Rebirth of Northland Technology

"Should these CMP technologies be handed over to both of us?"

Too much information is obtained today.The two young people felt dizzy.

Multi-pattern technology, you can understand at the first listen, and dare to illuminate.But CMP technology involves real swords and guns.

Mechanical grinding, what to do with grinding fluid, grinding speed, machining accuracy, none of these are simple.

The two of them faced the same problem as Cheng Yongxing. After all, the learning time was too short and the basic knowledge was not reliable.

"I will give these technologies to others for research and development."

This CMP technology is also very important, but there is no need for confidentiality.Because it is an open technology in itself.Now it's a comparison, who adopted it first.Early adoption, early benefit.It can be done in a fair manner.

This is why this technology is called true 1 micron.

CMP technology is placed in the foreground as a guise, and the multiple pattern technology is hidden behind.

"Are you going to hand it over to Director Zhao?"

"I will arrange it separately. You don't have to worry about it."

This is indeed a headache.

In terms of integrated circuit technology, the University of Technology has also made some achievements in the past two years.

In addition, there are specializations in surgery.It is simply not realistic to rely on more than a dozen people in a professional field to cover the world.

Director Zhao led a group of disciples, already running wildly in integrated circuit design.Then let them go on.

Many of these technologies are systematic.It doesn't even rely on one or two equipment, one or two equipment manufacturers can handle it.

The introduction of third-party forces is a must.

But this matter is not urgent.The role of a guise is mainly a guise.

"What are we doing now?"

"The first step is to verify the concept first, and also to experiment to see which of the two paths, LELE and SAMP, is easier to implement and the least difficult."

There are two ways to achieve the multiple pattern technology method.One is LELE and the other is SAMP.

LELE decomposes the design layout into two sets of independent low-density graphics, through two separate exposures and two separate etchings, and then superimposed together to form a finer pattern.

SAMP is to form the core pattern by one photolithography, then form sidewalls (SideWall) on both sides of the core pattern by deposition (Deposition), and finally achieve the desired pattern by etching (Etch) and trimming exposure.

"You proposed these two paths, don't you know?"

Yan Liang thought this thing was a bit strange.

"I haven't done it myself, how do I know?"

"Is this really your own idea?"

"What are you asking so much for? Too much curiosity will kill the cat, don't you know?"

"We are not cats! Never mind, who is rare!"

A person does not live in a vacuum, as long as the time is long, there will always be some trouble.In the past, Cheng Yongxing would always find excuses to explain, and slowly, he didn't even bother to find excuses.

This is why he only believes in these few people around him.At least these classmates, fellow villagers, he can trust them.

It's a pity that there were only two people left in the Whampoa Army.Due to the lack of trusted assistants, many of his ideas could not be implemented.

"If this is the case, the 908 project is not necessary at all! If this is the case, can you tell the country to spend part of the 908 project?"

"You don't need to consider the state's appropriation. In the 908 plan, the state did not give out any appropriation. They are no different from ours. They are all bank loans."

"In the end? How did you know this? Forget it, I won't ask."

Optoelectronics is making every effort to sprint the production capacity of LCD, and the second line has reached the stage of spending money like water.

This is another investment in units of 100 million yuan, which cannot be supported by optoelectronics' own funds alone.The real support for optoelectronics' large-scale investment is actually bank loans.

In the past two years, Optoelectronics has borrowed from all major banks in Bingcheng.

Many companies in Bingcheng went to the city government to file a complaint, saying that their normal business activities were affected.These enterprises are all genuine state-owned enterprises, and their voices are also very loud.

This kind of voice actually existed last year.

The emergence of the Optoelectronics Group did have a squeeze effect on Bingcheng’s social funds.Optoelectronics received more bank loans, and naturally, the bank loans received by other companies decreased accordingly.

Especially during the most serious period of triangular debt in 1991, the emergence of optoelectronics made the operating conditions of many companies worse.

But the emergence of optoelectronics is not entirely a negative effect.The first is the rise of the LED industry chain, which has activated the entire electronics industry.These are the companies that have the heaviest burden and do not need government relief.

Secondly, the sales market of optoelectronics is basically for the international market, so the funds it brings are completely additional funds.This part of foreign exchange income needs to be converted into renminbi when it reaches the country. This kind of renminbi is an additional issue.In other words, there will be an equal amount of funds in the banking system of Bingcheng.

The positives and the negatives are offset and roughly equal.But it's hard to say when it comes to certain companies.

"Without state investment, where does the investment in the construction of the fab come from? Are you preparing for the fab and TFT-LCD to proceed at the same time?"

Optoelectronics has already owed a debt.Those owed to banks, equipment suppliers, and construction units.Had it not been for the face of the big-screen LED, the money maker, it would have been a long time ago to gather for money.

"First, this fab will not start so quickly. The start of this project will at least wait until the LCD project is on the right track, that is, after "Full Color Technology" makes money."

"When is that probably?"

"My expectation may be the end of the year, maybe next year."

To build a new fab requires a lot of preparation.It is not only a plant, but also includes human resources.

The human resources of TFT-LCD are actually trained through the LED industry.

"Second, the investment in the new factory will not be so large. We do not need to pursue too high a production line index at once."

When Cheng Yongxing was studying several major projects in history, he could not always understand some ideas of the past.

Take 908 as an example. The goal of this project is to produce 12,000 chips, a 6-inch, 0.8-1.2 micron chip production line per month.

At this time, China's actual process level is 4-5 inches and 2-3 microns.In this case, the goal of the 908 project actually includes two big improvements, one is 4 inches-6 inches.The other is 2 microns-1 microns.

So the question is, why should two major advancements be implemented in one project?

Is it good to come one by one?Solve one, then solve the other.

Excessive standards made the project more difficult, and it took seven years to complete.As soon as it was built, it became obsolete.

Cheng Yongxing has become accustomed to the method of fast running in small steps.

In the LED era, "Huge Hi-Tech" is evolving technology on a quarterly basis.

In the LCD era, "Full Color Technology" evolves forward with a half-year cycle.

In the wafer age, the pace of advancement is at most in years.When the money goes down, you will see splashes soon.

"How do we divide the work?"

"This multi-pattern technology verification is mainly based on Ye Jing."

Cheng Yongxing thought for a while, and felt that Ye Jing's calm character would be more suitable.

Multi-pattern technology is very simple in thinking, but in history, many companies have stumbled on this process, indicating that it is still somewhat difficult.

But Cheng Yongxing also has his advantages.That is the information he knows, and it is the result of various manufacturers' hard work.

It's like, in liquid crystal technology, he is only familiar with TFT technology.He didn't know what was going on with CSTN and what technical know-how, because later generations didn't pay much attention to this eliminated technology.

In any case, the difficulty of this technology is only a matter of how it is used, and there is absolutely no problem that cannot be done.
