His lifetime success has contributed to a number of achievements in favor of Great Xia, and he is the initiator of the large aircraft project and the promoter of Entropy Fly's settlement in the magic capital.

He is the founder and guardian of Zhongxin International, and the planner and guide of Zhangjiang Hi-Tech semiconductor industry

In addition, he also has a great role in promoting the semiconductor equipment industry in Daxia.

For example, lithography machines and etching machines and other equipment are also recommended by him to focus on investment, it can be said that he is a real patriotic person, and he is also a person who has made great contributions to Daxia!

Such a person deserves Lin Xuan's respect, and he also deserves Lin Xuan's attention and salute him!

"Mr. Lin is really young, and he also developed the first mobile phone chip in Daxia, successfully breaking the monopoly of foreign mobile phone chips, which is enough to make celebrity history."

Obviously, both patriots, Jiang Haizhou has a good impression of Lin Xuan.

In this regard, Lin Xuan did not proudly go to the sky, but waved his hand slightly, and then humbly admired the other party:

"Where, I just developed a mobile phone chip, without my research and development, there will definitely be other people who will develop mobile phone chips in the future to break the monopoly of foreign mobile phone chips, which is nothing.

On the contrary, Mr. Jiang Haizhou successfully promoted the establishment of Zhongxin International, which had a profound impact on my Daxia!

Compared with a mobile phone chip in my R&D area, you are truly enough to leave a name in history, and you are destined to be an unavoidable person in the history books! ”

"You're overrated."

Obviously, Lin Xuan's sycophants were extremely correct.

At this time, although Jiang Haizhou forcibly kept himself from showing a smug and happy expression on his face, he couldn't hide the happy emotion in his eyes.

Not to mention other large aircraft incidents, the incident that prompted the establishment of Zhongxin International is definitely an achievement that he can boast about.

Because of this, he is destined to accompany the history of Zhongxin International celebrities in the future and become an inescapable person in the history of Daxia chips.

At the same time, seeing that the politeness between the two came to an end, Professor Yang, the president of Zhongxin International, also began to introduce others.

"This is Mr. Liang Haigang, the technical director of our Zhongxin International, who is responsible for the semiconductor master in our chip production and R&D process, and is an important core force for our Zhongxin International to develop and improve the yield rate."

"Hello."

Lin Xuan smiled and stretched out his hand, but there was no enthusiasm on the other party's face, he just nodded slightly, letting Lin Xuan's hand hang in the air.

Seeing this, Lin Xuan put away the smile on his face, looking at the other party's attitude, this guy seemed to be a little bad with him.

Professor Chen looked at Liang Haigang and didn't seem to have a good impression of Lin Xuan, and after he didn't even bother to shake Lin Xuan's hand, he hurriedly explained:

"I'm sorry, I'm sorry, Mr. Liang Haigang is not very good at human relations because he is often engaged in front-line technical positions, Mr. Lin, don't mind, come, I'll introduce you to other people."

"Yes."

Lin Xuan nodded lightly, and let go of this matter.

And that Liang Haigang didn't say anything, he still stood there indifferently, not knowing why he seemed very indifferent to Lin Xuan.

"This is ......"

Next, Professor Chen introduced many middle-level executives of Zhongxin International to Lin Xuan one by one, and it seems that Professor Chen attaches great importance to the cooperation of Hantang Technology.

As everyone sat down, Professor Yang also looked at Lin Xuan slowly, and said in a joking tone:

"We welcome the Tang generation chip order submitted by Hantang Technology, but there is something that may need to be explained to Hantang Technology."

"Please."

Lin Xuan nodded and motioned for the other party to speak.

Seeing this, Professor Chen sighed and said helplessly:

"In fact, although our Zhongxin International's process technology broke through to 90 nanometers last year, in June this year, we also officially completed the production of the first 90 nanometer chips.

However, since the official production of the first 90-nanometer chip in mid-June, we have not solved the problem of the yield rate of the 90-nanometer process.

Therefore, every time we produce a chip now, we lose money, and the more we produce, the more money we lose, so ......"

The next words don't need to be said by Professor Chen, Lin Xuan also understands that it is nothing more than losing money in production, and there is no way to accept Hantang Technology's order to mass-produce chips.

The production of chips is not simply a matter of letting the lithography machine shine on the wafer, and there are many steps in the actual chip production.

Such as lithography, etching, ion implantation, metal deposition, metal layers, interconnects, wafer test and dicing, core packaging, grinding, testing.

Among them, there are four major costs in the process of chip production, which are four parts: wafer cost + mask cost + testing cost + packaging cost.

The cost of packaging accounts for about 5%-25%, and the mask cost is the cost of using different process processes, and the mask cost of different process processes is different, and the current 90nm is about 1 million.

In other words, the yield rate is actually the chip hardware cost = (wafer cost + testing cost + packaging cost + mask cost) / final yield rate.

The process processes and steps of 120nm and 90nm are different, and the process steps between them cannot be used with each other.

Therefore, the current 90nm process technology is equivalent to a new road, and the yield rate of Zhongxin International at the beginning is very low, which is a normal phenomenon.

Zhongxin International can increase the yield rate of 90-nanometer chips to 80% or even more than 90% in a few months, which is really unscientific.

After all, it is a new process and a new production method, so it is no wonder that the yield rate can be rapidly improved.

If the chip wants to improve the yield rate, it depends on experience after all.

If you want to improve the yield rate, you need to sum up the experience in failure, then study the reason for each failure, and then improve it in the next production and adjust the data parameters slightly.

If the parameters are adjusted, the yield rate will become worse, and if it succeeds, the yield rate will increase slightly.

In the end, when countless successes are superimposed, the yield rate of the chip will increase rapidly, and finally reach a terrifying 99%. Or the legendary 98.9999%.

Therefore, the road to improving the yield rate is a road to burn money, after all, not everyone is like Lin Xuan.

You can perform countless simulations directly in the copycat space, and you don't need to spend a dollar at all!

For Lin Xuan, improving the yield rate of chips can best play the role of his golden finger!

In reality, chip production is required in the process of improving the yield rate of chips every time, and chip production costs money!

But for Lin Xuan, it doesn't take any money to tape out or improve the chip production process in the copycat space!

Every time others improved the process, they were shocked when they looked at the terrifying amount of money that improved the yield rate, but for Lin Xuan, it was a trivial matter.

Because even if the production equipment is broken in the process of improving the yield rate, Lin Xuan only needs to "refresh" it.

Lin Xuan can carry out countless failures, and even carry out various violent modification experiments on the equipment, and finally gain various experiences through countless failures.

Because there is no time and equipment cost, Lin Xuan can immediately "refresh" the equipment after getting the experience of failure, and directly start the next improvement.

In the end, through countless improvements and countless simulations, the yield rate of the chip was finally increased to a terrifying 9.999%!

This is the arrogance of a systematic person!

For Lin Xuan, there is a super copycat king system that wants to improve the yield rate, which is simply like a tiger with wings, and it can give full play to the usefulness of the copycat function.

It's a pity that Lin Xuan doesn't have the money to buy Zhongxin International now, if Lin Xuan can buy Zhongxin International, then with the buff function attached to the system.

With the function of the system, the yield rate of Zhongxin International can be directly increased by 15%!

Coupled with the 15% quality blessing, Zhongxin International may be the first chip foundry in the world with a chip yield rate of 100%.

But it's a pity that Lin Xuan has no money now, and he can't afford to buy 67% of Zhongxin International's shares.

Now, despite a round of blows by TSMC, the market value of Zhongxin International is still not something that Hantang Technology can look up to.

Its market value is still more than ten times that of Hantang Technology Company, and they still have a market value of 40 billion!

But now Zhongxin International is a behemoth for Hantang Technology, compared with Zhongxin International, Hantang Technology Company is just a child in front of Zhongxin International.

This shows how terrifying Daxia's support for Zhongxin International has been in the past two or three years since the establishment of Zhongxin International!

To talent to talent, to money to money, to land to land! To policy to policy!

But unfortunately, it's too late to say anything now, as Zhongxin International was caught in a patent dispute with TSMC last year.

Seeing that the future of Zhongxin International is uncertain, and the huge Zhongxin International may go bankrupt at any time due to patent issues, Daxia's support for Zhongxin International will naturally decline.

Therefore, the life of Zhongxin International is not easy now, without the continuous financial and talent support of Daxia, the current Zhongxin International seems to be very depressed.

"I wonder what the yield rate of your current 90nm chips is?"

Lin Xuan asked Professor Chen curiously.

The yield rate determines the profit level of the chip foundry, if the yield rate is low, it will lose money, and if the yield rate is high, it will make money.

For example, the yield rate of Lianfu Kota is very impressive, and their yield rate can usually reach 97%.

Some old chips that have been in production for more than two or three years have an astonishing yield rate of 99%.

Therefore, their gross profit is also very amazing, and they can usually earn 50% of the foundry profit per chip!

Perhaps with such an astonishing profit, Lianyuke has a large amount of money to invest in scientific research, so that its chip manufacturing process and technology have been at the leading level in the industry.

So this is the truth of the strong and the strong!

"This ......"

Professor Chen looked at Lin Xuan's straightforward question, he was a little embarrassed, but since Lin Xuan asked, he couldn't hide it.

“7％！”

Professor Chen of Zhongxin International has made a shameful number.

The yield rate of chip production is 7%, which is estimated to be said by Chen Damou of TSMC is estimated to laugh off his big teeth, and the world's major chip foundries are estimated to show a disdainful smile.
