I repeat myself.
U.S. products are unreliable and U.S. companies are unreliable partners. Chinese companies put themselves and their investors at risk by buying U.S. products. And this is with Biden, with Trump in 2025 is going to be much much worse. The de-Americanization of commercial products is the only way forward for Chinese companies. Chinese companies should invest within China in companies that offer alternative products.

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?

:p
That was sour grapes to try and damper the listing. Sensetime was put on the so called entity list but it has shrugged it off and continues to grow.

The US will continue to target China's leading companies in current and future foundational technologies.

The United States government should definitely stop trying to suppress Chinese companies.

The United States credibility is on the line.

When it does not work and people do not listen, that means when it comes to China, the United States is impotent.

Impotency is no joke, but other people laugh anyways.

I hope the U.S. and all their allies will do us a favour again, for banning the 6G Technology. The stupid decision is only hurting american tech companies and their economy.
The gap between the west and China in using 5G is already huge and it becomes wider. In China they already got smart factories and some cities will become a smart city.
Therefor China will dominates over all the patents in the 5G application/software field.

US planning for complete export ban to SMIC for key technologies
Please, Log in or Register to view URLs content!
close regulatory loopholes that have allowed Semiconductor Manufacturing International Corp. to purchase critical U.S. technology, the people said. SMIC, as the company is known, has been able to continue buying U.S. tools to make chips despite its inclusion on the Commerce Department’s entity list, which is designed to limit access to key U.S. exports.
The Defense Department, with the support of officials at the State and Energy Departments, as well as the National Security Council, wants to change the wording to restrict SMIC’s access to items “capable of” producing semiconductors with 14-nanometer circuits and smaller, the people familiar said, broadening the list of items SMIC won’t be able to get

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.

央视正式宣布:EUV技术大获突破!0.1nm设备已投入使用,在美国的限制下,ASML没办法向中国提供高端的EUV光刻机,但我国也不是会轻言放弃的。就在最近,央视正式发布消息,我国不仅在EUV光刻机上取得突破,还将光源0.1nm的设备投入使用。美国阻止ASML……

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 ,
高能同步辐射光源 you can check with WTAN ,

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
Hello Ansy
Send my greetings to Oldschool.

I believe that China is very serious about developing EUVL and they are researching different methods in coming up with powerful Light Sources.

They are certainly working on a LPP Light Source and Shanghai Inst is trying to achieve at least 30Kw MOPA C02 Laser output. You will hear more about this when they have suceeded in achieving the power output necessary.

The next method is using a Synchtron Light Source or SSMB. Tsinghua University is leading this project and a SSMB Storage Ring Facility in Beijing is now in the planning stage. Construction could start very soon.

I have also heard that the Chinese Academy of Sciences has also started to involve themselves in Synchrotron Light Source development for EUV Lithography.
OldSchools Report states that Chinese Academy has developed Synchrotron Radiation Light Source Equipment which has been installed on the 28th June at the newly built Beijing Synchrotron Facility. The facility is 70% complete. According to the Report, this equipment can supposedly be used as the Light Source for a Chinese EUVL. Exactly what type of equipment installed is unknown.

More news hopefully can come out about this equipment developed by CAS.

AMEC Surpasses 100-Chamber Order Milestone for its Prismo UniMax® MOCVD System

Advanced Micro-Fabrication Equipment Inc. China (AMEC, stock code 688012), today reported that orders for its Prismo UniMax® system now exceed 100 chambers, marking a new milestone for its MOCVD business. The tool is used to mass-produce gallium nitride-based (GaN) mini-LEDs found in TVs, laptops, monitors, automotive displays, outdoor displays, and other products.

Customers adopted the tool for its excellent wavelength uniformity, energy efficiency, and high production throughput, as well as AMEC’s expert local field support and customer service. More than 100 chambers have been ordered since the tool’s official launch in June of this year. The momentum reinforces AMEC’s leadership in the MOCVD market.
The Prismo UniMax system is engineered for high performance mini-LED production. Several proprietary features combine to deliver superior wavelength uniformity, repeatability, and production stability. They include a heating system design with heating elements in each chamber that control local-area temperatures and distribute heat precisely as required across the wafer surface during the MQW growth period. This AMEC innovation helps maximize uniformity. Other key features include an optimized showerhead, as well as a new-generation power supply unit that increases energy efficiency, and a large 785mm-diameter susceptor that drives higher throughput and reduces overall costs.
In addition to its performance benefits, the UniMax system achieved fast market acceptance for its manufacturing flexibility. Each tool can contain up to four independently controlled chambers, and process as many as 164 four-inch or 72 six-inch wafers simultaneously with a simple susceptor configuration adjustment -- an industry-leading capacity for a tool of this kind.
The system is the newest addition to AMEC’s MOCVD product family that includes the Prismo D-BLUE®, the Prismo A7® and the Prismo HiT3® systems. When it debuted in 2013, the Prismo D-BLUE was the industry’s first MOCVD system innovated, developed, and manufactured in China. The Prismo A7® and the Prismo HiT3® were successfully launched after that. Today, AMEC MOCVD tools are installed in every major LED mass-production fab.
The swift adoption of the UniMax system is thanks to AMEC’s continuous MOCVD equipment and process innovation, and close alignment with manufacturing leaders, noted Dr. Zhiyou Du, Executive Vice President & COO at AMEC. “As customers migrate to applications like mini-LEDs, we are proud to address their mass-production imperatives with competitive technology solutions. The 100-chamber order milestone validates the performance advantages of our Prismo MOCVD platform and the trusted expertise we bring to our customer partnerships,” he said.
