Japan's three major power semiconductor makers — Rohm Semiconductor, Toshiba, and Mitsubishi Electric — have failed to complete integration talks on the original schedule, as leadership disputes and a surge in AI demand slow the effort to boost the competitiveness of Japanese manufacturers.

Onsemi has amended its agreement to buy Synaptics in an all-cash deal, a move that could reshape semiconductor competition and affect global technology supply chains. The revised cash transaction offers Synaptics shareholders value certainty, while regulators, customers, and investors now await decisions that may influence AI, sensing, and connected-compute markets worldwide.

The Science Park Review Committee under Taiwan's National Science and Technology Council (NSTC) approved 13 investment projects at its 35th meeting on the 1st, including Nanya Technology's plan to enter the Pingtung area of the Southern Taiwan Science Park and build advanced 3D semiconductor packaging and testing operations.

Hyperscale cloud service providers (CSPs) are expanding their custom ASIC partner networks, accelerating a shift toward multi-vendor technology integration. Industry insiders note that the era of a single design partner handling an ASIC project end-to-end is largely over, replaced by a co-design model where vendors compete for functional silicon footprint within single-chip architectures.

Advanced Micro Devices (AMD) has agreed to acquire World Labs in an all-stock transaction valued at approximately US$8.2 billion. Following the closing, World Labs will operate as a dedicated frontier research organization for large language models (LLMs) and spatial intelligence, with founder Fei-Fei Li joining AMD as executive vice president and chief scientist, reporting directly to Chair and CEO Lisa Su.

Machvision is expanding capacity earlier than planned to meet rising demand from semiconductors, substrates, and optical modules, while tight computer numerical control (CNC) and machining supply chains have emerged as its biggest operating challenge. The inspection equipment maker is reshaping its Hsinchu and Kunshan facilities and expects the new footprint to support NT$10 billion (US$313.03 million) in revenue starting in 2027.

Topco Scientific said its Japanese subsidiary, Shunkawa, officially opened its Fukuoka office on October 1, making it the company’s third base in Japan alongside its Tokyo headquarters and Kumamoto office. The move is designed to leverage Fukuoka’s location and industrial clustering to strengthen real-time technical support and new business development in Kyushu’s semiconductor hub.

Infineon Technologies officially inaugurated a new backend manufacturing site in Samut Prakan, south of Bangkok, on October 1, expanding the German chipmaker's production network in Southeast Asia starting with an initial investment of over EUR100 million (US$113.1 million).

Advanced Semiconductor Engineering (ASE) held its 11th Automation Industry-Academia Project Results Presentation on September 30, unveiling 12 technology projects developed with six Taiwanese universities as it works to advance smart outsourced semiconductor assembly and test (OSAT) and digital manufacturing. The projects were designed to support semiconductor factory efficiency, quality control, resilience, and climate adaptation.

Shinko Electric Industries announced on September 30 it has signed a purchase agreement to acquire the Mobara Fab from Japan Display (JDI) in Mobara City, Chiba Prefecture. The transaction is intended to establish a new core production hub dedicated to high-end semiconductor packaging, addressing surging global demand for AI accelerators and data center applications.

Huawei rotating chairman Eric Xu said the company's Ascend AI accelerators have surpassed Nvidia in both sales and market share in China, highlighting how US export controls on advanced AI chips are accelerating the shift of China's data center and AI industries toward domestic suppliers.
