if CXMT want to expand the should consider using as much domestic tools as possible and find alternatives for US technology just in case.
2 Billion Dollars is a lot money especially in Mainland China. without minimum guarantee from domestic suppliers, CXMT would never plan for expansions. government also involves. it means they get green signal from local suppliers.

its actually a good news.

JCET sees growth accelerate in 3Q23​


JCET posted net profit of CNY0.48 billion in the third quarter, up 24% on quarter.
According to JCET, the company has focused on key advanced packaging applications this year, continuously improving its overall solution capabilities for application scenarios, optimizing production capacity layout, and further strengthening its position in the global IC packaging and test industry.
JCET has made significant strides in a number of industries, including wide bandgap power devices, high-performance computing (HPC), 5G communications, and automotive electronics. With the market for electric vehicles, for example, quickly developing, JCET has been able to capitalize on market prospects, the China-based OSAT indicated.
During the first three quarters of 2023, JCET's sales from the automotive electronics sector soared by 88% year on year, according to the company. By providing R&D and HVM services to clients worldwide, the OSAT has further strengthened its leadership position in areas such as radio frequency front end modules, RF power amplifiers, and antenna in package (AiP) modules in the 5G communications sector, it continued.
JCET stated that the company is stepping up its efforts with customers in the AI and HPC domains for advanced packaging solution development and product introductions, accelerating market expansion in high-computation systems, power management, high-performance storage, and smart terminals by leveraging high-density heterogeneous SiP technologies and advantageous global manufacturing layouts.
In the power semiconductor market, JCET's high-density integration solutions for wide bandgap power devices, developed in conjunction with global customers, are widely used in automotive and industrial energy storage, the OSAT said.
JCET is committed to developing technical innovation, investing CNY1.08 billion in R&D in the first three quarters of 2023, a 10.4% increase year on year, according to the OSAT. The company continues to promote the construction of high-performance package manufacturing facilities, as well as the conversion of existing factories to advanced packaging technologies.
In addition, by enhancing inventory control and supply chain management, JCET guarantees the continued high efficiency of its operations, it claimed.
"In recent years, JCET, by focusing on high-performance advanced packaging technologies, has made breakthrough progress in collaboration with major customers on the high-end chip business and achieved significant quarter-on-quarter growth in performance for the third quarter of this year," said company CEO Li Zheng in a statement. "The company will seize new opportunities arising from the restructuring of the global industrial chain and will continue to promote the healthy development of IC back-end manufacturing."

On just how hard it is to certify to the highest standard of auto grade. We have SemiDrive here taking basically a year and half here (from its launch on April 2022) for its E3 MCU to getting TUV ASIL-D certifcate in September. It is still the only one of its series to getting ISIL-D. The other chips that got launched about the same time reached ASIL-B, quite possibly you don't need to reach ASIL-D for central computation platform

also reached AEC-Q100 grade 1 level certification. Any the prize of that is a lot of customers.

Recently, was first domestic MCU to be on a active suspension (CDC damper controller) that will go on Chery Exeed & Tiggo 9 cars

Pretty good domestic producers of various components can all use this now

At same time, they came out with X9SP smart cockpit SoC and V9P ADAS SoC in April as part of their SCCA2.0 central computation platform

This is good news, domestic chipmakers moving up value chain

对于汽车芯片而言,如果没有高中低端各系列完整的产品布局,车企很难选择这样的芯片。与手机不同,汽车只做低端芯片无法长久在行业立足,而且面对宝贵的时间窗口,只有已经有大规模量产的芯片公司才能抓住机遇
can't just go for low end or hard to stay in the game. So very critical to have these national champions that can compete with ST/Infineon/TI

And the great thing about domestic MCU is that they end up using domestic memory controller too like this

And semidrive now has many customers with it's product

目前,芯驰科技已通过AEC-Q100可靠性认证、德国莱茵ISO 26262 ASIL D功能安全流程认证、德国莱茵ISO 26262 ASIL B和ASIL D功能安全产品认证以及国密商密认证,是国内首个完成“四证合一”的车规芯片企业。

目前,芯驰已经拥有近200个定点项目,服务超过260家客户,覆盖国内90%以上主机厂及部分国际主流车企,包括上汽、奇瑞、长安、东风、一汽、日产、本田、大众、理想等,出货量超三百万片。

在演讲的最后,陈蜀杰透露,目前已经有国际主流车厂在跟芯驰做平台级的联合研发,后续将有更多的量产案例跟大家分享,芯驰的产品将更加迅速的从中国不断走向世界。

Zhixin Semiconductor is the first to use SMIC's 40nm auto grade process for producing MCUs

Z10K11XN系列产品的推出是一个起点,智芯半导体将继续完善基于SMIC 车规40nm的产品线布局,覆盖从32pin至512pin的封装,从单核到多核CPU,功能安全最高可满足ASIL-D,覆盖新能源汽车电池管理BMS、整车控制VCU、车身域控、底盘EPS/Brake/Suspension和动力域控应用等。
covers 32 to 512 pin (single to multi-core CPU), can satisfy ASIL-D certification and be used for BMS, VCU, BCM, chassis EPS/brake/suspension/motor (so the most stringent area of MCU)

To me, this seems like a huge step up for SMIC. Being able to fab 40nm auto-grade MCU opens up a much larger section of the MCU customer base for SMIC.

Similarly, if it can get to 28nm next, that will be even bigger

I look at the various auto SoC & ADAS chips by numerous domestic players and they all use 16nm or 8nm or even 7nm process. Now, while I'm sure the auto grade standard for SoC in a central computation unit has less stringent standard than something like brakes, but it still must pass certain standards, which I'm not sure if SMIC is fully there yet (no idea what it is doing with HW auto chips). But either way, this is a confirmation that SMIC is finally covering most of the 40nm space now. It seems to me ASIL-D grade auto chips was always one of the hardest to achieve

This is interesting. At 48:35,they interviewed "SND group". According to the company representative,they were a Russian startup,make some kind of special PCB materials. But they couldn't get any investment from Russian investors,then they went to China and successfully find investors. They now have factory in China producing this material for Chinese customers,as well as importing it to Russia. She says that Huawei and ZTE are their customers. She says the problem of producing these stuff in Russia in general,is the lack of access to hardware and equipments.

I saw the video. It is a replacement for conventional soldering. You put a sheet of the material between the base and the chip you want to solder, and then use electricity to activate the material. She does a demo of it at 59:18. She claims the advantage is it is faster and cheaper than conventional soldering.

Interesting stuff here about SemiDrive using TSMC's 22nm process for its MCU, but that 22nm does not have mature auto grade flash process, so it uses logic process, but need XIP outside flash
Does anyone know how this works in practice with respect to this XIP flash?
然而,目前22nm目前还没有成熟的车规嵌入式Flash工艺,因此芯驰采用的是Logic工艺,需要XIP外部Flash

针对XIP Flash和eFlash在带宽,功耗,功能安全,可靠性方面的区别,可回头分享一篇文章;

22nm制程高,因此可以带来的计算能力会强,如芯驰E3600的主频可以到600MHz;

Yes. I would say there is no lack of talented people in Russia and many other developing countries. It's just that the environment for developing technology/large scale industrial projects or convert ideas to actual merchandise does not exist, so these talent pool tend to flee to other places.

You cannot make embedded Flash at those scales, since you cannot shrink Flash memory cells to such a degree, but you can use embedded MRAM or ReRAM which serves the same purpose.

its actually a good news.
2 billion usd is from center government state fund. Total investment is 6 billion usd.
