A former researcher at Samsung Electronics was sentenced to seven years in prison on April 22 by a South Korean court for leaking core semiconductor trade secrets to a Chinese competitor. The case highlights how chip-making technology is increasingly regarded by governments as a national security asset under strict protection.

SK Hynix said it plans to expand production of its latest 321-layer NAND chips, as demand for AI applications leads to increased adoption of high-capacity enterprise storage.

SK Hynix said demand for high-bandwidth memory is expected to outpace supply for several years, underscoring persistent constraints in the AI memory market even as the company ramps up investment.

Parade Technologies' first-quarter 2026 results and revised outlook carry broader supply-chain and demand implications for global PC and electronics markets. Memory shortages and price hikes are depressing PC shipments, while the company pivots into automotive, data-center, and other non-PC segments to offset anticipated declines through the rest of 2026 and beyond.

Tesla plans to use advanced semiconductor manufacturing technology from Intel in its ambitious Terafab project, a development that could mark a significant milestone in Intel's efforts to re-establish itself as a leading global chip foundry.

Driven by strong artificial intelligence (AI) and silicon photonics (SiPh) demand, optical communications epitaxy manufacturer LandMark Optoelectronics reported a more than sixfold increase in net profit in the first quarter of 2026, with earnings per share (EPS) reaching NT$3.44 (approx. US$0.11). The company's board also approved a five-year supply agreement with Japan's Sumitomo Electric Industries for indium phosphide (InP) substrates to ensure stable access to this critical raw material.

As the artificial intelligence boom reshapes global computing demand, the memory chip industry is entering a new phase of strain and restructuring — one in which both DRAM and NAND flash are seeing rapidly tightening supply.

TSMC is accelerating its advanced packaging expansion in the US while maintaining a conservative stance on next-generation lithography, as the company balances cost pressures, AI-driven demand, and long-term manufacturing diversification. Analysts say the dual strategy highlights how advanced packaging and tool selection are becoming just as strategically important as leading-edge wafer production in shaping the global semiconductor supply chain.

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.
