Return to the exciting era of 1999

Chapter 1709 Conquer with strength

Mr. Zhou remembered the logo above. It was an indispensable and important component for the communication company's signal tower. It used to be imported from Texas Instruments, but now some of it is domestically produced. Unexpectedly, Ji Donglai's factory also provided support for this processing plant.

"To be exact, we made it. We have been cooperating with this factory in Pulandian since 2000. Later, they were preparing to transform, and we directly bought 70% of their shares and the other %. Thirty is a ten-dollar investment to hold!”

"We are currently exporting this sensor very well. The sensors on the communication equipment in Central Asia are all ours. We are also in the market in the Middle East. We have already won over Saudi Arabia, Kuwait, Iraq, and Turkey. Angola in Africa is not far behind either.”

"The one you are holding is a low-end sensor. This one is a higher-end sensor with six 28nm chips embedded in it. It is an indispensable product on the transmission tower. This year we have received hundreds of millions of orders."

"Originally, we had a lot of chip orders for medical devices. Later, Yiyuan Medical was acquired, and we almost stopped the production of related chips. Recently, there have been a lot of orders from India, and we started doing it again..."

For each product, Ji Donglai could easily tell the origin, manufacturing process and customers. This made Mr. Zhou highly admired.

In another sterile showroom, a huge wafer was densely covered with lines. Mr. Zhou almost lay on it to look at it. Ji Donglai handed him a magnifying glass.

He took out his mobile phone, entered the password, and the display cabinet opened in a few minutes. Mr. Zhou picked up the chip with one hand and looked at the incandescent lamp carefully.

"This chip is pretty good. Do you have a microscope?"

"There is a second dimension here, check it out there!"

Knowing what Mr. Zhou wanted to see, Ji Donglai pointed at the two-dimensional object next to him, and his assistant turned on the light. In a matter of minutes, Mr. Zhou had begun to adjust the handle, and the structure of the chip was clearly visible under the lens.

Each branch is densely packed, thinner than a hair, and has neat edges. There are no cracks as expected, and there are no adhesions that occur during chip sputtering. It is perfect.

"Mr. Ji, is this really not etched by a photolithography machine?"

The nearly perfect texture aroused strong suspicion on Mr. Zhou's side. It was almost perfect.

According to existing theories, except for the photolithography machine process, there is almost no process technology in the world that can produce qualified chips that conform to people's logical concepts in a short period of time.

According to modern control theory, even if the finfat process is used between conductive media, too close a distance will cause discharge.

The chip circuit produced by photolithography machine etching technology combined with vapor deposition can barely meet the factory's needs, and the other methods of conductive circuits are not perfect.

A little more precious metal sticking out will cause discharge, which will cause the chip to short-circuit and overheat, affect the logic error of the chip, and seriously reduce the service life of the product.

Mr. Zhou's department has been waiting for domestic factories to buy good photolithography machines for many years, and then produce qualified chips for their own end products. However, photolithography machines are not just precision equipment that you can buy just because you want to.

You have to place an order two years in advance, and then the other party will do it for you based on your mood and laws. Once the law says it cannot sell to you, the other party will directly send the contract back to you. Therefore, so far, almost no one in the Chinese place, except TSMC, can produce qualified chips in batches. The chips produced by Ji Donglai's factory were so perfect that Mr. Zhou had to be suspicious.

这次被米国商务部处罚金额达到了8.92亿美元，折合人民币62亿人民币。给米国商务部工业与安全局3亿美元（折合人民币20亿元）。总计罚款金额高达11.92亿美元，合计人民币约82.2亿元，据称创造了美国有史以来出口管制案的最高罚款纪录。

If there were no restrictions on technology in various aspects, the center could completely ignore the punishment.

Obtaining suitable high-tech replacement is the wish of every center employee, and Mr. Zhou, as the leader in this area, is equally urgent.

China's microelectronics industry is still very, very backward, and its supporting industries are even more backward.

Around 2000, the IC industry needed to be heavily supported, and Chinese chips were everywhere. Mr. Zhou also participated in the design and manufacturing of some key chips of H when he was in school. However, after so many years, neither the talent pool nor the current status of the industry is very optimistic.

The gap between digital circuits and the United States is relatively small (the gap is still huge in terms of FPGA and CPU), and the gap in analog (especially AD) is very huge. As for devices that meet military standards, the gap between radio frequency devices is even greater. Many times you have to go through irregular channels to obtain it.

In the past 20 years, when integrated circuits were booming, there was a lot of investment in them, but when they were trough, almost no one cared about them. In addition, the income of industry practitioners has never been high. Even the income of silicon workers with ten years of experience is far less than that of Internet practitioners. Not to mention the income of mechanical and physics practitioners in supporting industries.

This punishment incident is a pity for 26 grassroots employees!

"Who provides your materials? Things like photoresist are very scarce. As far as we know, there are very few supporting factories in China. When you really supply, will you be stuck in the corresponding field?"

No matter what the processing technology is, Mr. Zhou's understanding is that protective materials are indispensable, otherwise such a thin circuit will be oxidized very easily.

"On the one hand, we have acquired several foreign photoresist manufacturers in China. Their processes and technologies have been fully authorized for us to use. We have completed continuous research based on the original formula and have made great achievements in the past few years."

"In addition, we have invested heavily in basic materials since 03. We have done very well with traditional silicon-based materials, and the other materials are still under in-depth research."

"For the time being, there is no material or technology in the world that can stick to our neck. If there is, it will probably only be cross-border competition. After all, we are an independent manufacturing process and find a new way."

Speaking of materials, Ji Donglai was not even worried.

Over the years, in the field of basic materials, under the leadership of Li Heping, the entire materials laboratory has developed various things that are needed by factories. The group of doctoral researchers brought by Li Dongzin are not vegetarians. The laboratory of the Polytechnic University can be said to be perfect in 20 hours. Open to Ji Donglai.

Mr. Zhou was worried, so Ji Donglai could only go to the material supporting factory in Ye County at the same time.

It wasn't until the entire visit was completed that Mr. Zhou left with peace of mind. He didn't say any follow-up words during the whole process, and Ji Donglai didn't bother to ask.
