first_img SemiAnalysis: ASML is currently developing hybrid bonding equipment

On October 15, the semiconductor research organization SemiAnalysis published an article stating that the lithography equipment manufacturer ASML has not officially announced related products, but patents, news reports, and the company's roadmap all indicate that it is developing hybrid bonding equipment. The author of the article judges that ASML may first launch more challenging chip-to-wafer hybrid bonding tools and view it as an extension of vertical integration.Patents show that the system operates on a track, with each chip placed in an independent carrier, sequentially completing inspection, cleaning, plasma activation, morphology inspection, leveling, coarse alignment, position adjustment, and fine alignment before entering the bonding station; the final placement is completed by the carrier and suction cup. The track's repeat accuracy is about 10 microns, far from the approximately 50 nanometers required for bonding. ASML submitted 27 bonding patent families from December 2022 to November 2024, most of which are aimed at chip-to-wafer. The Elec reported in March that ASML has begun hybrid bonding machine architecture design with Prodrive Technologies and VDL ETG.The article states that wafer-to-wafer hybrid bonding has been used for image sensors and 3D NAND; chip-to-wafer is currently only used for mass production of logic chips, including AMD's hybrid bonding V-Cache shipped since 2022 and TSMC's SoIC. The current spacing of SoIC is about 6 microns, with a target of reaching approximately 4.5 microns by 2029. Besi is currently the only supplier with chip-to-wafer mass production tools, with related logic business mainly concentrated in TSMC and Intel.

SemiAnalysis: ByteDance accounts for nearly one-fifth of China's data center capacity

The semiconductor research organization SemiAnalysis released a survey on Chinese data centers, tracking over 1,000 facilities from more than 60 operators. The report estimates that by the end of 2026, China's data center capacity will exceed 24GW, second only to the United States' 56GW. ByteDance accounts for nearly one-fifth of this, making it the largest data center tenant in the country.ByteDance has leased over 4GW of data center capacity, with suppliers including Qinhuai Data, China United Network Communications, and Century Internet. The report states that by early 2026, ByteDance will still contribute about 90% of Qinhuai Data's revenue. ByteDance has also begun to accelerate its self-built data centers, constructing large facilities in Shanxi, Anhui, and Inner Mongolia to reduce reliance on external suppliers.The report also mentions that while Chinese data centers have long been considered to have a high vacancy rate, AI server rooms are still in short supply. This is due to many old server rooms lacking sufficient power supply and cooling capabilities, making it difficult to directly deploy high-power AI servers, while newly built large AI data centers are quickly being rented out. For example, a 100MW data center, excluding IT equipment such as servers, has a construction cost of about $300 million in China and about $1.5 billion in the United States, with Chinese facilities of the same scale typically delivered in about 12 months. Compared to the power supply and approval issues faced by the United States, the more prominent bottleneck for expanding AI data centers in China is the supply of advanced chips.

first_img Umia raised $6.11 million through the auction of UMIA tokens, with a fully diluted valuation (FDV) reaching $18 million

The platform Umia, which helps cryptocurrency projects issue and govern tokens, completed a $6.11 million financing by auctioning its own UMIA tokens. Francesco Mosterts, co-founder and CEO of Umia, told The Block that the seven-day auction had a fully diluted valuation of $18 million, selling a total of 17.3 million tokens, which accounted for 34.6% of the total supply. All tokens sold in the auction were unlocked at issuance, with no lock-up period. According to CoinGecko data, the current trading price of UMIA is approximately $0.68, corresponding to a fully diluted valuation of about $34 million.About 45% of the funds came from institutional investors, with ten funds participating, including Galaxy Ventures, Digital Currency Group, Draper Associates, RenGen, Alpha EV, Maven 11, and Eon Capital, along with nearly 700 individual bidders. Umia stated that these funds had the same terms as other bidders, did not receive discounts, and no investors were granted board seats, observer roles, or advisory positions. The auction took place from August 26 to September 2 on Base, using Umia's version of Uniswap's continuous liquidation auction, with a minimum target of $2 million and a maximum token price of $0.36.Umia places the intellectual property, operational team, and treasury of each project under the same legal structure associated with the tokens, rather than being dispersed among companies, foundations, and DAOs.
