Trump Team Seeks to Toughen Biden’s Chip Controls Over China.

Trump officials recently met with their Japanese and Dutch counterparts about restricting Tokyo Electron Ltd. and ASML Holding NV engineers from maintaining semiconductor gear in China, according to people familiar with the matter. The aim, which was also a priority for Biden, is to see key allies match China curbs the US has placed on American chip-gear companies, including Lam Research Corp., KLA Corp. and Applied Materials Inc.

The meetings come in addition to early discussions in Washington about sanctions on specific Chinese companies, other people said. Some Trump officials also aim to further restrict the type of Nvidia Corp. chips that can be exported to China without a license, Bloomberg News has previously reported. They’re also having early conversations about tightening existing curbs on the quantity of AI chips that can be exported globally without a license, said some of the people, who asked not to be identified because the deliberations are private.

One key measure is blocking Chinese memory chipmaker ChangXin Memory Technologies Inc. from buying American technology, a step that Biden officials seriously considered but ultimately did not pursue due to opposition from Japan.

Some officials on Trump’s team also want to intensify restrictions on Semiconductor Manufacturing International Corp., the main chipmaking partner to Chinese telecom giant Huawei Technologies Co. Biden effectively blocked shipments to some SMIC facilities but established a case-by-case review for others, which the officials worry could allow SMIC to purchase tools that are ultimately used at restricted plants. SMIC’s shares closed down 1.45% in Hong Kong.

Given how down bad the relations between Europe and US are deteriorating, I wouldn't be surprised if they allow ASML to chip EUV machines to China. Also there is the issue that Trump is businessman not a politician, I think that the cries of the industry will have a bigger effect in Trump than lala land Biden. but let see what happens, US stupidity know no bounds so at the end is more domestic market share for Chinese companies.

Not only does ASML depend on key US inputs for its products (e.g. Cymer), but the US also controls the vast majority of its downstream markets via Taiwan and South Korea. The Europeans talk a big game, but will ultimately cave because they are not independent, nor are they going to become independent any time soon. Trump is just an American mask off moment, but the underlying control was always there.

I am speculating, but I have never seen the Europeans so angry like these days, I wouldn't be surprised if the break up with US at least in immersion and more if Trump put tariffs on them. What the US will do? put export controls on ASML? that will kill Intel and Micron.
And any coercion could be met with European export controls to the US. If you think China is dependent on ASML, the US is much much worse. At least China have their own independent scanners and supply chain.

The Europeans have more power in the relationship than they think, the issue is that they are too cucked for far too long to realize that.

The Institute of Microelectronics has made new progress in the research of chiplet thermal simulation tools​

Heterogeneous chip integration has brought a major upgrade to the semiconductor industry and can effectively solve many bottlenecks in chip design and manufacturing. However, while high-density integration reduces the cost of computing chips, it also faces technical challenges such as significantly increased power consumption and heat dissipation difficulties. Thermal management has become a key issue in improving chip performance. How to propose new thermal simulation methods to address the complexity of heterogeneous chip integration has put forward new requirements for chiplet thermal management technology.

In response to the above problems, the multi-physics simulation research group of the EDA Center of the Institute of Microelectronics has built a three-dimensional grid transient heat flow simulation model for chiplet integration, which can realize efficient and accurate simulation of transient heat flow of chiplet integrated chips, and lay a core technical foundation for temperature hotspot detection and temperature sensing layout optimization of chiplet heterogeneous integration. At the same time, the research group has made arrangements in the multi-physics simulation of integrated chip electrothermal force, and carried out research work such as DC voltage drop, thermal stress and wafer warpage simulation.

By performing anisotropic equivalence on redistribution layers (RDL), through silicon vias (TSVs), and bump arrays, a cross-scale anisotropic thermal simulation model from GDS layout to system-level packaging was constructed, which not only improved the accuracy of the simulation model, but also optimized the integrated chip temperature hotspot detection method. At the same time, a core-grain heterogeneous integrated electrothermal coupling simulation model was constructed to support the equivalence of physical parameters of complex interconnect structures, realize efficient calculation of electrothermal bidirectional coupling, and accurately describe the temperature change behavior of integrated chips under the Joule heating effect. In addition, based on the above model and algorithm research progress, the thermal simulation method was expanded to a larger scale, and a wafer-level thermal simulation simulator was independently developed. The simulator can provide larger-scale thermal simulation analysis for core-grain heterogeneous integrated chips, while supporting the design of heat sink fluid dynamics models. The simulation results are closer to the potential temperature hotspot prediction of actual application scenarios, which helps to optimize the thermal design simulation process. Compared with the finite element method, the number of simulator units is reduced by 2.78 times, the running time is reduced by 25.9 times, and the relative error is 0.38%. At present, the research team has carried out key technology cooperation on thermal simulation with well-known domestic enterprises, and the relevant models and algorithms are undergoing application verification.
