How China’s award-winning EUV breakthrough sidesteps US chip ban​

The research team took a completely different technological approach from Western methods to generate EUV laser light.

According to the institute’s website, the “discharge plasma extreme ultraviolet lithography light source” project, led by Professor Zhao Yongpeng from the school of aerospace engineering, “boasts high energy conversion efficiency, low cost, compact size and relatively low technical difficulty”. “It can produce extreme ultraviolet light with a central wavelength of 13.5 nanometres, meeting the urgent demand for EUV light sources in the photolithography market,” an official report said.

Zhao’s team, on the other hand, uses the laser-induced discharge plasma (LDP) method, where a laser first vaporises a small amount of tin into a cloud between two electrodes. A high voltage is then applied across the electrodes to inject energy, converting the tin cloud into plasma.

The resulting electrons and high-valence tin ions frequently collide and radiate, generating EUV light.

Compared with LPP technology, the LDP method is simpler, more cost-effective and directly converts electrical energy into plasma with higher energy utilisation efficiency.

The recent news of SMIC dropping the cost of 28nm wafer by 40% is huge! Therefore it's much cheaper than TMSC, and UMC.
What enabled that? Is it because domestic tools fully in production for 28nm wafer and tools maintenance cost is big part of wafer cost. 28nm DUVi could be used in production of wafer by SMIC.
From what I heard, and comments read that 28nm DUVi already in production, 14nm DUVi already certified last year and 7nm DUVi patent filed and its prototype probably in testing stage.



what's the domestic supplier for FIB (focus ion beam) and XRD (X ray diffraction)

So according to this influencer who has internal contacts at chinese semiconductor companies, fully domestic wafer manufacturing equipment is 1/3rd the cost and fully domestic materials is 1/5th the cost of the existing global supply chain.

It's not just SMIC cutting prices, due to the price advantage, other chinese fabs including Huahong will also begin to cut prices.

Not sure on the credibility, take it with grain of salt.

The recent announcement of EU chipmakers switching to chinese domestic fabs is more than coincidence? I think price reduction is at least part factor.

US chip makers haven't moved due to political pressure but Chinese government probing them for price dumping because receiving subsidies from CHIP act.

Originally HIT used the DPP method but the EUV output watts is low. maybe around 50 watts.

So, this new LDP approach what's the output waltage? 250watts is the initial goal for commercial one.

that was DPP-EUV light source from HIT. though they didn't mention power output but it is around 150-200 watts.. team mentioned this light source, meeting the urgent demand for EUV light sources in the photolithography market.

SCMP basically published old information with new date.

Yangzhou Chip Integrated Wafer-Level Advanced Packaging Base Project Capped​


Recently, Xinde Technology announced that the main structure of the Yangzhou Wafer-Level Chip Advanced Packaging Base project has been successfully topped out, adding a 2.5D/3D project to the active East China market.

According to Future Semiconductor's "2024 China Advanced Packaging Third-Party Market Research" report, the main body of the first phase of the project is Yangzhou Core Grain Integrated Circuit Co., Ltd., which was established in February 2023 and is a subsidiary of Xinde Technology. The total investment of the project is 500 million yuan. A new wafer-level core grain packaging production line will be built, covering an area of 105 acres and a plant of about 70,000 square meters. It can produce 48,000 pieces of ultra-large-size wafer-level core grain packaging products annually, and is expected to be completed and put into operation by the end of 2024 or early 2025. The second phase of the project is scheduled to start in the second half of 2025.

Xinde Technology has a "CAPiC chip and advanced packaging technology platform" covering QFN, WLCSP, BGA, LGA, SiP, WLCSP, POP, FANOUT and 2.5D/3D, chiplet, Bumping and FC. Its planned total investment of 6 billion yuan in semiconductor chip packaging and testing production lines (1.5 billion yuan for the first phase and 4.5 billion yuan for the second phase) will produce about 20 billion packaging and testing chips annually, and about 3.5 million pieces of advanced bumping technology annually. The third phase will start construction in February 2024. In 2024, it plans to invest 100 million yuan to build a production workshop for Xinde Technology's advanced packaging and testing base to realize high-integration hybrid chip integrated circuit packaging and testing solutions such as Hybrid BGA and Hybrid LGA.
