Hearing Yu Zixian's anxious plea for help, Aso Shunichi hurriedly said: "Don't worry, Yu Jun, I haven't finished talking yet...... I asked my friend about this question just now, but he was hesitant...... Finally, I propose that they supply 0.3 tons of photoresist according to your 1.2 micron lithography characteristics directly to our laboratory...... And the other party agreed, as for the rest of the matter, they don't care......"

"Wow, thank you so much professor, we are willing to buy this 0.3 tons of photoresist at double the price!" As soon as Yu Zixian heard it, he knew what path Aso wanted to take.

"This is not necessary, just take it as my support for Xiao Cai and your work! We may have other cooperation in the future...... Two days later, you sent someone to pick up the goods! I believe that this batch of goods is enough for you to hold on until the photoresist begins to supply normally...... After finishing speaking, Shunichi Aso pointed to the big red robe wrapped on the table and said: "The tea leaves of this two are also very precious, but what is more precious than her is our friendship!

"We must cooperate happily!" Yu Zixian was so excited, this amount of big red robes was too precious!

The photoresist matter was solved like this?! Shunichi Aso is really refreshing!

……

The next day, Shunichi Aso left with two of his students, along with Cai Junjie. And Yu Zixian made a special trip to see him off.

Cai Junjie followed to deliver the photoresist two days later!

At the airport, Yu Zixian saw Cai Junjie's sister's cold look, but Cai Junjie was still cheeky to help carry the suitcase......

"Director Cai, come on, look at that little bag, can you also help carry it......

So, Cai Junjie hurriedly walked up, pulling the suitcase with one hand and his sister's small bag with the other. Although the junior sister refused Cai Junjie's request at first, she still gave him a bag.

"Ah, yes, yes, Cai Junjie has made progress, at least the thickness of his skin is much thicker than before. Yu Zixian's heart is happy!

Good good study，Day day up！

It seems that everything is going in a good direction......

***

After Cai Junjie left, Yu Zixian was not idle.

According to the plan, in the past two days, Duan Yongping of Rubik's Cube Wisdom, Fu Zan of Huari Electronics and others will come to Xiangjiang with the latest version of the Little Doctor learning machine and the Big Overlord game machine...... While witnessing the birth of the mass production version of the chip together, we will also do the practical application testing of the 6502-XJ91 chip that has just come off the assembly line in the laboratory of Xiangji.

The meaning of the 6502-XJ91 code name is: this is the 6502 chip of WDC company produced by Xiangji - XJ: Xiangji, 91-91 began to produce.

At that time, the 6502-XJ91 chip will replace the 6502 chip imported from Bay Island, and realize the self-production and self-sale of the chip.

The significance of self-produced and self-sold chips is extremely important for the users of Rubik's Cube smart chips and the producers of Xiangji chips!

It indicates that after a year of hard work by Yu Zixian, Yu Zixian's various enterprises have promoted each other and achieved common development! From chip manufacturing to the application of chip products and terminal electronic products, a positive cycle has been realized.

This is what Yu Zixian is looking forward to very much!

October 1, 1991 is the day of celebration of the whole country of the Republic, and it is also the day of the final acceptance of the upgrading and reconstruction project of the 1.2 micron production line of Xiangji!

The ancients paid attention to "time, place, and harmony" when fighting wars.

In the past three months, in addition to the full participation and efforts of more than 1,200 personnel at all levels of the whole plant, there are more than 500 workers from the semiconductor factory infrastructure transformation in the early stage, and more than 200 technical personnel at all levels in various equipment factories and enterprises in the later stage of equipment installation and commissioning. Tomoki Kashima and Shunichi Aso, who was invited later, are actively cooperating, and under the premise of high quality, the construction teams of China, Japan and the Netherlands are fully committed and cooperative, and the construction period is about half a month ahead of the design period of the Japanese electronic design unit!

From the renovation of the main civil engineering project, to the decoration of the interior and exterior walls of the building, the expansion of equipment pipelines, the construction of outdoor road pipelines, the installation of power equipment, and the installation and commissioning of purification plants, etc., the construction of the strong team is no less than the construction of the new plant, but under the overall layout arrangement of Kashima Tomoki and Cao Fei, the early civil engineering, Jinjie team, the equipment installation and commissioning work of each factory in the middle and late stages is closely coordinated, cross construction, when the construction peak is the most people, in a place of several thousand square meters, there are more than 1,200 people working......

Fortunately, the "time of day" is good, and during the rainy season in Xiangjiang, God did not embarrass the Xiangji transformers too much, and there were no natural disasters such as heavy rainstorms and flash floods. However, in the future, once the plant area is expanded, the Xiangji power plant area near the mountainous area must take measures to prevent flooding and waterlogging.

All the hard work is worth it. In exchange for the installation of debugging equipment on the premise of ensuring the cleanliness of a large area of clean workshop, and to complete the commissioning task in advance, after passing the acceptance of the branch and carrying out a comprehensive acceptance, the transformation project of the 1.2 micron chip production line of Xiangji at this time is only put into trial operation.

Yesterday, after Yu Zixian once again confirmed Cai Junjie and the 0.3 tons of photoresist transferred by Aso Junichi, Yu Zixian finally thought about it and decided to follow the previous plan, on October 1, the 1.2 micron chip production line of Xiangji was officially put into trial operation.

Although everything was normal before the previous acceptance, everyone was not 100% sure before the production line was officially put into trial, and no one knew what the initial yield of the chip would be after the trial operation.

Even if production starts now, it typically takes at least 10 weeks to produce a wafer. Of course, in the trial production stage, due to the relatively small production volume, the production cycle can be compressed to the limit, but it still takes 10-14 days, and the number of wafers produced is also very limited.

In the whole production cycle, the wafer is photolithography, thin film, etching, cleaning, and injection through several modules of the front-end process of semiconductor manufacturing, and 2,000 processes are completed step by step according to the process flow to become an uncut bare die......

All that remains is to inspect and select the bare die, select the qualified and usable parts, and carry out the final packaging test. Only the chips that have passed the packaging test can be applied and sold on the market!

On October 1, 1991, at 11:16 p.m., the 1.2-micron chip production line of Xiangji was officially launched under the witness of the senior management personnel of the on-site participating units, and the results will be announced ten days later......

At the same time, Yu Zixian's hope for the future of Huaxia chip industry is also ignited!
