Confirming the theoretical foundation of steady-state microbunching.​

Steady-State Microbunching (SSMB) has been proposed as a concept to generate coherent synchrotron radiation at an electron storage ring. SSMB promises to supply kilowatt level average power radiation in the extreme ultraviolet regime, meeting the power level demands for lithography applications that presently cannot be fulfilled by established accelerator technologies. SSMB is under theoretical and experimental study, building on a proof-of-principle (PoP) experiment at the Metrology Light Source which previously showed the viability of the idea. Here we report experimental findings from systematic studies in the ongoing SSMB PoP experiment, where microbunching is generated from an energy modulation imposed by a laser of wavelength 1064 nm. The results confirm the expected dependence of the microbunching process on modulation amplitude and show that the influence of transverse-longitudinal coupling dynamics is as predicted. This confirmation of key parts of the SSMB theory establishes a solid footing for continuing the proof-of-principle efforts towards the goal of constructing a prototype SSMB light source facility.

Meanwhile, preparations for the next phase of the SSMB PoP experiment are ongoing. The laser system that will provide turn-by-turn modulation is completed and is undergoing final commissioning and tests before installation at the MLS will proceed. Integration of the new laser is planned in parallel to the existing laser system, also allowing single shot modulation experiments to continue.

Interesting, so experiments are still being done in Germany.

Looks like between Shanghai and Germany. My guess once they find it works the Germans will try to power ASML machines with it.

Hmmmm...its very telling that even after US sanctions most Chinese companies still want to stick with American products like Ndivia. There must be a reason for such a weird obsession (decision) I guess?
Seems Huawei is lucky the US is stopping Chinese companies from buying US chips, that way Huawei can finally dominate the Chinese AI chip market with its Ascend chips.

Ever heard of CUDA?

it does not seem like it. tsingwah is designing a version the machine that will repeat it million of times.

The reason is that Nvidia products are good. They work, and work well. Also there is no alternative available for many of those companies, so either you stick with Nvidia or you have nothing.

Huawei simply doesn't have enough chips to replace Nvidia across the board. Not enough capacity to meet demand. That is changing, but it will take time.

Shengmei Shanghai and Aisen Co., Ltd. have carried out strategic cooperation in process materials and equipment in the fields of wafer manufacturing​

According to information from Aisen Holdings, recently, Shengmei Shanghai and Aisen Holdings have been actively carrying out strategic cooperation in process materials and equipment in the fields of wafer manufacturing and so on.

Both Shengmei Shanghai and Aisen Co., Ltd. adhere to the development strategy of differentiated competition and innovation. With advanced technology and rich product lines, they have developed into a few domestic semiconductor equipment and semiconductor special materials providers with international competitiveness. Their products have been recognized by many mainstream semiconductor manufacturers at home and abroad and have gained a good market reputation. The integration of the advantages of both parties will also lay a solid foundation for cooperation.

Recently, Aisen Co., Ltd. announced that it plans to invest in the construction of the Aisen Integrated Circuit Material Manufacturing Base Project in Kunshan City. The total planned area of the project is about 50 mu, and the total investment is expected to be no less than 500 million yuan. The announcement shows that the base's products include semiconductor photoresists, electroplating solutions, photoresist resins, high-purity reagents, etc., and the total annual output value is expected to be no less than 800 million yuan after reaching full production.

Why is the SA800 not listed on the SMEE websites product section.

Looks like the don't want attention for now, but they give a hint in their website.

Looks like Pengcheng Laboratory in Shenzhen is working toward EUV and also the Institute of Advance Science Facilities in Shenzhen is seems to be working on FEL EUV according to some sources.

Here is another FEL EUV in Chengdu by CAEP specifically for litho
