Technological Empire Starts From Shanzhai System Chapter 125

Chapter 125 Zhongxin International

His life has successfully contributed to many achievements that are beneficial to Daxia. He is the initiator of the large aircraft project and the promoter of Entropy Flight's settlement in Modu.

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

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

For example, equipment such as lithography machines and etching machines are also recommended by him for key investment. It can be said that he is a true patriot and a person who has made great contributions to Daxia!

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

"Mr. Lin is indeed young. He also developed Daxia's first mobile phone chip, which successfully broke the monopoly history of foreign mobile phone chips. In this regard, it is enough to be famous in history."

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

In this regard, Lin Xuan did not proudly go to heaven, but waved his hand slightly, and then bowed his hands to the other party and said in admiration:

"Where, I am just developing a mobile phone chip. Without my research and development, in the future, someone else will develop a mobile phone chip to break the monopoly of foreign mobile phone chips. This is not a big deal.

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

Promoting the establishment of Zhongxin International Compared with my research and development of a mere mobile phone chip, you are truly enough to leave a name in history, and you are destined to be an unavoidable person in the history books! "

"You are overrated."

Obviously, Lin Xuan's flattery was extremely correct.

At this time, Jiang Haizhou forced himself not to show a complacent and happy expression on his face, but he couldn't hide the happiness in his eyes.

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

Because of this, he is destined to accompany the history of Zhongxin International celebrities in the future, and become a person who is destined to be unavoidable in the history of Daxia Chip.

At the same time, watching the two people's courtesies come to an end, Professor Yang, the president of Zhongxin International, also began to introduce other people.

"This is Mr. Liang Haigang, the technical director of Zhongxin International. He is a semiconductor master in charge of our chip production and research and development process. He is an important core force for our Zhongxin International's research and development and improvement of yield rate."

"Hello."

Lin Xuan stretched out his hand with a smile, but there was no enthusiasm on the other party's face, he just nodded slightly, leaving Lin Xuan's hand hanging in the air.

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

Professor Chen saw that Liang Haigang didn't seem to have a good impression of Lin Xuan. After he didn't even bother to shake hands with Lin Xuan, he hurriedly explained:

"I'm sorry, Mr. Liang Haigang is not very good at human relations because he often works in front-line technical positions. Don't mind Mr. Lin. Come, let me introduce others to you."

"Yep."

Lin Xuan nodded slightly, as if he had let go of the matter.

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

"Who is this…"

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

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

"We very much welcome the Tang Feng generation chip order submitted by Hantang Technology, but there is one thing that may need to be explained to Hantang Technology Company."

"Please say."

Lin Xuan nodded, motioning for the other party to speak.

Seeing this, Professor Chen sighed and said helplessly:

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

But in fact, from the official production of the first 90nm chip in mid-June to the present, we at Zhongxin International have not solved the problem of the yield rate of the 90nm process technology.

So, we lose money every time we produce a chip, 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 can understand, it's nothing more than losing money in production, and there is no way to accept the order of Hantang Technology to mass-produce chips.

The production of chips is not simply to let the lithography machine illuminate the wafer. There are many steps in the actual chip production.

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

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

The cost of packaging accounts for about 5%-25%. The mask cost is the cost required by different process technologies. The mask cost of different process technologies is different. Currently, 90nm requires about 1 million.

That is to say, the yield rate is actually chip hardware cost = (wafer cost + test cost + packaging cost + mask cost) / final yield.

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

So the current 90nm process technology is equivalent to a brand new path. It is normal that Zhongxin International's yield rate is very low at the beginning.

It is really unscientific that Zhongxin International can increase the yield rate of 90nm chips to 80% or even more than 90% within a few months.

After all, they are all brand new techniques and new production methods. It is no wonder that the yield rate can increase rapidly.

Chips want to improve the yield rate, after all, they rely on experience.

If you want to improve the yield rate, you need to sum up experience from failures, and then study why each failure failed, and then improve it in the next production, and adjust the data parameters a little.

After adjusting the parameters, if it fails, the yield rate will become worse. If it succeeds, the yield rate will increase slightly.

Finally, when countless successes are superimposed, the yield rate of the chip will increase rapidly, eventually reaching a terrifying 99%. Or the fabled 98.9999%.

So the way to improve the yield rate is a way to burn money. After all, not everyone is cheating like Lin Xuan.

Can directly carry out countless simulations in the cottage space without any cost at all!

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

In reality, chip production is required every time the chip yield rate increases, and chip production costs money!

But for Lin Xuan, it doesn't cost money at all to tape out or improve the chip production process in the knockoff space!

Every time other people improve their craftsmanship, they are terrified when they see the terrifying amount of money that increases the yield rate, but for Lin Xuan, this is a trivial matter.

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

Lin Xuan can make countless failures, and even conduct various violent modification experiments on the equipment, and finally obtain various experiences through countless failures.

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

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

This is a systematic person who is arrogant!

For Lin Xuan, there is a super copycat king system that wants to increase the rate of good products.

It's a pity that Lin Xuan has no money to buy Zhongxin International now. If Lin Xuan can buy Zhongxin International, it will rely on the buff function attached to the system.

With the system function, Zhongxin International's good product rate can directly increase by 15%!

Adding 15% quality support, Zhongxin International may finally be the first chip foundry in the world with a 100% chip yield rate!

But it is a pity that Lin Xuan has no money now, nor can he afford 67% of Zhongxin International's shares.

Now Zhongxin International has gone through a round of blows from TSMC, but 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 the current Zhongxin International is a giant to Hantang Technology. Compared with Zhongxin International, Hantang Technology 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!

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

But it is a pity that it is too late to say anything now, as Zhongxin International got into a patent dispute with TSMC last year.

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

So the life of Zhongxin International is not easy now. Without the continuous support of funds and talents from Daxia, Zhongxin International is now very depressed.

"I don't know how your current yield rate of 90nm chips is?"

Lin Xuan asked Professor Chen curiously.

The yield rate determines the profit of 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 Renvacota is amazing, and their yield rate can usually reach 97%.

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

So their gross profit is also amazing, they usually earn 50% of foundry profit per chip!

Maybe with such an astonishing profit, Lianfa has a lot of money to invest in scientific research, so that its chip manufacturing process and technology have always been at the leading level in the industry.

So this is the truth that the strong will always be strong!

"This…"

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

"7%!"

Professor Chen from Zhongxin International gave a shameful figure.

The good product rate of chip production is 7%. It is estimated that Chen Damou of TSMC will laugh out loud, and the world's major chip foundries will probably show dismissive smiles.
