In October 2022, the US Bureau of Industry and Security (BIS) imposed a package of export restrictions on China, including controls on equipment and components for manufacturing 3D NAND with 128 layers or more, and restrictions on support provided by US persons.

Delta Electronics showcased its on-site solid oxide fuel cell (SOFC) power generation solution at Energy Taiwan 2026, alongside its first physical solid-state transformer (SST) product.

Micron Technology on October 15 opened Micron Advanced Assembly and Test Taiwan 2 (AATT2) in Taichung, its second advanced assembly and test facility in Taiwan. The plant expands the company's packaging and testing capacity for high-bandwidth memory (HBM) as AI demand grows.

Synopsys CEO Sassine Ghazi said that fully autonomous chip development has not yet crossed the final hurdle to become reality, although the company has advanced from AI-assisted engineering to models that coordinate more than 40 task agents. He made these comments during the CEO Summit at SEMICON West 2026, adding that AI-era chip development requires co-optimization across physics, materials, processes, architectures, software, and models.

Samsung Ventures and Applied Ventures, the venture capital arm of Applied Materials, have invested in US-based Flexcompute, backing simulation technology designed to predict semiconductor packaging deformation before manufacturing. The investment comes as increasingly complex AI chips create new challenges in managing thermal stress, warpage, and manufacturing yields.

Intel used the Open Compute Project (OCP) Global Summit in San Jose to argue that AI is moving away from giant models in centralized data centers.

GlobalFoundries (GF) has reached a multiyear manufacturing agreement with TSMC to expand silicon interposer capacity at its Malta fab in New York, supplying TSMC's Chip-on-Wafer-on-Substrate (CoWoS) advanced-packaging ecosystem. The agreement is expected to be worth US$2 billion over an initial five-year term.

Iridium Communications and Altair Semiconductor are joining forces to help IoT devices stay connected outside terrestrial coverage, a move that could affect industries from logistics to wearables worldwide. The partnership aims to give manufacturers a simpler path to global satellite-enabled connectivity, without adding separate satellite hardware to existing designs.

South Korea's LX Semicon is seeking buyers for more than 60 silicon carbide (SiC) power semiconductor patents, winding down a business it entered five years ago to reduce its reliance on display driver ICs (DDIs). The retreat comes as Taiwan's Novatek gains ground in the company's core display chip market, increasing pressure on LX Semicon to develop new revenue sources.

An explosion and fire at Intel's wafer fab in Kiryat Gat, southern Israel, on October 14, 2026, seriously injured three employees, one of whom later died of his injuries. Authorities deployed eight firefighting and rescue teams, including a hazardous-materials unit, to investigate the cause and assess the risk of a chemical leak involving nitrogen trifluoride (NF3).

Speaking to more than 2,000 Tesla owners and investors at the X Takeover event held at Tesla's Gigafactory in Austin, Texas, on October 11, Elon Musk made a candid admission: "To be clear, I don't know how to make chips." He immediately followed it with a declaration: "We'll figure it out."
