Please, Log in or Register to view URLs content!
The ongoing investigation is examining whether TSMC has been engaged in the production of AI chips designed by Huawei, according to the report. These AI server chips have gained popularity among Chinese customers as an alternative to NVIDIA’s chips, which they are barred from purchasing due to U.S. export regulations.
Additionally, the inquiry is said to be exploring whether TSMC manufactured smartphone chips for Huawei’s devices as well. The Information notes that Huawei’s Mate 60 series, featuring a processor made in China by SMIC, was a potential target of investigation.

Oriental Crystal Source PanGen platform adds a new member, PanOVL, the marking optimization tool, is launched​


When the semiconductor manufacturing process evolves to the 22nm node and below, with the introduction of multiple patterning technology, the requirements for overlay errors between different process layers become increasingly higher. Overlay measurement technology can be divided into image plane image recognition measurement technology and diffraction-based DBO (Diffraction Based Overlay) measurement technology. Compared with the image recognition-based method, diffraction-based overlay error measurement has better measurement result repeatability, lower device-induced measurement error TIS (Tool Introduced Shift), and can adapt to smaller feature sizes. It has become a widely used overlay measurement method for large-scale integrated circuits at the 22nm and below process technology nodes.

In order to measure the overlay error, a specific overlay mark needs to be specially designed on the wafer. The performance of the overlay error device measurement depends largely on the design of the overlay mark. The DBO overlay mark optimization tool based on computational lithography can simulate the key indicators of overlay error measurement, so that a better overlay mark design scheme can be given based on the simulation results, thereby shortening the mark development cycle and improving the efficiency and quality of the entire lithography process.

Based on the solid computational lithography platform PanGen®, Oriental Crystal Source launched the DBO overlay mark simulation optimization product PanOVL, which can simulate the overlay mark from multiple key indicator dimensions. At the same time, considering the application scenario of large-scale simulation of massive overlay marks, PanOVL introduced a distributed computing framework, which greatly accelerated the efficiency of finding better overlay marks through simulation.

Oriental Crystal Source's PanOVL software uses the PanGen OPC ® engine and the PanGen Sim ® rigorous electromagnetic field simulation engine, with the help of the GPU+CPU hybrid computing platform and the PanGen ® distributed computing framework, to perform large-scale overlay mark simulation, and integrate the simulation results of multiple dimensions to select the overlay mark scheme with better performance for actual lithography.
PanOVL can identify overlay marks with a large process window, give overlay marks that meet good signal-to-noise ratios and have stronger detection signal resistance to process disturbances, and can also simulate the impact of exposure process aberrations on overlay marks, providing overlay marks that make overlay measurement results more in line with the actual device situation.

I believe Russia is also increasingly producing more and more Helium from its massive LNG field, the US is far from dominating helium production currently. Qatar is producing more

.
Those stats are from when the Russians had like 1 train out of 6 total planned operational at the Amur Gas Processing Plant.

Anyone have more knowledge about this? Can China somehow convert this Arm China a completely Chinese company? If so, does it mean it will "own" Arm v9 ISA too? It will be amazing considering how many billions of devices have Arm ISA embedded in then
The whole idea of ARM China was precisely to insulate Chinese companies from Western sanctions. ARM China was supposed to get irrevocable licenses to ARM IP. Which it then would sublicense to Chinese companies.

I kind of doubt it is possible to license ARM v9 to China. Because of SVE. The US put explicit clauses where chips or technologies that use vector units above a certain bit size aren't allowed to be sold or licensed to either China or Russia.

It has been posted here multiple times, public statements made by ARM itself, that ARM technology is not of US origin and they are free to license v9 to china. The small core in Huawei's Kirin 9000s is a v9 core from ARM.

These might convince you ... and many similar articles about it since 2021

Multiple patterning bi-line/tri-line structure at limiting resolution for 7 nm by negative tone development of ArF immersion lithography​


Abstract​

Since the advanced Integrated Circuit (IC) manufacturing process has reached the 14 nm technology node and beyond, the pattern size of integrated circuits has become much smaller than the theoretical minimum resolution of lithography. In order to further extend the performance of immersion lithography, the industry introduces Multiple Patterning Technology (MPT) and Negative Tone Development (NTD) lithography technology. MPT and NTD lithography have greatly improved the process window of immersion lithography, enabling ArF immersion lithography to extend to 7 nm or even 5 nm technology nodes and below. However, MPT still has limited ability to improve the process window for some special patterns. For example,for the poly gate process in Front End of Line (FEOL) or the metal routing process in Back End of Line (BEOL), IC design often uses a special kind of patterns, such as the bi-line or tri-line structures. Due to the fact that some type of the bi-line/tri-line structures have a semi-dense pattern on each side, the process window of these patterns are relatively narrow, making them difficult to manufacture. This paper focuses on the patterning technology scheme of bi-line/tri-line structures in IC design under the diffraction limit of 193 nm immersion lithography. This paper explores the solution for bi-line/tri-line patterns through mask split strategy and NTD lithography process simulation with a physical model, including illumination conditions, Optical Proximity Correction (OPC) methods, and photoresist process parameter design. This study provides a reference scheme for subsequent NTD process development and patterning technology, as well as a reference idea for IC design methods.​

Continuing from where I left off,

"One of the main products of the Amur GPP is helium, a particularly sought-after element for high-tech industries. With an annual output of 60 million cubic meters, the GPP is poised to become the global leader in helium production. The key link in the logistics chain of helium supplies to the international market will be the helium HUB near Vladivostok, which is going to be put in operation in the nearest future."

That would make the Russians tied with Qatar for helium production in 2023. I have also heard of other proposed helium capture operations in Russia. But those are pretty far away from being into construction yet.

It has been posted here multiple times, public statements made by ARM itself, that ARM technology is not of US origin and they are free to license v9 to china. The small core in Huawei's Kirin 9000s is a v9 core from ARM.

"Instruction set: ARMv8.2-A"

Notice how it has NEON but not SVE.

"Each core features a single 128-bit NEON unit. It is capable of executing single double-precision FMA vector instruction per cycle or two single-precision vector instructions per cycle. Operating at 2 GHz, a 64-core chip will have a peak compute of 512 GigaFLOPS of double-precision floating point. It's worth noting that compared to the TaiShan v100, the throughput for single-precision vector has been doubled from 1 to 2 instructions per cycle."

So only 128-bit wide vector instructions.

They could also have cut SVE support for die space reasons. But it seems they currently do not have it.
