Vincent spent a day in Yuanxin Technology Park. He visited several departments of Yuanxin in addition to the dust-free workshop with great enthusiasm. Especially after seeing the mobile communications department, he said that only Yuanxin from the mainland could form such a huge R&D team in just two years.

Of course, he didn't know that there was only one such number as Yuanxin in the entire mainland... and he could only be called half a team.

At noon the next day, Su Xinghe also returned to the Science and Technology Park and accompanied Vincenti for lunch as chairman of Yuanxin. During this period, Su Xinghe did not mention cooperation - he needed to stand up for his son with practical actions, saying that his son was the actual helmsman of the entire Yuanxin.

...

"Old Jiang contacted the relevant companies during the TB exhibition. We can temporarily confirm that if we only look at the equipment, we can actually put together a wafer factory now, such as the current laboratory."

Su Yuanshan and his father were walking under a thirty-meter-long grape shackle. This grape shackle was a thirty-meter-long grape shackle that Su Yuanshan strongly asked for transplantation last year, saying that when walking under the grape shackle, it was cool, and when it was fruitful, it could still be picked and eaten. It was so pleasant to think about it.

He thought it was pretty, but he forgot that this thing is the easiest to attract mosquitoes. If he was lucky, he might fall down his head after walking around.

In the clean room of Yuanxin, in addition to a lithography machine, there is also foreign garbage collected from NEC. These foreign garbage can barely cut out five-inch wafers. In addition, a set of equipment such as etching and lithography, Yuanxin Laboratory can also tinker with several chips regardless of the cost.

Su Xinghe smiled and looked at his son: "A wafer factory has process technology and technology are very important."

Su Yuanshan nodded: "In a sense, process technology surpasses equipment."

"The reason why China packages and introduces equipment and processes is that there is nothing, and the second is that it is hoped to upgrade the process after understanding the technology thoroughly. But now it seems that this road is about to fail."

Su Yuanshan pursed his lips, looked at the end of the grape trellis, frowned: "The process technology is actually about mathematics, physics and chemistry, and the current situation of our basic disciplines... To be honest, it is really difficult to deal with without foreign experts and returnees with technology."

As the chip industry at the peak of "artificial objects", the importance of process technology is actually far greater than that of equipment - the simplest example, in later generations, TSMC's 7nm was ahead, and Gross Fonde, Samsung, UMC, and TI could not catch up with it? Intel's 10nm has been delayed for many years - you should know? They have no restrictions.

As for Samsung to catch up with him later, it was because Lao Liang passed by.

I felt distressed when I thought of Liang Mengsong and Su Yuanshan? Last year, Liang Mengsong still jumped to TSMC along the original trajectory. But at that time, Yuanxin? He didn’t even have the qualifications to contact others...

He is a process engineer at a wafer factory, and Yuanxin doesn’t even have half a production line? How to poach people?

"Take it slow." Su Xinghe saw his son frowning and patted his shoulder with a smile. He comforted him: "I heard that Jianguo is in the clean room? Are he studying process technology?"

"Well, that's true. I asked him to explore the copper interconnection technology." Su Yuanshan said, smiling self-deprecatingly: "We think too far and go too fast. There are very few people who can help now."

The copper interconnection technology here naturally refers to a process of replacing the existing aluminum metal interconnection materials with copper metal materials. Compared with aluminum, copper has good resistance and temperature resistance. It is the core process technology to increase frequency in the future.

TSMC took the lead in developing copper interconnects under the 0.13 micron process, surpassing UMC in one fell swoop.

It has been nearly five years since Su Yuanshan proposed the concept.

Su Yuanshan certainly could not master the copper interconnection process, but he knew the direction.

Since copper has a large diffusion coefficient in silica? At the same time, the adhesion is also very weak, there must be a barrier layer outside the copper interconnection wire to prevent its diffusion. In order to better plating copper, a thin layer of Cu seed crystal is also needed to first generate a thin layer of Cu seed crystal on the process circuit...

The methods for generating Cu seed layer include physical vapor precipitation, chemical vapor precipitation and atomic layer deposition.

After the copper seed layer is generated, electroplating can be performed and finally polished to complete the interconnection.

At present, Chen Jianguo is making up for relevant knowledge. At the same time, the whole country is running around. He visited experts in related fields everywhere.

As a junior brother and the proposer of the project, Su Yuanshan can only support him in terms of money...

...

The father and son separated down the office building. Su Xinghe was very busy. He wanted to make the final technical summary of the 16-bit microcontroller and help his son make money.

Su Yuanshan is also busy and has to do experiments.

Nowadays, various laboratories in Yuanxin have been arranged in full swing.

Because in addition to the experiments in the Science and Technology Park, the Electrical Science and Technology schools in the Provincial University of Science and Technology have also submitted various experiment applications.

Of course, these schools have laboratories, but in terms of advanced or complete equipment, the Yuanxin Science and Technology Park, which has just been established, has unparalleled advantages.

So... the current situation is that even if Su Yuanshan comes to the physics laboratory, he has to wait for arrangements.

When he entered the laboratory, he saw a familiar person in front of the Hall effect lab.

"Sister Qu Hui?" Su Yuanshan called softly.

Qu Hui was still short-haired and was analyzing data with a technician. Hearing this, he turned around and smiled at Su Yuanshan: "I heard that you also want to do a Hall effect test?"

"Well, but it's okay. I'm just playing. You guys are busy." Su Yuanshan smiled and thought about it and asked again: "What are you doing this experiment?"

"Oh, I want to analyze the interference problem of Hall sensor." Qu Hui pursed her lips and walked towards Su Yuanshan: "I did it from the servo motor team, I'll come and take a look."

"Oh! Then I'll wait a moment." Su Yuanshan paused and smiled: "The Hall effect tester is very cheap. Get a few more next time."

At this time, someone immediately received: "Mr. Shan, get a few more atomic force microscopes."

Another voice came: "There is also a scanning electron microscope."

“…”

Yuanxin Technology Park mainly has two relatively large physics laboratories, one of which is an optical laboratory and the other is its laboratory that mainly focuses on condensed matter physics research.

Now these guys have turned his condensed matter laboratory into a conventional laboratory, and various basic experiments are ready to go.

Su Yuanshan was also a little drunk.

Seeing that everyone was ready to open a list, Su Yuanshan quickly said goodbye to Qu Hui.

Just as he was about to leave the laboratory, Ye Rudai's little head just reached into the door.

"leaf?"

"Brother Xiaoshan." Ye Rudai was startled and immediately said happily: "What a coincidence."

"Yeah." Su Yuanshan smiled and stood beside Ye Rudai: "Would you do the experiment?"

"No, I'll ask about the data." Ye Rudai's eyes circulated and pointed to the innermost: "Look at whether the test results and simulation functions are correct."

Su Yuanshan nodded with a smile: "Then you go over, I'll wait for you, and then go upstairs together to take a look."

"Okay." Ye Rudai responded simply and walked quickly to the innermost point.
