Research on optoelectronic integration — referring to the application of optical communication technology to computing — is gaining momentum. Its semiconductor packaging component officially got underway in April 2026 in Chitose City, Hokkaido, Japan, where Rapidus's semiconductor factory is located. The project is led by the Leading-edge Semiconductor Technology Center (LSTC), with participation from Rapidus and other organizations, and has established a development base at the Chitose Institute of Science and Technology. By using light to connect individual chips within chiplets, the technology aims to significantly reduce the power consumption of AI chips.

Lam Research delivered a strong start to 2026, with first-quarter 2026 results exceeding expectations and reinforcing confidence in a semiconductor upcycle increasingly shaped by artificial intelligence demand. Revenue reached US$5.84 billion, up 24% year over year, while margins and earnings also came in above guidance.

Texas Instruments (TI) reported first-quarter 2026 revenue of US$4.83 billion, up 19% year on year, with net income rising 31% to US$1.55 billion and earnings per share of US$1.68. Operating profit increased 37% to US$1.81 billion.

Texas Instruments reported that improving demand in industrial and data center markets is driving sustained sequential growth, while management maintained a cautious stance on macroeconomic uncertainty and the durability of the current cycle.

Analysts say Lam Research is entering a stronger-than-expected growth phase, with rising demand from DRAM and NAND customers emerging as key drivers of revenue expansion alongside sustained AI-related investments. While overall semiconductor equipment demand remains cyclical, analysts note that memory-related capex recovery, combined with AI processor tool demand, is helping extend Lam Research's growth momentum into the next fiscal period.

Google Cloud Next 2026 kicked off on April 22 in Las Vegas, with Google Cloud CEO Thomas Kurian declaring that the experimental phase of artificial intelligence is over. Nearly 75% of Google Cloud customers are already using AI in production environments, he said, adding that the key challenge now is scaling AI deployment across entire enterprises.

At its North America Technology Symposium, TSMC showcased a range of innovations in advanced process technologies. Following the introduction of its A14 process in 2025, the company unveiled the next-generation A13 process, delivering a direct upgrade with a more streamlined, efficient design to meet the growing demand from next-generation AI, high-performance computing (HPC), and mobile applications.

Taiwan-based PCB maker Zhen Ding Tech has stated that as customers' next-generation product platforms gradually enter mass production starting from the second quarter of 2026, its IC substrate, server, and optical communications businesses are entering a new round of high-speed expansion. The company targets mid-to-high double-digit revenue growth for the full year of 2026 and is optimistic that shipment momentum will follow a quarter-on-quarter growth trend.

Growing pressure from capacity expansion in China, price competition, and compressed profit margins for traditional display applications has prompted Taiwan-based polarizer manufacturers to accelerate their transformation. Companies including BenQ Materials, Cheng Mei Materials Technology (CMMT), and Optimax Technology are diversifying their roles across medical, semiconductor materials, and automotive applications. Their objective is to mitigate industry risk and obtain a second growth curve.

Taiwanese printed circuit board (PCB) giant Zhen Ding Technology Group held a groundbreaking ceremony for the HD Campus of the "Zhen Ding Technology Group Huai'an Tech City" in Huai'an, China, on April 22. The new park plans to build facilities for high-density interconnect (HDI), modified semi-additive process (mSAP), and high-layer count (HLC) PCBs. Upon completion, the group's total number of factories across four major local parks will reach 23, further strengthening its manufacturing scale in the advanced PCB sector.

SK Hynix has broken ground on a large-scale advanced packaging facility in Cheongju Technopolis, underscoring how the battleground for AI semiconductors is shifting beyond wafer fabrication to the back-end processes that increasingly define performance.
