The surprising 6502-XJ91 chip was mass-produced by Xiangji, which created a miracle with a trial production yield of 55%. According to Kashima Tomoki's introduction, this yield is also a very good result in Yuben.

Confirmed with the production line design unit, after consultation with Kashima Tomoki, Cao Fei, and Liszt and other equipment manufacturers debugging personnel, everyone agreed that after a week, that is, after the production process of 6502-XJ91 chips on the production line is completed and all the wafers are rolled off the production line, the yield of all wafers will be counted again to confirm the final yield data, as long as it reaches more than 50, you can directly trial produce a 1.2 micron 16-bit version of the 65C816 chip.

If the trial production is successful, it will have its own name 65C816-XJ91 chip. At that time, using this chip, you can join hands with Rubik's Cube Intelligence Company to really design the Overlord version of SFC.

However, Yu Zixian feels that something is always missing, that is, even if the 65C816-XJ91 can be self-produced, it is still a general-purpose chip, not a custom chip optimized and designed according to the needs of Rubik's Cube Smart Technology Company.

In the case of general-purpose chips, it is possible that other manufacturers will still use the 65C816 chip obtained from other channels to imitate the Overlord version of SFC.

If you want to get a customized chip, you either have your own chip design company, which can optimize the corresponding chip layout according to your own needs, or you can buy the layout optimization design authorization of the chip design company and hand it over to a company with chip design capabilities to optimize the chip according to your needs......

In this way, the final production of chips will have the only authorization and chip production channels, even if other manufacturers want to imitate, there is no supply channel for chips, thus cutting off the possibility of imitation of Rubik's Cube Wisdom Company's electronic products from the source!

Nintendo's FC consoles and SFC consoles are prime examples.

Because the FC game console uses the 6502 general-purpose chip, although the price is cheaper, it should be a mature chip many years ago, and it is easy to be obtained by the Bay Island chip manufacturing company, for example, the 6502 chip purchased by the Rubik's Cube Intelligence Company from Lianhua Electric can be directly used to pirate Nintendo FC games.

And by the time Nintendo launched the SFC console last year, it was difficult to imitate. Because SFC uses a 16-bit Ricoh customized version of the 5A22CPU.

Due to the huge success of the FC game console, Nintendo's SFC launched last year still uses the 6502 architecture, with the 5A22 CPU clocked at 3.6 MHz and the maximum supported memory increased from 64KB to 16MB in the 6502.

Because it is authorized by WDC to optimize the design, Nintendo and Ricoh have a patent for the 16-bit 5A22 chip based on the W65C816 developed by WDC!

This is also what Yu Zixian wants to pursue! However, due to the lack of funds and design units, the design optimization authorization of WDC's 16-bit W65C816 chip was temporarily cancelled.

Just like WDC, since the production of W65C816 chips can be licensed to Nintendo, and it can be licensed to Magic Core Technology, then it can also be licensed to other factories. Who made W65C816 chip a general-purpose chip.

Fortunately, there is not so much urgency for the time being, at present, the SFC project of Rubik's Cube Intelligence is still in the design and development stage of software and hardware, and the W65C816 chip only involves a small part of the software, as long as the design optimization is completed in the mass production stage, and it is too late to modify it at that time.

So the key thing for Yu Zixian now is to make money! Only when you have money can you apply for authorization, or directly find WDC to optimize and customize the W65C816 chip of the magic core version.

This is also the reason why Yu Zixian is eager to trial produce 1.2 micron process chips, and after the test is completed, the basic upgrade of this line production line will be completed. The subsequent step is to fine-tune the production line process until the yield rate of 80% is reached.

After all, if you achieve full production with high yield one step earlier, you can make money by foundry one step earlier! Now the demand gap for high-end chips with small threads in the mainland is very large!

In the past 1990, the Republic of China consumed nearly 600 million integrated circuit chips, and its domestic circuits were only 100 million (9700000), not even 20%; and the most annoying thing is that the integrated circuit chips of less than 100 million are all low-end chips with 5 micron CMOS process and 3 micron bipolar linear process and above, and the added value is very low!

And the number one project of China's electronics industry during the "Seventh Five-Year Plan" period - Wuxi microelectronics project, although as early as 1983, the State Planning Commission has approved the construction of Wuxi microelectronics research and production consortium, but in the specific implementation process, up to now, four key tasks, has also completed the expansion of the 5-micron bipolar production line and the construction of some integrated circuit supporting facilities (the key part is basically very slow progress, subject to various embargoes), of which the key project of the domestic integrated circuit ICCAD tool compilation and so on is still in progress...... As for the most core project, the introduction and construction of a CMOS production line with 3-micron technology, progress is slow.

In the negotiation of the introduction of 3-micron CMOS technology that has lasted for many years, although there have been many contacts and negotiations with THOMSON in France, AT&T in the United States, Siemens AG in Germany, and NEC in Germany, there has been no substantial progress until now.

From 83 to 90 years, the Wuxi microelectronics project of the Republic of China contacted many major integrated circuit manufacturers in the United States, Japan and Europe, but has not been able to find a suitable partner.

Even if the "Siemens Contract on the Transfer of Technology for the Manufacturing of "2 Microns" and 3 "Microns" Integrated Circuits" signed by China and Germany on October 4, 1988 came into effect, because of the international influence (89 years) Siemens did not substantively perform the contract, and the Ministry of Machinery and Electronics Industry was forced to start the Siemens project without Siemens' participation after repeated considerations!

It was not until October last year, when the State Development Planning Commission basically agreed to the independent plan, that Siemens restarted and approved the cooperation project, and such a bad experience led to a waste of two years of time in the past 88-90 years.

Although the cooperation of Siemens later refused to approve the cooperation project due to the refusal of "Batumi", the "Siemens Contract on the Transfer of Technology for the Manufacturing of "2 Microns" and 3 "Microns" Integrated Circuits" was reduced to two stages, first "3 "microns" integrated circuit manufacturing technology transfer, and then 2 microns......

Despite all kinds of shrinkage and concessions, cooperation has still experienced various hardships.

On the contrary, the latecomers took the lead, that is, the later Shougang NEC project took substantial steps......

It's a bit far, but judging from the implementation of the country's largest integrated circuit project in the 80s, the country is not without its efforts, but because of the influence of various international external factors (Batumi), it has lost its rhythm in the implementation of the project and the grasp of the time node, coupled with the lack of investment experience in similar fast-paced large-scale investment industries...... The final result is really embarrassing.

Let every latecomer review the negotiation process of Wuxi microelectronics project cooperation from the beginning, and hold a sulk in my heart!

The failure of the Wuxi Microelectronics Project (later Huajing) did not pave a smooth path for the Republic's electronics industry...... In August last year, the integrated circuit 908 project proposed by the Ministry of Machinery and Electronics Industry, in March 92, a year later, officially submitted to the national "Integrated Circuit 908 Project Construction Proposal".

In this way, until April 1995, the 3-micron CMOS chip production line of Yangang Ridian integrated circuit project was officially put into operation, and it has been hovering above 5 microns in China. (It should be noted that CMOS process and bipolar linear process chips are two completely different chips, so they cannot be used universally.) In the mid-80s, the Republic introduced a 3-micron bipolar linear process to produce chips used in some color televisions. In the production of integrated circuits, the CMOS process is indeed widely used. ）

Therefore, after a year of hard work, Yu Zixian was still very excited and proud when Xiangji was able to produce a 1.2-micron chip!

However, this pride, Yu Zixian can only temporarily put it in his pocket and walk at night in brocade clothes.

Because he is still weak, once he attracts the attention of the electronics giants in the United States, Japan and Europe, only one semiconductor material will be shut down, and the production line of Xiangji will be shut down every second...... So at the moment, lewd development is the key!

However, the integrated circuit manufacturing industry of Xiangji has given Yu Zixian the possibility to expand to the upstream and downstream industries of chips.

Chip manufacturing is located in the middle of the integrated circuit manufacturing industry, with chip IC design, chip manufacturing equipment and semiconductor material companies in the upstream industry, and chip packaging and testing companies in the downstream.

If you go a little further, in fact, the ICCAD software service providers involved in chip design belong to the upstream.

At this time, Xiangji has the processing capacity of 1.5 micron (unless specifically specified in the future, it is generally the default CMOS process chip), but who is it foundry?

Is it right now to grab food with TSMC? It's very inappropriate! Zhang Zhongmou is a ruthless person, especially Zhang Zhongmou, who is already on Intel's father's thigh.

Besides, in two years, TSMC will be listed, and with TSMC supported by the American consortium, Yu Zixian feels that he will be even more unprovoked!

Unless two years later, Yu Zixian's thighs are thicker and bigger than TSMC's father's thighs!

But is there this? Yu Zixian didn't know...... Even if it is five years later, ten years later, it is estimated that Yu Zixian may not have it!

Everything depends on Yu Zixian's own hard work, and the whole industry chain is king. But at this time, the whole industry chain is just a dream for Yu Zixian!

The rest of the other American, Japanese and European chip manufacturers, let alone think about it. But apart from these foreign companies, who else owns the design rights of high-end chips, and then lets themselves do the OEM?

It seems to be really gone!

At this time in China, there is no integrated circuit design software ICCAD (I don't have it, and foreign countries embargo it), how to design chips, let alone design an advanced chip with small threads!?

Do you really want to set up a design company under Moxin?

There is no money, Yu Zixian feels like he is going to collapse!

Two days ago, Yu Zixian called Cao Fei to roughly count the total cost of the upgrade of the production line of Xiangji.

This time, the transformation of the production line of Xiangji was very smooth, especially in the yield rate, but these were based on a large amount of money.

The upgrade design of the production line, the transformation of the clean workshop, the entry of equipment and the installation and commissioning of the equipment are all bound by the contract, and basically the budget is not exceeded, but the salary of the installation and commissioning technicians is overpaid.

At that time, in order to ensure the yield, Yu Zixian deliberately asked the equipment manufacturer to send more technical experts and experienced technicians to the scene for guidance, and the final price was that the labor salary was paid in the past four months, which exceeded 1 million US dollars!

You must know that these technicians pay subsidies on a daily basis!

The 1 million, plus the 15 million that had been overbudgeted before, brought the total cost to $16 million!

So at this time, Yu Zixian didn't dare to think about other things!

He's got to get some money!

I went to the Soviet Union, saw Jiang Yuehua and them with my own eyes, and learned in detail about the implementation of the "Snowball Plan".

Although Jiang Yuehua had called before, saying that the "Snowball Project" was progressing normally, Yu Zixian knew that in a place where he was not familiar with life, especially in the Soviet Union, which was fed by European and American consortiums at this time, how could things go so smoothly!

It is very likely that Jiang Yuehua is just reporting good news and not bad news!

Now the collapse of the "Soviet Union" is less than three months away, and the most critical time for the "Snowball Project" is time. Therefore, the trial production of the 16-bit 1.2-micron 65C816-XJ91 chip of Xiangjidian is not waiting.

Counting the 3-micron to 1.2-micron process switching and other preparation time, it will take at least a month, and it is estimated that the trial production of the 16-bit 65C816-XJ91 chip of the Xiangji version will be completed by mid-November.

It is now October 15, and Moscow must be reached by November at the latest.

But before that, Yu Zixian still had to go to Yanjing.

If Yu Zixian doesn't go again, it is estimated that Comrade Lao Luo will have to run over to arrest him personally.

Just thinking about it, Yu Zixian saw a figure appear at the door. After Yu Zixian saw it, he smiled: "Slut, thief, if you want to come in, come in quickly, if you don't come in, I'll leave?"

At the door, Liu Jian asked nervously: "Ah, are you going to leave again?" Let me tell you, this time I came to study at Xiangjidian, but Director Luo gave me a death order, and you have to bring Kashima Tomoki over no matter what...... Otherwise, my salary will be assessed. ”

"Haha, the assessment will be assessed, and I will give you double it. Yu Zixian was happy and said with a smile.

"However, I'm going to study abroad at the beginning of the year, what will I do when the time comes?" Liu Jian said with a sad face.

"Hey, this Comrade Luo is too much, isn't it? I funded your study abroad funds, and I contacted you for the study abroad school, and he is embarrassed to take this card?"

Previously, with the help of Cai Junjie and Aso's mentor Shunichi was a professor at the University of Tokyo, Yu Zixian won Liu Jian an opportunity to study abroad at his own expense.

Lao Luo talked about Liu Jian, it seems that he was really forced to be anxious.

However, it is impossible for Tomoki Kashima to go, and now that the production of 1.2-micron chips has reached a critical moment, how can he be allowed to leave!

Besides, wasn't it very bullish in the city at the beginning, Yu Zixian just wanted to see how the other party could solve it.
