According to public information, Samsung Electronics recently filed a new patent for High Bandwidth Memory (HBM) packaging, aiming to address the reliability challenges faced by high-stack products such as HBM4E and HBM5.

To proactively address the surging global demand for AI memory, SK Hynix has formulated a medium- to long-term investment strategy totaling 110 trillion won (approximately $71.3 billion).

According to South Korean media reports, Samsung Electronics has detailed its group-wide domestic investment plan valued at 2,655 trillion Korean won. The core of this plan is to expand production bases across the country, with a focus on developing artificial intelligence (AI) Semiconductors, robotics, batteries, and IT components and materials. It is reported that Samsung is investing 2,030 trillion won in nurturing Semiconductor clusters, including the Pyeongtaek complex and the Yongin National Industrial Complex, and plans to invest 625 trillion won in the Honam, Chungcheong, and Yeongnam regions, with a focus on AI Semiconductors, robotics, batteries, and IT components and materials.

Applied Materials has unveiled its product line of three-dimensional (3D) chip manufacturing equipment for AI Semiconductors. The series primarily focuses on planarization, deposition, and metrology and inspection required for advanced packaging processes such as high-bandwidth memory (HBM), chiplets, and hybrid bonding. Specifically, the offerings include advanced chemical mechanical polishing (CMP), electrochemical deposition (ECD), and plasma-enhanced chemical vapor deposition (PECVD) equipment for packaging applications, along with newly added electron-beam-based process control tools and enhanced epitaxial equipment for DRAM processes.

According to a report by South Korean media outlet inews24, SK Hynix's U.S. listing process has entered its final sprint. Meanwhile, Kioxia has released a timeline for issuing American Depositary Receipts (ADRs) in the U.S. and plans to implement a stock split to lower the entry barrier for retail investors. The intensive moves by these two industry titans signal that the AI memory supercycle is driving a profound restructuring of global capital markets.

According to foreign media reports, Intel has announced that the upgraded version of its 18A process node, 18A‑P, has officially entered the risk production stage. The 18A‑P process is based on the 18A node that entered mass production in the fourth quarter of last year, and is optimized for manufacturing data‑center CPUs as well as Semiconductors for artificial intelligence and high‑performance computing (HPC). Compared with 18A, the 18A‑P offers up to a 9% performance improvement at the same power consumption, and can reduce power consumption by as much as 18% at the same performance level. In addition, Intel plans to use 18A‑P to produce its "Diamond Rapids" CPU chips, which are expected to be released next year.

According to Korean media reports, Tae-joon Song, Vice President of Samsung Electronics' Foundry Business Division, stated today that the division will expand its Multi-Project Wafer (MPW) process to 2 nanometers next year. The 2nm process is currently the most advanced commercially available process. Due to its extremely high manufacturing complexity, it is currently only used in specific ultra-high-performance Semiconductor fields such as AI and HPC. This move is expected to accelerate the development of ultra-high-performance AI Semiconductors by domestic fabless companies in South Korea.

According to South Korean media citing SK hynix and fire authorities on the 12th, a fire broke out around 9:55 a.m. (local time) on the second floor of Building M15X, located within SK Hynix's Cheongju plant in Heungdeok District, Cheongju, North Chungcheong Province. After the fire broke out, employees from M15 and M15X were immediately evacuated outdoors. Reports indicate that the company's firefighting team extinguished the fire in its early stages. Cheongju issued a disaster alert, advising nearby residents to avoid the area and vehicles to take detours due to concerns over potential fluoride leaks. According to the latest news, the fire department stated that the investigation found no gas leakage. SK hynix stated that initial control has been completed, and the company is investigating the specific circumstances, adding that production equipment is operating normally. A fire also broke out at SK hynix's Cheongju Site 4 on the 1st of this month.

TSMC announced its revenue report for May 2026. Consolidated revenue for May 2026 was approximately NT$416.975 billion, up 1.5% month-on-month and 30.1% year-on-year. Cumulative revenue from January to May reached approximately NT$19,618.004 billion, with an increase of 30.0% compared to the same period last year. TSMC's revenue remained high in May, indicating that the momentum of AI supply chain shipments has not significantly cooled. In particular, demand for NVIDIA's Blackwell and Rubin platforms, AMD's high-end AI accelerators, custom ASIC chips from US-based cloud service providers (CSPs), and component stocking for new Apple products are all progressing simultaneously, continuing to drive capacity utilization rates for 3nm, 5nm, and advanced packaging technologies.

According to Korean media reports, Samsung Electronics is pushing ahead with the construction of an advanced Semiconductor packaging (back-end process) plant in Gwangju, marking the company's first Semiconductor production base in the Honam region (its current facilities are mainly concentrated in the Chungcheong region). This will be Samsung Electronics' first new packaging facility in 35 years since the establishment of its Onyang plant. The project is also expected to include front-end production lines for DRAM and NAND flash memory. The investment plan is reportedly scheduled for discussion on the 29th during a meeting chaired by President Lee Jae-myung, which will include heads of major corporate groups including Samsung.

The core objective of the plan is to increase monthly DRAM capacity from the current approximately 550,000 wafers (which includes around 200,000 wafers produced at the Wuxi plant in China) to roughly one million wafers by 2030. This expansion will be heavily concentrated in the Yongin Semiconductor Cluster.

Semiconductors were undoubtedly the absolute powerhouse behind this impressive performance. In May, South Korea's Semiconductor exports skyrocketed by 169.4% year-on-year, reaching $37.16 billion, shattering the previous all-time high of $32.8 billion set in March.

Samsung Electronics announced that it has begun shipping the industry’s first 12-layer HBM4E samples to major global customers, further strengthening its leadership in the next-generation HBM market.

Solidigm announced new co-chief executive officers, Xin Guo and Richard Chin.

According to the latest reports from South Korean media, labor negotiations between Samsung Electronics and the union broke down again today (May 20). The Samsung Electronics union has officially announced that it will proceed with the general strike as planned tomorrow (May 21). Management has explicitly rejected the strike proposal. Calls from Samsung shareholders for an emergency arbitration process are growing increasingly urgent.
