Is it viable? Plus even if it suceeds(whicb is another matter altogether) does Russia doesnt have a large enough electronics market to justify such large investment/capital.
Why don't we see more China/Russia coiperation in this area?
Yes is possible, they have good research institutions.
I think their immediate goal is to have an tool ecosystem to make ICs for the military and government projects.
The long term goal is to have an ecosystem of tools for making chips for their country. Given that the internal demand is not huge, they dont need huge fabs like China and TSMC do. Also, like will probably will happen in China, having a domestic ecosystem of tools will allows them to control the cost of building fabs. Maybe because the demand is not high they don't need very high throughput tools lowering the prices of these tools. The monopoly of US-Japan and ASML of semiconductor fabrication tools is one of the reasons for the huge costs.
I do think at the end both ecosystems will intertwined with both buying from each other.
Kilowatt-Level EUV Regenerative Amplifier Free-Electron Laser Enabled by Transverse Gradient Undulator in a Storage Ring.
Abstract
High-average-power extreme ultraviolet (EUV) sources are essential for large-scale nanoscale chip manufacturing, yet commercially available laser-produced plasma sources face challenges in scaling to the kilowatt level. We propose a novel scheme that combines the high repetition rate of a diffraction-limited storage ring with a regenerative amplifier free-electron laser (RAFEL) employing a transverse gradient undulator (TGU). By introducing dispersion in the storage ring, electrons of different energies are directed into corresponding magnetic field strengths of the TGU, thereby satisfying the resonance condition under a large energy spread and increasing the FEL gain. Simulations show that at equilibrium, the average EUV power exceeds 1 kW, with an output pulse energy reaching ∼2.86 μJ, while the energy spread stabilizes at ∼0.45%. These results demonstrate the feasibility of ring-based RAFEL with TGU as a promising route toward kilowatt-level EUV sources.
Cryo-electron tomography reconstructs polymer in liquid film for fab-compatible lithography
Abstract
Liquid film is ubiquitous in nature and serves as the critical medium for the dissolution of photoresist to create nanoscale circuit patterns in lithography, which is a core task since the birth of semiconductor industry. However, despite decades of research, the microscopic behaviors of photoresist in liquid film and at interfaces remain elusive, leading to industrial effort for pattern defect control largely a trial-and-error process. Here, we unravel the nanostructures and dynamics of photoresist polymers in liquid film and at gas-liquid interface using a cryo-electron tomography (cryo-ET) methodology. The native-state three-dimensional structures of photoresist polymers are reconstructed by cryo-ET at significantly improved resolution compared to conventional methods. Cryo-ET reconstructions resolve the spatial distributions of photoresist polymers across gas-liquid interface into bulk solution, revealing the cohesional entanglements between polymer chains. By inhibiting the polymer entanglements and leveraging photoresist’s adsorption at gas-liquid interface, the contaminations across 12 inch wafers have been eliminated under industrial conditions, yielding a > 99% improvement in minimizing the pattern defects for fab-compatible lithography.
New generation BeiDou-3 short message communication SoC chip released
At the recently held 4th Beidou Large-Scale Application International Summit, HGI Beidou released the new generation of Beidou-3 short message communication SoC chip HD6180.
This chip integrates industry-leading technologies and indicators. Through 22nm advanced process, integrated RF transceiver SoC design, enhanced weak signal communication capability, fast signal capture capability, dual-mode decoding capability and long battery life based on ultra-low power technology, it provides industry and mass customers with a more cost-effective and competitive Beidou short message chip-level solution.
In the future, this chip will not only play a more important role in professional fields such as emergency rescue, marine fisheries, industry communications, meteorological data collection, power data collection, and logistics vehicle supervision, but will also be integrated into people's daily lives and appear more frequently in smartphones, smart watches, and smart cars.
According to the information, Beidou short message communication is a unique feature of the Beidou satellite navigation system that distinguishes it from other global satellite navigation systems. In areas without mobile communications or internet coverage, Beidou satellites provide short message communication, enabling two-way communication via satellite text messages. Beidou short message communication effectively complements terrestrial mobile communication networks, meeting the needs of emergency communications, search and rescue, and other services in areas without terrestrial network coverage. As a key component of the national emergency response system, short message communication services have played an increasingly important role in supporting people's livelihoods, disaster relief and mitigation, and field search and rescue in recent years.
