South Korea's JNTC has joined Nvidia's purchasing supplier list and is supplying paid samples of through-glass via (TGV) substrates, including 2mm-thick glass cores, The Elec reported on November 6.

National Silicon Industry Group (NSIG) expects to complete its expansion to 1.2 million 300mm silicon wafers per month by the end of 2026, positioning the Chinese semiconductor materials supplier to benefit from recovering wafer prices and growing demand for silicon-on-insulator (SOI) substrates used in silicon photonics (SiPh).

Optoelectronic chip testing equipment maker EnliTech reported self-assessed consolidated revenue of approximately NT$51.504 million (US$1.57 million) in October 2026, up 71.33% year over year and a record high for the month. Revenue exceeded NT$50 million for the second consecutive month, while cumulative revenue for the first 10 months of 2026 reached approximately NT$372 million, up 44.63% from the same period in 2025.

PCB maker Eiso Enterprise posted strong growth in the third quarter of 2026 as AI server backup battery unit (BBU) products began shipping, driving demand for high-end printed circuit boards (PCBs) and lifting the company’s quarterly gross margin to 27.37%.

AI data centers are accelerating demand for high-speed optical communications, extending competition in the optical transceiver market beyond chips and module manufacturing to critical upstream materials. Indium phosphide (InP), a key substrate for high-speed optical lasers and optoelectronic devices, is increasingly sought after as 800G and 1.6T transceivers gain traction. With capacity expansion requiring time and product qualification presenting technical hurdles, securing InP wafer supplies has become a strategic priority for optical communications companies.

Murata Manufacturing and Samsung Electro-Mechanics (Semco) have reportedly secured silicon capacitor production capacity from Winbond Electronics to meet demand from their end customers, as the Taiwanese memory maker expands into components used in AI advanced packaging.

Marvell Technology and optical communications laser maker Lumentum announced on November 2 that they had signed a definitive agreement for Marvell to acquire Lumentum in an all-stock transaction. Compound semiconductor maker GCS welcomed the deal, saying it will give Marvell's optoelectronics business a more complete product portfolio.

Panasonic Industrial Devices Materials Taiwan's Hukou plant experienced an explosion and fire early on November 4, injuring five employees and leaving two others unaccounted for. The fire continued to spread through the five-story, steel-framed, metal-clad facility, while the cause and extent of the damage remained under investigation.

As AI computing clusters continue to expand, data centers are demanding higher transmission speeds and greater bandwidth. To overcome the manufacturing bottlenecks of traditional high-density interconnect (HDI) technology, modified semi-additive processes (mSAP) are rapidly emerging as the new market mainstream for optical communications modules and high-end server PCBs.

AI data centers are increasing demand for high-speed optical communications, making optoelectronics supply chains increasingly strategic. Marvell's announced acquisition of Lumentum highlights chipmakers' growing integration of optical technologies. Huawei has pursued its own supply-chain strategy through sustained equity investments by Hubble Technology.

Samsung Electro-Mechanics (Semco) has disclosed more than KRW5 trillion in long-term supply agreements (LTAs) this year after signing another AI server capacitor contract. The company expects such agreements to account for more than half of its multilayer ceramic capacitor (MLCC) revenue in 2027.

Panasonic Industry, the electronic components subsidiary of Panasonic Group, plans to invest approximately JPY92 billion (approx. US$582.8 million) in its AI-related businesses to meet surging demand driven by generative AI. The investment will accelerate production capacity expansion and R&D for advanced circuit board materials, specialized capacitors, and next-generation semiconductor materials.

The printed circuit board (PCB) shortage that Indian electronics makers expect to worsen in the coming months is part of a global squeeze. AI servers are absorbing high-end laminate, glass fiber cloth, and Ajinomoto Build-up Film (ABF) capacity; the war in West Asia has cut off a key resin; and equipment for new capacity can take up to 30 months to deliver. Supply chain estimates cited in Taiwan suggest the tightest materials will ease only gradually, from the second half of 2027 through 2028.

Competition in the AI application-specific integrated circuit (ASIC) market will extend beyond 2028, industry sources said, with MediaTek, Broadcom, and Marvell competing not only for design wins, but also for secure access to wafers, advanced packaging, substrates, and high-bandwidth memory (HBM). The effectiveness of their supply-chain partnerships will determine how much revenue each company can ultimately generate.

SK Hynix is increasing orders for small outline compression attached memory module 2 (SOCAMM2) printed circuit boards (PCBs) as production ramps up for Nvidia's Vera Rubin AI platform, while shortages of copper-clad laminate (CCL) and other materials are pushing up substrate prices, South Korea's Dealsite reported on October 30.

Samsung Electro-Mechanics (Semco) has begun mass production of a miniature, ultra-high-capacitance multilayer ceramic capacitor (MLCC) for advanced driver assistance systems (ADAS), as increasingly powerful automotive processors drive demand for smaller components capable of maintaining stable power supplies.

Murata Manufacturing announced plans to invest around JPY1 trillion (US$6.3 billion) in expanding multilayer ceramic capacitor (MLCC) capacity by 2030. Booming demand from data centers and AI applications has pushed up orders for MLCC makers. MLCCs are a crucial component in managing power demand.
