No matter how good the wafer fab process design is, it can only be considered a real success if offline verification and trial production are successful.

Originally, Wang Yi was planning to come over on the day the R&D plant was delivered, but Mr. Hu was in a hurry to get the equipment, so he asked Wang Yi to postpone it.

After all, the wafer fab’s factory buildings are different from other factories. They are all dust-free workshops, and the equipment inside are all high-precision equipment.

The installation of equipment in ordinary factories can be done in a big and easy way.

However, the entry and installation of wafer fab equipment are delicate tasks that require professional personnel to carefully install and debug.

Therefore, it took a full week before Wang Yi arrived at Factory No. 1, the R&D factory that was delivered ahead of schedule.

In the factory, many technicians are busy and some equipment is still being brought in.

"Chairman, you are here!"

Mr. Hu came over with a smile, and it was obvious that he was very excited.

Wang Yi nodded: "Let me see, the future glory of Xingyi Semiconductor will start from this R&D plant!"

"Yes, the glory of Xingyi Semiconductor starts from here!" Mr. Hu said with a smile:

"Generally, a 12-inch wafer fab can produce 10 wafers per month, or even 2.5 or wafers. Our wafer fab, with all three plants completed and put into production, can only produce wafers per month, which is considered a small wafer fab. The disadvantage is that it is small in scale and has limited production capacity, but the advantage is that it can be built quickly."

Wang Yi smiled. That was the truth.

For example, TSMC's wafer factory has a monthly production capacity of 200,000 to 300,000 wafers. It takes more than a year to build and one and a half years to be put into production.

The monthly production capacity of the Xingyi wafer factory is only 2.5 wafers, which is only one-tenth of TSMC, so it was naturally built quickly.

Moreover, the entire Xingyi wafer factory is divided into three factories. The one being delivered now is only the smallest factory No. 5000, with a monthly production capacity of only pieces. It is the smallest in scale and is built day and night, so it is naturally the fastest.

As for Plant No. 1 and Plant No. , their monthly production capacity is pieces each. They are still under construction and will be delivered in the second half of the year and the end of the year.

Of course, what was delivered was only the basic factory building, and it was just the beginning.

The subsequent equipment needs to be brought in, the production line needs to be assembled, debugged, and trial-produced...

After the trial production is successful, we must continue to optimize and improve the yield rate...

If the yield rate is low, mass production will not be possible, and you will definitely lose money.

Only when the yield rate reaches the standard can the wafer fab be officially put into production.

From the start of construction to the start of production, a large-scale wafer factory with a monthly production capacity of 100,000 or even hundreds of thousands of wafers takes one and a half years.

However, Xingyi wafer factory is small in scale and production capacity. If everything goes well, it will take a little more than a year.

"Chairman, it will take another three months for the subsequent equipment to enter and debug the No. 40 small plant. We expect to be able to verify and trial-produce the 40-nanometer process we designed in July or August. Once the trial production is successful, it will take a few more months to optimize and improve the yield rate. If everything goes well and the yield rate meets the standard, we can officially go into production and mass-produce -nanometer chips by the end of the year!"

Mr. Hu smiled and said, “But Plant No. 2 and Plant No. 3 will be put into production next year.”

"Good, very good!" Wang Yi couldn't suppress his excitement!

One step closer to self-production of chips!

Originally, Wang Yi didn't want to build a wafer factory for self-research and production.

But there is no way, SMIC is really not strong enough.

Wang Yi was afraid of being blocked, so he had to come by himself.

Although this wafer factory is small in scale and its total production capacity is only 2.5 pieces per month, it is sufficient for Xingyi Technology to use it itself for the time being.

Mobile phone chips are relatively complex. A 12-inch wafer can cut out 700 mobile phone chips. Taking into account the yield rate, based on an 80% yield rate, that means 560 mobile phone chips.

2.5 pieces per month means 1400 million mobile phone chips, and 1.68 million mobile phone chips per year, which is enough for Xingyi mobile phones for the time being.

As for low-end smart home chips, they are not valuable and there is no need to take up valuable production capacity, so they can be directly outsourced to SMIC.

In the past, Xiaomi’s smart home chip was sold for only ten yuan each.

Xingyi Semiconductor develops and produces its own products and can sell one chip for one yuan.

Even if it is outsourced to SMIC, the cost is only around 1.2 yuan, a difference of just a few cents.

Xingyi Wafer Factory has limited production capacity, so it is better to produce high-value mobile phone chips.

Mr. Hu looked into the distance and said, "Chairman, the building under construction to the north is Plant 2 of Xingyi Wafer Factory, and further north is Plant , both of which have a monthly production capacity of wafers!"

Wang Yi nodded: "Mr. Hu, the No. 2 and No. 3 plants are still under construction. Will this affect the research and development and trial production of the No. 1 small plant?"

Mr. Hu waved his hand and said, "Chairman, don't worry, we have considered it all. The wafer factory is designed to withstand a magnitude 7 earthquake, so earthquakes below magnitude 7 are not a problem. Even if it is a magnitude 7.5 earthquake, it will only be a temporary shutdown, and there will not be much impact."

"Besides, the three factories are far apart from each other, and the foundations were built together and have been completed long ago. Now it's just the factory construction, so there won't be much vibration. Right now, the equipment in Factory 7 is being put into operation, and it will take time to debug. By the time the trial production starts in three months, Factory will have been capped, so there won't be any impact. As for Factory , it's on the north side of Factory , so there won't be any impact. Besides, we have a -level earthquake resistance system."

Wang Yi suddenly realized, that's what it was.

With a 7-level earthquake resistance, the impact is really not that big.

"Mr. Hu, the 40-nanometer process is now in your hands. Assemble and debug the production line as soon as possible and start trial production as soon as possible. I hope that the 40-nanometer process can be put into production before the end of this year or early next year. By then, our self-developed 40-nanometer Kunpeng 500 SOC will be self-developed and self-produced!"

Although Kunpeng 500 uses a 40nm process, it has an integrated baseband.

虽然比不了下半年高通28纳米的四核旗舰APQ 8064，但比起Xphone 1pro用的英伟达40纳米四核旗舰芯片tegra 3，强大得多。

In September this year, the second generation of Xingyi, equipped with Qualcomm's 28nm quad-core flagship APQ 8064, was launched strongly, and Xphone 1pro will continue to be sold at the beginning of next year.

However, the processor was completely replaced from NVIDIA Integration 3 to the self-developed and produced Kunpeng 500 SOC.

Similarly, the Xingyi Tablet X1pro will continue to be sold next year, and will also be fully replaced from NVIDIA Tegra 3 to Kunpeng 500.

The same is true for Xingyi TV X40 and X50.

In addition, the 999 borderless mobile phone is equipped with Kunpeng 500 SOC as standard. In this way, even if 1.68 million Kunpeng 500s are mass-produced next year, they can be fully absorbed.

"Don't worry, Chairman. I will lead my team to make every effort to achieve mass production of 40 nanometers by the end of the year!"

"Okay, Mr. Hu, I believe in your ability!" Wang Yi smiled slightly.

Mr. Hu didn’t feel much pressure when working on 28 nanometers, let alone 40 nanometers!

To put it bluntly, mature process technologies such as 40 nanometers are what Mr. Hu has left over.

"By the way, Mr. Wang, as you mentioned before, we should hire more people and divide them into two groups. One group will tackle the 40-nanometer process, and the other group will directly start the 28-nanometer process research and development. I am also pushing forward this matter and have hired some strong engineers, but the cost is also very high, after all, we have to set up two R&D teams at once! The salaries of all of us are very high."

In 2012, 5000 to 10000 mobile phone R&D personnel were enough.

But chip R&D personnel and semiconductor process R&D personnel are much more powerful, with a starting salary of at least 10,000 or 20,000 yuan.
