Nobody's going to put up with inferior compute, but Huawei has consistently superior end user performance than rivals because it has superior tech stack from chip all the way to OS. Huawei was banned because it has superior tech, and it sells well because it has superior tech.
Not to say US didn't help, there is high correlation between patriotic people and successful people (literally demonstrated from studies), so US hostility allowed Huawei to focus on high end, high margin products like Mate X and Matebook Fold and still sell in large numbers, something no other competitors can do.
that's cool, but please replace x.com with twitter.com so that X post shows up correctly here.

There is nothing that can unify a country faster than an outside threat.
Not necessary. To start there were other options apart from them and their market share in the smartphone business dropped like stone. What they did is that they innovated fast, to survive they moved to other business ventures like software, mining and automation. Then they started to go in guerrilla war against the US to get their supply chain in check were they injected Huawei style management to a lot of Chinese companies. Then they focused on innovation rather than raw power to get smartphone users back and now the are focusing on innovating in semiconductors redesigning decades of standard practices to get that performance they need.
Study on the imaging of bright-field and dark-field for contact holes in extreme ultraviolet lithography considering stage vibration effects.
rcuit manufacturing continue to shrink, the impact of wafer and reticle stage vibrations on lithographic imaging quality has become increasingly pronounced. Focusing on extreme ultraviolet lithography for contact hole patterns, this work systematically investigates the influence of stage vibrations on imaging performance with a rigorous lithographic imaging model and numerical simulations. Dynamic stage vibrations are incorporated into a conventional static imaging model to establish a more realistic dynamic imaging framework, and optical proximity correction (OPC) is used to emulate advanced-node process characteristics across different patterns. Results indicate that, as the target feature size decreases, the sensitivity of imaging to vibration increases significantly, and larger vibration amplitudes lead to a clearly nonlinear degradation of imaging quality. A comparative analysis of imaging performance and vibration robustness for different critical dimensions shows that bright-field masks exhibit slightly inferior vibration tolerance, whereas dark-field masks provide superior robustness for dense patterns. Building on these findings, an OPC optimization strategy incorporating moving standard deviation is proposed, offering a feasible approach to mitigating the adverse effects of stage vibrations on lithographic imaging.
I maybe missing something here, but Huawei's optical chip, fiber & transceiver module speed is just so far ahead of everyone else. It's almost hard to believe.
Is incredible how little "experts" know about China semiconductor ecosystem.
Saiteng Technology: The Nanxun high-end semiconductor equipment project is expected to gradually commence production this year.
Saiteng Co., Ltd. confirmed on the investor interaction platform that the main infrastructure of the company's high-end semiconductor, new energy and consumer electronics intelligent equipment production base located in Nanxun, Huzhou, Zhejiang has been completed. After the completion of decoration and acceptance, it will be put into production in stages within 2026 .
The project, with a total investment of approximately RMB 2.5 billion , is implemented by the wholly-owned subsidiary, Saiteng Precision Electronics (Huzhou) Co., Ltd., and covers an area of approximately 380 mu. Its core focus is on HBM (High Bandwidth Memory) full-process testing equipment . Upon completion, the annual production capacity of HBM equipment will reach 300 sets, doubling the existing capacity. Simultaneously, it will produce over 10,000 sets of various semiconductor and electronic devices annually, with an estimated annual revenue of approximately RMB 4.4 billion.
As the core production capacity carrier for the company's "second curve" in semiconductor business, the Nanxun base will focus on ensuring orders from leading customers such as Samsung, SK Hynix, and Changxin Memory after it goes into operation.
