Chapter 330: New MS6502

In the semiconductor laboratory of Jiangxi University of Science and Technology, Zhou Minde's research is still continuing.

It's just that compared with the actual test of the VCD chip before, in the face of the improvement of the MS6502 chip, Zhou Minde is more focused on theoretical calculation.

On the one hand, this is because VCD chips are relatively easy to make, but at the level of MS6502, the difficulty of production increases exponentially; On the other hand, it is also due to the open source research of MS6502, Zhou Minde has been doing it for several years, so it can be regarded as handy.

In short, Zhou Minde and his assistant Xiao He and the others accurately optimized the MS6502 through a large number of calculations, deleted the useless transistors that were used as test or backup lines, and redesigned the remaining transistors, and finally raised the process from 8 microns to 18 microns under the premise of retaining performance.

Don't underestimate the change of 10 microns, if it is 8 microns, then no one in the entire Jiuhu Province has the ability to mass production, but if it is 18 microns, it is possible to rely on contact lithography machines for mass production.

Of course, Zhou Minde is not as simple as directly enlarging the chip arrangement, as an old man who has dealt with semiconductors all her life, she knows very well that any chip must have redundancy, so as to ensure that the chip can run stably.

Otherwise, if a transistor is broken at random, it will not be usable, and that is a failed design.

After repeated demonstrations on the drawings to confirm that they were correct, Zhou Minde and Xiao He began to build chips for power-on tests.

In fact, whenever Zheng Nan came to the laboratory and saw the rows of chips for power-on tests, Zheng Nan always admired Zhou Minde, the 18-micron process can be made in the entire Jiuhu Province is one of the handful, but Zhou Minde can make so many at once here, I can't help but admire.

Zhou Minde told Zheng Nan that this was a laboratory practice, with high cost and high failure rate, which was not suitable for large-scale production at all, and what Zheng Nan needed was lower-cost mass production.

Zhou Minde also told Zheng Nan that MS6502 is a mature chip design, so even if it is streamlined, the performance will not be checked too much, and now don't look at the power-on experiment, but Zhou Minde is already very confident that it can be put into commercial use.

"All of the current energizing data for the MS6502 is better than expected." Zhou Minde said. If he had gotten this news before, Zheng Nan would have been very happy, but now Zheng Nan is not happy, the reason is very simple, he does not have a foundry now.

Chen Zhouyi has clearly refused to continue to OEM chips for himself, and the study of the people of Nanyuan Electronics Factory is only half of the learning, it is said that the gluing has just ended, and there are photolithography and etching in the follow-up, etc., it can be said that the progress is too far, what can I do.

At this time, Zhou Minde gave Zheng Nan a good idea: "Director Zheng, you can use the lithography machine of Jiangxia Electronics Factory!" ”

Of course, Zhou Minde said this not to let Zheng Nan and Li Xing operate, in fact, this kind of precision work is like a mountain across the line, not to mention that they don't understand, even if Zhou Minde comes by himself, it may not be better than any experienced technician in the radio factory.

Zhou Minde explained that it was for those people in the South Park Electronics Factory to practice.

"Although I don't understand the technical process of industrializing chips, I think it must be a set of sophisticated and complex skills, and it is impossible to learn them all in a month, without them having the conditions to practice."

"Now the radio factory is watching very closely, I'm afraid there are not many opportunities, so I can replace it with Jiangxia Electronics Factory."

This suggestion made Zheng Nan's eyes light up.

Yes! Anyway, in order to verify the technology, those people in Nanyuan Electronics Factory are not the same as taking the model chip or the new MS6502.

I am not in a hurry now, I don't ask for their yield rate, and when the time comes, there will be a piece is a piece, which is a good way to save time and materials.

And when they produced the new MS6502, they could take it to Zhou Minde for power-on experiments.

made a decision, Zheng Nan immediately arrested Li Xing from the workshop office, and asked him to put aside the gradual research for the time being, and get the chip workshop out first.

Li Xing rolled his eyes when he heard it: "Director Zheng, have you forgotten that our clean room workshop is still being renovated!" ”

Zheng Nan then remembered this stubble: "Haven't you finished decorating it yet?" ”

As a last resort, Li Xing once again gave Zheng Nan science the necessity of a clean room, and also emphasized that this kind of workroom decoration that must be spotless is also destined to be cautious, at least not for now.

But Li Xing also saw Zheng Nan's thoughts, and he said: "But it's not true that there is no way at all, we can still directly take the design drawing of MS6502 and replace the original chip sample for teaching, and the result is the same." ”

Let's try it soon, everyone. 】

Li Xing also reminded at the same time: "It's just that we need to worry about being caught by that Director Chen." ”

This is also what Zheng Nan needs to worry about, and Zheng Nan is not only worried about this, he is also worried that the new MS6502 drawings carefully researched by Zhou Minde will be prostituted by Chen Zhouyi, although the problem is not big, but Zheng Nan is unwilling.

But soon Zheng Nan made a decision: contact Fang Huanzhi and change the picture!

The reason is simple, Zheng Nan saw the news about the radio factory on the table.

On the news, Chen Zhouyi was full of spirits and announced in a high-profile manner that 2,000 home computers had been sold, and he hoped that all the workers of the factory would make persistent efforts to create greater brilliance, and he especially praised his deputy chief engineer He Gong.

This made Zheng Nan keenly feel that Chen Zhouyi was disgusted with Liu Gongsheng, who agreed to teach technology, otherwise how could there be no chief engineer Liu Zhenguo for such a major thing as a new product, but what deputy chief engineer to push? Isn't this out of order?

And now the sales of the red and white machines of the radio factory are hot, and Chen Zhouyi must put more of his energy on the red and white machines, as long as Liu Gong doesn't say it, no one will know about his change of pictures.

What's more, if you're lucky, you may be able to turn Liu Gong, an experienced chip engineer, around in the future.

As soon as he thought of it, Zheng Nan immediately took the drawings of the new MS6502 and went to the radio factory with the old director Li Xing.

As Zheng Nan expected, Chen Zhouyi is now full of profits from the red and white machine, although he appeared in the workshop as soon as he got his news, but he also emphasized that he was not allowed to go to other workshops, and could only stay in the chip workshop.

"Don't think I don't know what you're here for, now our home computers are selling well that is our ability, if you want to do something to steal chickens and dogs, if you infringe on our trade secrets, don't blame me for turning my face!" Chen Zhouyi even warned rather arrogantly.

Zheng Nan really wanted to laugh out loud, just that bullshit red and white machine he was a treasure all day long, but he didn't know that he would easily overturn his market.
