besides, the mechanical structure of the stepper motor does not have much future in the future, to achieve precision control, the future bald head must use voice coil motor or even ultrasonic motor to control the machine, and the spindle should also be replaced with a brushless DC servo motor. I've heard that Philips, Panasonic, Toshiba, and even LG are already doing research in this area, so I don't know what China is doing now.

Yang Yuancheng said: "Isn't that all the technology on the hard disk?

Hu Yiting nodded: "This is the trend, the optical drive will definitely be faster and faster in the future, where is the 4 times speed, I think it will develop to 32 times or even more than 50 times in the future." ”

Yang Yuancheng sighed: "Sure enough, it's the trend of the times, we have also had this conjecture, but I always feel that it is still far from that day, but I didn't expect that foreign countries have already started to do it." ”

Hu Yiting said: "We can also do it, but we must first meet two conditions, first, we must be experts, and second, we must have a demand for products."

The second point is the most important, as experts can sometimes be hired externally. However, if the market demand cannot be guaranteed, the risk of the hardware manufacturing industry is too great, once the technology is not as good as the people, you can only fight the cost, coupled with the pressure of product development verification cycle and capital return, it is easy to go bankrupt.

Whether it is for precision motors or laser heads, Chongguang is not an expert, and as an IC company, we have no demand for these two products. ”

Yang Yuancheng thought for a while: "These two points, our northern company can't be satisfied. ”

Hu Yiting smiled helplessly, did he have to rely on imported optical drive movements for the VCD industry chain planned in his mind? )
