AI infrastructure investment is accelerating the shift toward optical connectivity, as rising data-center traffic exposes the power and bandwidth limits of conventional electrical signals. Nvidia and ASE's SPIL are expanding the supply of optical engines for co-packaged optics (CPO), targeting a 15x capacity increase by mid-2027 and a 30x increase by the end of 2028 as CPO moves toward volume shipments.

Recent developments, including the Democratic Party's strong showing in the US midterm elections and calls for Nvidia CEO Jensen Huang to brief Congress on national security matters, have stirred uncertainty over the future direction of AI policy and the AI chip market in the US. Huang has also drawn global media attention after addressing an alleged extramarital affair in an open letter.

Samsung Electronics and SK Hynix face uncertainty over demand for high-bandwidth memory (HBM) as US lawmakers press for tighter controls on AI chip exports to China following allegations involving Nvidia CEO Jensen Huang.

Novatek Microelectronics, a leading Taiwanese display driver IC (DDI) design house, hosted its quarterly earnings conference last week. Novatek President and Vice Chairman Steve Wang stated that third-quarter 2026 revenue reached the upper end of its guidance, propelled by seasonal stock-up demand from smartphone clients that drove strong shipment growth in small- and medium-sized DDIs. Small- and medium-sized DDIs accounted for 37% of total revenue during the quarter, while system-on-chip (SoC) revenue share declined from 52% in the second quarter to 46%. The quarter-over-quarter compression in gross margin reflected this product-mix shift, as well as the timing lag between rising input costs and product price adjustments.

Phison Electronics CEO Pua Khein-Seng expects AI demand to surge again after the Lunar New Year, tightening NAND Flash supplies and intensifying competition for high-capacity triple-level cell (TLC) and quad-level cell (QLC) products. The company has already secured more than 70% of its targeted 2027 supply.

Zhu Yiming, chairman of ChangXin Memory Technologies (CXMT), reportedly participated in Chinese AI startup DeepSeek's second funding round, drawing attention to his semiconductor investment network. Neither DeepSeek nor the reported investors have confirmed the claims, leaving the investment entity, amount, and shareholding structure unclear.

US scrutiny surrounding Nvidia CEO Jensen Huang is expanding across national security, chip export enforcement, and shareholder disclosures, with US President Donald Trump saying the FBI is examining his relationship with an alleged Chinese agent as lawmakers seek answers and investors take the company to court.

Mitsui Chemicals plans to acquire semiconductor materials maker JSR in a transaction valued at JPY1.84 trillion (approx. US$11.6 billion), including assumed debt, as it seeks to strengthen its position in the global semiconductor materials market and accelerate a broader business portfolio transformation.

Google has expanded its eighth-generation TPU portfolio with the announcement of two specialized AI systems—the TPU 8tx for hardware-encrypted confidential compute and the TPU 8i Max for high-density context workloads. Joining the previously released TPU 8t training engine and TPU 8i reasoning engine, this update marks the first time Google has shipped four distinct TPU systems in a single year to serve its frontier research customers.

In a Cambridge laboratory, an automated testing machine sits at the end of a process that has traditionally demanded years of specialized engineering: designing a photonic chip, sending it for fabrication, and discovering whether light behaves inside the finished device as simulations predicted.

Polytetrafluoroethylene (PTFE), the material behind the Teflon brand, has become one of the most closely watched materials for advanced electronics, drawing attention at the Open Compute Project (OCP) Global Summit and the Taiwan Printed Circuit Association (TPCA) International Exhibition.
