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.

According to Gate market data, the Philadelphia Semiconductor Index is expected to evaporate more than 2 trillion USD in market value within seven trading days.

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.

French semiconductor company Sequans Communications has sold its last 314 bitcoins, completing its exit from the bitcoin reserve strategy, having previously held over 3,200 BTC. Sequans stated that this exit was conducted after the redemption of convertible bonds completed in May, allowing it to refocus on its core cellular IoT and software-defined radio business.Sequans CEO Georges Karam stated that the company used the proceeds from the bitcoin sales to pay off convertible bonds and strengthen its balance sheet. Currently, Sequans holds no cryptocurrency and has no outstanding debts other than government-funded R&D obligations. Sequans launched its bitcoin reserve strategy in June 2025, announcing a $384 million equity security and convertible secured bond issuance, with Karam at the time calling bitcoin a primary asset and an attractive long-term investment.The company began to reduce its holdings less than six months later, selling 970 BTC in November to redeem half of the convertible bonds. By May 2026, Sequans indicated that it would no longer pursue the reserve strategy and would gradually liquidate the remaining bitcoins. During the 2026 crypto bear market, an increasing number of digital asset reserve companies abandoned or scaled back their accumulation strategies. VanEck's head of digital asset research, Matthew Sigel, noted at the end of July that at least nine companies had completely liquidated or abandoned their bitcoin and cryptocurrency reserve strategies in 2026.
