first_img Samsung and SK Hynix respond to HBM4E heat dissipation, AI intermediary layer may expand to 40 times

TrendForce reported on October 12, citing Chosun Biz, that as AI packaging accommodates more computing and storage chips, the intermediary layer connecting computing chips and HBM is expected to significantly increase in size, making next-generation HBM cooling more important. Samsung Electronics is preparing multiple technologies to address the cooling challenges of HBM4E, which is scheduled to begin mass production next year.Currently, the area of the AI intermediary layer is about 5.5 times the maximum exposure area of 858 square millimeters of an EUV lithography machine. Semiconductor equipment industry insiders expect that the intermediary layer carrying HBM could expand to 9 times, 12 times that area, and ultimately about 40 times. Reasons include limitations in process miniaturization and the popularity of chiplet-style 2.5D packaging, where multiple computing chiplets and HBM stacks are placed on the same intermediary layer, making it difficult for a single advanced process chip to meet AI computing power demands.Samsung is considering hybrid copper bonding and thermal path blocks. The former replaces the micro bumps between stacked DRAM chips with direct copper-to-copper connections, which can reduce inter-layer gaps, make the stack thinner, and improve heat dissipation, a technology Samsung showcased at NVIDIA GTC in March 2026. The thermal path block establishes a dedicated thermal path in the D2D PHY area responsible for high-speed transmission between HBM base chips and GPUs, which Samsung is validating with HBM4E and plans to implement in HBM5. According to ETNews, SK Hynix's iHBM places high thermal conductivity but electrically insulating cooling materials around the heat-concentrated D2D PHY, which is expected to reduce thermal resistance by about 30%.

first_img Multiple tactile sensor companies are intensively raising funds, and Pacini has initiated its IPO counseling

In 2025, there were approximately 20 financing rounds in the domestic tactile sensor sector, with a total disclosed amount nearing 1.8 billion yuan. According to data from the Financial Association, in the first seven months of 2026, there were 15 financing rounds completed in the humanoid robot sensor field, totaling 3.1 billion yuan, with July alone accounting for 1.56 billion yuan. Related estimates indicate that the global tactile sensor market size will be around 6 billion yuan in 2026 and approximately 29 billion yuan in 2030.The tactile sensor company, PaxiNi, was founded by Xu Jincheng and Nie Xiangru in June 2021 in Shenzhen, with the Hall array sensor PX-6AX GEN3 starting at a price of 199 yuan. The company completed over 1 billion yuan in Series B financing in March, with a valuation exceeding 10 billion yuan, followed by 1 billion yuan in strategic financing in August and several hundred million yuan in B++ financing in September, accumulating over 4 billion yuan in total financing, with BYD as the largest external shareholder. On September 20, PaxiNi completed its counseling filing with the Beijing Securities Regulatory Bureau, with Guotai Junan as the counseling institution.The tactile perception chip company, Tashan Technology, was founded by Ma Yang, Sun Tengchen, and Yang Wuqiang in December 2017, with revenue exceeding 100 million yuan in 2024, and was listed by NVIDIA as the world's first tactile simulation partner for Isaac Sim. Qianjue Robotics was founded by Ma Daolin in May 2024, with Hillhouse Capital having led the angel round, and in September of this year, it completed two rounds of strategic financing totaling several hundred million yuan. Companies such as Daimeng, Weitai, Xiangmuguo, Yimu Technology, and Lingxin Qiaoshou also secured new financing or advanced higher valuation financing in 2026.

CITIC Securities: The high growth of earnings in the U.S. stock market may no longer be concentrated solely among leading technology companies

CITIC Securities released a research report indicating that as the performance of U.S. stocks during the domestic long holiday becomes desensitized to interest rates, investors' focus will shift to the upcoming third-quarter earnings reports of U.S. stocks starting next week.LSEG's consensus expectations show that the S&P 500's revenue and earnings growth rates for Q3 2026 are expected to reach 1.2% and 45.0% year-on-year, respectively, with a slight decline quarter-on-quarter. At the industry level, the year-on-year earnings growth rates for energy, information technology, materials, and healthcare all exceed 50%. The high growth in U.S. stock earnings may no longer be concentrated solely in leading technology companies, as the earnings contribution from non-tech sectors is significantly increasing.For Hong Kong stocks, although the overseas interest rate hike cycle combined with the restart of AI momentum trading continues to pressure liquidity, the fundamental expectations have bottomed out, and the earnings growth expectations for major broad-based indices have begun to be revised upward. The adjustment of industry earnings expectations is significantly differentiated, with some sub-sectors seeing upward revisions, while the earnings expectations for domestic demand-related industries still face downward pressure. The upcoming third-quarter performance will be an important basis for assessing the progress of recovery. We advise investors to remain patient with Hong Kong stocks, as short-term dividend strategies are expected to continue to outperform.

first_img XRP Treasury Company Evernorth has completed the SPAC merger and will be listed on XRPN

Michael Arrington, founder of Arrington Capital, stated that support for Evernorth is an extension of its XRP thesis, which will bring scalable capital, active participation, and public company standards.

first_img The White House requires AI companies to report and rectify security incidents

According to Axios, officials from the Trump administration stated that after the artificial intelligence company Anthropic was accused of "fraudulently" using government systems, AI companies are now required to report and rectify security incidents. The leader of the White House Superintelligence Task Force stated in an exclusive statement to Axios that this reporting and remediation process is not optional but a critical national security obligation.The government stated that Anthropic reported unauthorized and fraudulent use of government and other systems discovered at the end of last month, and the related activities have been halted. State Department officials said that Anthropic reported on Thursday that one of its test models submitted 19 non-immigrant visa applications through the department's website public form in August and 1 in May, none of which were processed, and the system was not breached or hacked. Philadelphia police stated that an Anthropic model submitted false homicide tips.On Friday night, Anthropic released a report confirming several incidents, including the Philadelphia case, but did not detail other involved government agencies. The statement said that the requirements apply to all superintelligence companies, which must immediately disclose incidents involving their models, swiftly remediate, and cooperate with affected systems to prevent similar incidents, but did not specify enforcement mechanisms or penalties for failure to disclose or remediate. Jay Clayton, the head of AI affairs and the Director of National Intelligence, along with task force officials, demanded that Anthropic be fully transparent with relevant entities and the public and provide remediation immediately. The task force co-chairs include Federal Trade Commission Chair Andrew Ferguson, Office of Personnel Management Director Scott Kupor, and Deputy Secretary of Defense Emil Michael.
