The irony is that all the semiconductor policies that the United States is taking will hurt Taiwan on the long run, because if the electronically advanced countries are creating semiconductors fabs for "domestic consumption", who is going to buy the chips that Taiwan produces? The Chinese? So the U.S. brilliant strategy is to make Taiwan more economically dependent on China? If so, better for China.

An excerpt from the article:
As the saying goes, "Workers want to do good things,We must first sharpen our tools". If the domestic chip manufacturing industry is to be expanded, then domestic chip manufacturing equipment must be the first to break through. China has achieved new breakthroughs in key chip manufacturing equipment.
It is understood that Tsinghua University announced the new results of Professor Lu Xinchun’s team: , the first 12-inch ultra-precision wafer thinning machine Versatile developed by Huahai Zero2IPO -GP300 is mass produced and shipped, and has been supplied to a leading chip manufacturer in China.
A complete chip production line requires the simultaneous cooperation of more than 100 equipment, and the lithography machine is only in the previous process The 12-inch ultra-precision wafer thinning machine is also a key equipment in the field of chip manufacturing and packaging.
Because of the high complexity of this equipment, the difficult technical research, and the high barriers to entry in the market, the long-term Controlled by foreign manufacturers, the domestic market is heavily dependent on imports.
With the efforts of the Tsinghua University Road Xinchun team, the 12-inch ultra-precision wafer thinning machine Versatile-GP300 issued by Huahaiqing Scientific Research has three major features.
First of all, the Versatile-GP300 can provide multiple functional configurations such as precision grinding, polishing, and post-cleaning.It can meet the needs of ultra-precision wafer thinning processes in the field of chip manufacturing and packaging manufacturing.
Secondly, the process pioneered by Versatile-GP300 can not only realize the ultra-flat thinning and surface damage control of the wafer, but also take into account the high efficiency and comprehensive cost performance, which is more suitable for the needs of the domestic wafer thinning market.
Finally, Versatile-GP300 has the advantages of high rigidity, high precision and flexible process development, and its main technical indicators have reached the international advanced level. At the same time, it fills the gap in the field of ultra-precision thinning technology in the domestic chip equipment industry.
Although compared with foreign giants that have developed for decades, my country’s chip manufacturing equipment industry is like a toddler. However, under the leadership of a large number of people with lofty ideals, my country's chip manufacturing equipment industry is removing the "blockers" one by one. The future of domestic chips can be expected, and the future of China's technology industry can be expected!

Some developement with China EUV. The optic system in EUV is using reflective mirror made of multilayers of Mo and Si with layer width in the range of 2nm.
There's news that kyvac capable of coating in the range of 0.1nm.
xw.qq.com
并且中科科美研究的透镜镀膜技术，完成了光学零件0.1nm的镀膜设备。这项技术，满足了大部分物理镜头对膜层制造的需求，同时还能用于光刻机的镜头装备中，
再加上中科院正在安装的光源设备，让我国芯片行业取得了巨大成就。据统计，到6月底，中科院的安装项目已经完成了70%。
Seems like the EUV light source is not based on LPP or DPP but based on synchrotron ,

The reason i say maybe not LPP is I have not seem CO2 gas laser capable of greater than 40kW in China. DPP is underpower right now. So that left 同步辐射光源

Chinese operators roll out Huawei MetaAAU for 5G Network
SHAILAJA PAI 26 NOVEMBER 2021
Three Chinese operators have deployed Huawei MetaAAU — a comprehensive 5G solution — in Beijing, Hangzhou, Shanghai, and Xiamen.
The solution was released in October and Huawei says it is the ideal solution to improve both network performance and energy efficiency using innovative hardware and software, said a press release.
To date, over 1.5 million 5G base stations have been deployed globally, and 176 commercial 5G networks are providing 5G services to more than 520 million users. The 5G device ecosystem is also maturing quickly. More than 1,000 5G devices have been released worldwide, including mobile phones, home CPEs, and industrial modules.
This fast growth of 5G is changing user requirements — demanding a better, uninterrupted experience. At the same time, the push toward carbon neutrality is putting pressure on the mobile communications industry to go green, which in turn calls for more environmentally-friendly products and solutions.
According to the press release, Huawei's 64T64R MetaAAU is the ideal solution to improve both network performance and energy efficiency using innovative hardware and software. For hardware, MetaAAU introduces the extremely large antenna array (ELAA) which enables 384 antenna elements, double that of a conventional AAU (192).
ELAA is combined with ultra-light integrated array and signal direct injection feeding (SDIF) to improve both coverage and integration, it said.
For software, MetaAAU utilizes the Adaptive High Resolution (AHR) Turbo algorithm to enable precise, dynamic, and targeted beamforming, significantly improving user experience and cell capacity. This hardware/software combo marks a breakthrough in Massive MIMO coverage and energy efficiency, the release said.
Huawei’s HarmonyOS Ready for Europe, and 5G Chips on Track for a Comeback

HarmonyOS, Huawei’s distributed operating system, will be launched in Europe next year, according to Derek Yu, the president of Huawei’s Consumer Business in Central & Eastern Europe, Northern Europe and Canada.
The latest estimation indicates that 150 million devices are already carrying HarmonyOS. By the end of 2021, the number will jump to 200 million. Huawei aims to boost the number of HarmonyOS-carrying devices to above 300 million: while 200 million of them will be Huawei products, the remaining 100 million devices will come from partners in Huawei’s ecosystem. Within China alone, already 135 types of devices are running HarmonyOS.
At the Huawei Developer Conference 2021 held in October, a developer preview version of HarmonyOS 3.0 was just unveiled. According to Tim Gong, the president of software at the Huawei Consumer Business Group, the first quarter of 2022 will see the official launch of HarmonyOS 3.0 beta.
5G RF filters still China’s missing puzzles
Confirming earlier speculation that Huawei would soon re-introduce its 5G chips, Derek Yu revealed that Huawei’s Shanghai R&D center had been indeed working on the design of a 5G chip, and hinted the possibility of ending foreign dependency on 5G chips.
Owing to U.S. export restrictions, Yu reiterated that Huawei could only obtain 4G chips now, and cooperations with companies like Qualcomm would continue to ensure a stable supply.
Huawei’s in-house 5G processors, Kirin 9000, are soon out of stock, and Qualcomm’s 5G-disabled version of Snapdragon 888 chipsets have come to replace Kirin 9000 in some phone models, such as the P50 series launched in early August. Ironically, even the said Kirin 9000 chips lack 5G connectivity.
As the world’s first 5nm-manufactured 5G chipset, Kirin 9000 relied on TSMC’s process technology. However, due to U.S. sanctions, TSMC has already stopped making the chips for Huawei since September 2020. It was speculated hat Huawei had ordered 15 million Kirin 9000 chips from TSMC before the restriction took effect, but received approximately 8.8 million chips in the end. The act also indirectly triggered the global chip crisis.
Even with the stockpile, key RF frontend components are still dominated by U.S. and Japanese suppliers, rendering Kirin 9000 unable to support 5G. Broadcom, for example, dominate the Bulk Acoustic Wave (BAW) filters market, followed by Qorvo. Similarly, the Surface Acoustic Wave (SAW) filter market is dominated by Japan’s Murata Manufacturing Co. and TDK Corp.
Despite Huawei’s optimistic announcement, it is unclear how the RF component issues are to be addressed. Details are also lacking regarding which process node the prospective 5G chips will use.

Look at the word play: 央视！EUV! Equipment! 0.1nm!
History repeats itself, first time as a tragedy, second time as a farce.
This is most definitely farce material.
Today, the Americans ban other Americans from investing into Chinese companies.
Tomorrow, the Americans will bitterly complain to the Chinese for further market access and demand that Americans can invest anywhere they want inside China.
How many times was Huawei banned again?
