Backed by US$15 billion in Japanese government funding, Rapidus announced an alliance with 17 semiconductor design-related companies, including US-based Synopsys and India's Infosys, on October 5. The partnership aims to expand its potential customer base by helping companies develop custom chips.

SK Hynix's proposed KRW400 trillion (approx. US$299 billion) semiconductor expansion in southwestern South Korea faces a major obstacle as the company races to increase memory production capacity: the planned manufacturing site includes military facilities used by US forces, complicating construction timelines as competition intensifies with Micron Technology and Chinese chipmakers.

Samsung Electronics and SK Hynix have accepted a 10% increase in ASML's replacement-part prices for lithography systems in South Korea, with the higher rates taking effect for deliveries starting in January 2027, The Elec reported on October 11, citing industry sources.

LG Display has unveiled a new organic light-emitting diode (OLED) manufacturing technology designed to improve production efficiency and display performance, and reduce manufacturing costs as it prepares to expand into the information technology display market.

A former iPhone display factory in Mobara, Japan, is set for a new role in the semiconductor supply chain, with Shinko Electric Industries planning to convert the site into a production base for semiconductor package substrates used in artificial intelligence (AI) applications.

Kawasaki Heavy Industries is betting on physical AI as part of a multibillion-dollar growth plan to modernize factories, address labor shortages, and expand robotics across shipbuilding, aerospace, and healthcare. The move signals how one of Japan's major industrial groups plans to compete in a global market where automation is increasingly central to productivity, resilience, and long-term growth.

This week's (October 5 to October 11, 2026) coverage highlights intensifying efforts to build resilient semiconductor and AI hardware supply chains. Elon Musk's Terafab project faces manufacturing, packaging, printed circuit board (PCB) yield, partnership, and governance questions, while Intel remains involved and TSMC's role may be limited. Samsung reportedly advances HBM4E high-bandwidth memory validation and glass interposer testing. Vicor expands patent litigation over AI server power systems. Taiwan restricts China-made fiberglass sleeves, and China's new five-year plan prioritizes advanced PCBs, materials, equipment, and domestic investment.

The hardware boundary separating cloud-scale AI from local inference is becoming increasingly porous as PC vendors expand memory capacity and software platforms make larger open-weight models easier to run directly on devices.

Samsung Electro-Mechanics (Semco) has reportedly completed initial reliability testing of its 100mm glass substrates and moved to package-level verification using customer chips, marking progress toward commercializing next-generation packaging technology as AI accelerators grow larger and more complex. The development comes as the company expands its existing semiconductor substrate business while facing uncertainty over the commercialization timeline for glass substrates.

SK Hynix's dynamic random-access memory (DRAM) and Universal Flash Storage (UFS) products have reached orbit aboard a South Korean satellite that successfully established communication with the ground following the country's fifth Nuri rocket launch. The mission opens the way for in-orbit reliability testing as the memory maker explores potential opportunities in the space electronics market. No in-orbit test results for SK Hynix's memory products have been announced.

China's state-backed Guowang (GW) low-Earth-orbit (LEO) satellite network has completed its first communications test during the country's 16th Arctic expedition, enabling a live video call linking vessels in the Arctic with Qinling Station in Antarctica with reported latency under one second.

Samsung Electronics' next-generation 12-layer HBM4E product, a type of high-bandwidth memory (HBM), has reportedly cleared customer quality validation from Nvidia and major hyperscale data center operators. If confirmed, the result would strengthen Samsung's bid to supply memory for next-gen AI accelerators, though order timing and mass production plans remain unclear.

LG Group is preparing to test five commercial components developed by LG Electronics, LG Innotek, and LG Energy Solution (LGES), including cameras and batteries, aboard a CubeSat carried as a secondary payload on South Korea's fifth Nuri rocket launch. The mission aims to assess whether commercially available components can operate reliably in space.
