Like I stated before you guys are way too hard on Lenovo. If they were complete sellouts would they do something like this?
Chinese-owned German wafer factory to expand chip production by $200 million
Nexperia, a Dutch chipmaker under Wingtech Technology, will invest $200 million to develop and manufacture semiconductors at its Hamburg plant in Germany.
Nexperia, one of the world's largest makers of basic semiconductors such as diodes and transistors, said in a statement that it intends to build two "wide bandgap" chips for electrical infrastructure, silicon carbide (SiC) and gallium nitride (GaN), at the plant over the next two years. These chips are favored over regular silicon chips because of their high efficiency, speed, light weight and ability to operate under high temperature and high voltage conditions.
“Electric mobility, green energy and digitalization are unthinkable without our products,” Nexperia Chief Financial Officer Stefan Tilger said in a statement announcing the investment. “They are fundamental elements that make new technologies possible.”
Nexperia produces 100 billion of these chips a year, nearly a quarter of the world's supply, with assembly and packaging taking place in China, Malaysia and the Philippines.
Nexperia competes with Texas Instruments, Infineon Technologies and NXP Semiconductors in the automotive market, with about 10% of its sales going to Chinese customers.
“We have a very ambitious growth curve and it’s a steep growth curve,” said Hannes van Raemdonck, Nexperia’s head of evangelism, adding that the company is investing to benefit from trends such as electrification and the increasing number of semiconductors used in cars. “Everything needs more chips to power the devices, (and) power semiconductors are our core business,” he said.
Meanwhile, the EU is eyeing simpler "legacy" chips made in China that are used in cars, power systems, smartphones and industrial applications. All of Nexperia's manufacturing and intellectual property is in Europe.
In 2018, Wingtech Technology acquired Nexperia for US$3.6 billion.
Hannes van Raemdonck said Nexperia competes with Chinese companies and he appreciated European policies aimed at ensuring its companies remain competitive. However, he was sceptical about concerns that Chinese companies would invest in excess capacity, “assuming that most of China’s capacity expansion is to meet domestic demand”.

Iodonium Functionalized Polystyrene as Non-Chemically Amplified Resists for Electron Beam and Extreme Ultraviolet Lithography.
Abstract
A novel non-chemically amplified resist (n-CAR) based on biphenyl iodonium perfluoro-1-butanesulfonate modified polystyrene with naphthylamide scaffold (PSNA0.4) was synthesized and characterized. Through extensive exploration using dose-dependent resist thickness analysis, acetonitrile was identified as the optimal developer. Employing electron beam lithography (EBL), the n-CAR of PSNA0.4 demonstrated its high-resolution patterning capability by resolving a dense line pattern of 18 nm L/S at an exposure dose of 1300 μC/cm2, achieving a high contrast of 7.1. Further studies using extreme ultraviolet lithography (EUVL) demonstrated that PSNA0.4 resist can achieve 22 nm L/S patterns at a dose of 90.8 mJ/cm2, underscoring its high sensitivity for n-CARs. Detailed studies to gain insight into underlying patterning mechanisms using X-ray photoelectron spectroscopy (XPS) suggest that the cleavage of polar iodonium into nonpolar polystyrene (PS) based iodobenzene species enable the solubility switch, resulting in negative lithographic patterns. These findings highlight the innovative potential of the PSNA0.4 resist in advancing the capabilities of n-CAR technologies, particularly in the realms of EBL and EUVL, for high-resolution lithographic applications.
you have very bad habit to ignore previous posts on this topic. you don't read previous massages and continue to post such nonsense articles all the time .. @tphuang has clarify many times before..
20% base on what? what calculations? oh yeah unknown sources.
Ok, my "sources" tell me that SMIC has been replacing US made tools with domestic tools and non US tools at a pretty fast pace, that why that huge jump in japanese tools and why NAURA, AMEC, PIOTECH and others has been fast tracking the releases of their high end tools. SMIC and Huawei has been working improving their manufacturing process since 2020, so that article is full of crap.
That article is actually slightly different but it basically quotes a random source. And some of its statements seem just quite ignorant. I will say that I don’t expect ascend 910b to have good yields but it has been in production for over a year for sure and a new gen gpu is coming out. So this is why we need to be very careful posting random takes, because a lot of them are just low quality.

The tipster states that the new Huawei Taishan cores will outperform the Kirin 9000S’ Cortex-A510 cores. So while they will be more efficient, they will bring a significant performance bump.
The upcoming Taishan V130 architecture will aim to compete with Apple’s M3 chip and will be based on the 5nm manufacturing node.
