Sanying Precision Control successfully applied for the Tianjin Beijing-Tianjin-Hebei Science and Technology Achievement Transformation Project and conducted research and development of ultra-precision displacement capacitance sensors
Sanying Precision Control has actively responded to the call of "Beijing-Tianjin-Hebei Integration" and "Made in China 2025" by introducing foreign talents and technologies, and jointly developed ultra-precision displacement capacitive sensors to achieve ultra-precision displacement measurement and acquisition, which is the key to the improvement of manufacturing equipment. At present, domestic technology in this area lags far behind the international advanced level. The research and development of this project has reached the international advanced level, established its own national brand, participated in international competition, and provided strong support for the development of the country's high-end equipment industry. The Tianjin Science and Technology Commission has funded 500,000 yuan for this purpose to encourage corporate scientific research projects.
Thin Ice: US Pathways to Regulating China-Sourced Legacy Chips
May 13, 2024We take a fresh look at the data on the expanding capacity of China’s legacy chip production after two big waves of US-led chip controls and review how the US aims to target these foundational chips.
More FEL EUV lithography from Shanghai.
Proposal for an extreme ultraviolet free-electron laser with low-energy electron beam.
Description
There is an increasing demand for coherent extreme ultraviolet (EUV) radiation in imaging and spectroscopy, particularly as the next generation of EUV lithography requires high-power EUV light sources. Experimental results demonstrate that harmonic lasing in a free-electron laser (FEL) is an effective method for extending the wavelength range and producing narrow bandwidth FEL. In this contribution, we propose operating the radiation segment in conventional echo-enabled harmonic generation at high harmonic mode instead of the fundamental radiation. This approach combines phase shifting and undulator tapering to generate high-power EUV radiation. The results indicate that fully coherent EUV radiation with an average power of up to 1 kW can be generated using a 280-MeV electron beam with an average current of 10 mA.
R&D progress of cavity based EUV/X-ray FEL at Shanghai
The development of short-wavelength, fully coherent Free Electron Lasers (FELs) represents a pivotal direction for advancing X-ray source technology. Promising solutions under consideration include cavity-based X-ray Free Electron Lasers (CBXFELs), such as the X-ray Regenerative Amplifier FEL (XRAFEL) and the X-ray FEL Oscillator. We are pursuing the development of advanced FEL schemes and the experimental validation of optical cavity technologies at SARI. This report outlines our progress in the development of CBXFEL for the hard X-ray and Extreme Ultraviolet (EUV) regions. We are currently testing the operation of a rectangular cavity with Bragg-reflecting crystals based on the SSRF. Ringdown of a small 1-meter silicon crystal cavity has been experimented, and preparations for a diamond crystal-based cavity are underway. Concurrently, we have developed a suite of EUV reflective optics utilizing multilayer technologies, aiming to provide high average power with RAFEL mode at a wavelength of 13.5 nm in the future. Additionally, we are advancing the manipulation of CBXFEL performance, including the generation of controlled polarization and Orbital Angular Momentum (OAM).
Another overpaid stooge article, the stooges in question ignore the FACT that China chip capacity increased as a response US unreasonable and chaotic export controls on IT-Electronics companies like Huawei, the D.C. stooge effort of trying to kill Huawei <yes, kill, that is what these DC stooges want> created a lot of panic in China IT-Electronics companies, forcing them to source domestically their components for their products in order to avoid sourcing shocks, that is fact. This stooges should write articles about the people in Washington and their stupidity and not scared Chinese companies, but guess they don't want to talk about their bosses, the revolving door is real.
Another thing that these stooges ignore or omit is that the vast majority of Chips made in China are consume in China, IN FACT, even with the increase capacity I think China produced chips meet 40-45% of the total demand in China, only half.
WHAT THEY SHOULD BE WORRY, is about US legacy IC companies like TI and Microchip, that due D.C. stooge stupidity could see their market share in China reduced as domestic products get more used by big domestic IT-electronics companies like Huawei and others, I mean losing 30% of market share is pretty bad for a company health.

Cry about it!!!!!
Note that Shanghai FAB will automatically use ASML machine while the rest will be going full domestic especially the Beijing FAB.

Is this tidalwave? At least he's moved on from stalking Ren Zhengfei.
The lag effects are very long and so it’s hard to observe outcomes until it’s too late for policymaking.
The argument that the export controls don’t work because they solve a coordination problem within China’s private sector is fundamentally one about time preferences with the classic response that the controls lock China out of downstream markets that utilize semiconductors, and denying China the benefits from trade.
I don’t think there’s per se a “right” answer as much as you have fundamentally different orientations and that results in substantially different policymaking choices.
