Vincenti stayed in Yuanxin Science and Technology Park for a day, and he visited several departments of Yuanxin except for the dust-free workshop with great interest, especially after seeing the mobile communication department, he said that only Yuanxin in the mainland can set up such a large R&D team in just two years.

Of course, he didn't know that there was only one such thing as Yuanxin in the entire mainland...... And it can only be called half of the team.

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

......

"Lao Jiang's side contacted relevant companies at the TB exhibition, and we can temporarily determine that if we only look at the equipment, in fact, we can now put together a wafer factory, such as the current laboratory. ”

Su Yuanshan and his father walked under a 30-meter-long grape green trellis, which was transplanted by Su Yuanshan last year, saying that walking under the grape trellis would be cool, and when the fruit came to fruit, it could be picked and eaten while walking.

He thought it was beautiful, but he forgot that this thing was the easiest way to attract mosquitoes, and if he was unlucky, he might be able to drop a bed bug on his head after walking around.

At present, in the clean room of Yuanxin, in addition to a lithography machine, there is also foreign garbage from NEC, which can barely cut a five-inch wafer. Coupled with a set of equipment such as etching and lithography, the remote chip laboratory can also make a few chips regardless of the low cost.

Su Xinghe looked at his son with a smile: "For a wafer factory, process technology and technology are very important. ”

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

"The reason why the domestic packaging and introduction of equipment and technology is that there is nothing, and secondly, it is also hoped that the process will be upgraded after the technology is thoroughly understood, but now it seems that this road is about to fail. ”

Su Yuanshan pursed his lips, looked at the end of the grape trellis, and frowned: "The process technology is actually a puzzle of physics and chemistry in the back, and the status quo of our basic disciplines ...... To be honest, without foreign experts and returnees with technology, it is really difficult to get it. ”

As the chip industry standing at the pinnacle 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 is unbeatable, and Grofangde, Samsung, UMC, TI and others can't catch up? Intel's 10nm has been skipping tickets for many years - you know? They don't have any restrictions.

As for the Samsung catching up later, it is also because Lao Liang has passed.

Thinking of Liang Mengsong and Su Yuanshan, I felt distressed? Last year, Liang Mengsong still followed the original trajectory and returned to TSMC. And the far core at that time? I don't even have the qualifications to contact people......

People are process engineers in wafer fabs, and Yuanxin doesn't even have half a production line? How to poach people?

"Take your time. Su Xinghe saw his son frowning, smiled and patted him on the shoulder? comforted: "I heard that Jianguo is in the clean room? Are you researching process technology?"

"Well, sort of. I asked him to explore the copper interconnect technology. Su Yuanshan said and smiled self-deprecatingly: "We thought too far and walked too fast, and there are very few people who can help now." ”

Copper interconnect technology here? Naturally refers to the integrated circuit interconnection layer? It is a process of replacing the existing aluminum metal interconnect material with copper metal material, which has good resistance and temperature resistance compared to aluminum and copper. It is the core process technology for increasing frequency in the future.

TSMC was the first to develop copper interconnects under the 0.13 micron process, surpassing UMC in one fell swoop.

Now Su Yuanshan proposed the concept nearly five years earlier.

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

Due to the large diffusion coefficient of copper in silica? At the same time, the adhesion is weak, so there must be a barrier layer on the outside of the copper interconnect wire to block its spread. And for better copper plating? It is also necessary to generate a thin layer of Cu seed crystals on the process circuit......

The method of generating Cu seed crystal layer is divided into physical vapor precipitation, chemical vapor precipitation and atomic layer deposition.

When a copper seed crystal layer is formed? Plating can be carried out and finally polished to complete the interconnection.

And for now? Chen Jianguo is making up for relevant knowledge? At the same time, the whole country is running around? Visit experts in the field everywhere.

As a junior disciple and the proposer of the topic, Su Yuanshan can only support him financially......

......

The father and son were separated under the office building, Su Xinghe was very busy, he had to make the final technical summary of the 16-bit single-chip microcomputer, and he also had to help his son make money.

And Su Yuanshan is also busy, and he has to be busy doing experiments.

Today, Yuanxin's laboratories are full.

Because in addition to the experiments to be done in the science and technology park, schools such as the Department of Electricity, the Provincial University and the Institute of Science and Technology have also submitted various experimental applications.

Of course, these schools have laboratories, but no matter in terms of the degree of advanced equipment or the degree of completeness, the newly established Yuanxin Science and Technology Park has unparalleled advantages.

That...... The current situation is that even if Su Yuanshan comes to the physics laboratory, he will have to wait for the arrangement.

Entering the lab, he saw a familiar person in front of the Hall Effect Experimenter.

"Sister Qu Hui?" Su Yuanshan called softly.

Qu Hui still had short hair, and was analyzing data with a technician, when she heard this, she turned around and smiled at Su Yuanshan: "I heard that you are also going to do a Hall effect test?"

"Well, but it's okay, I'm playing tickets, you're busy. Su Yuanshan smiled, thought about it and asked, "What are you doing this experiment for......?" What are you doing?"

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

"Oh, then I'll wait. Su Yuanshan paused and said with a smile: "The Hall effect tester is very cheap, so get a few more next time." ”

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

Another voice received: "And the scanning electron microscope." ”

“......”

There are two relatively large physics laboratories in Yuanxin Science and Technology Park, one of which is an optical laboratory, and the other is a laboratory that mainly focuses on partial condensed matter physics research on his side.

Now these guys have turned his condensed matter laboratory into a regular laboratory, and all kinds of basic experiments are flying.

Su Yuanshan was also a little drunk.

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

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

"Leaves?"

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

"Uh-huh. Su Yuanshan smiled and stood beside Ye Rudai: "You came to do the experiment?"

"No, I'm going to ask for data. Ye Rudai's eyes flowed, and she pointed to the innermost: "See if the test results and the simulation function are correct." ”

Su Yuanshan nodded with a smile: "Then you go over, I'll wait for you, and then let's go up and have a look." ”

"Okay. Ye Rudai answered dryly, and walked quickly to the innermost.
