Compound semiconductor supply-chain players say China has recently eased some substrate export controls, but the upgrade of high-frequency transmission in AI data centers toward 200G and 400G has made optical communications a key technology breakthrough, creating a severe indium phosphide (InP) substrate shortage and sparking a trend toward signing long-term contracts and locking up capacity to secure stable supply.

Surging AI chip demand continues to outstrip TSMC's advanced packaging capacity. At the same time, massive AI server shipments are driving up demand for CPUs, networking equipment, power management ICs (PMICs), and peripheral silicon, rapidly soaking up traditional packaging capacity. IC design insiders reveal that several outsourced semiconductor assembly and test (OSAT) providers have already warned clients that traditional packaging capacity could face a deficit exceeding 20% by 2027. New capacity cannot be added quickly enough, with the supply of wire bonding equipment emerging as the primary bottleneck.

SK Hynix is weighing closer cooperation with Japan's Kioxia Holdings in NAND flash, extending the strategic message from its newly launched US HBM expansion into a memory segment where the two companies remain direct competitors.

Competition in China's memory sector is extending beyond wafer capacity and process technology into semiconductor equipment, materials and components. YMTC is expanding its domestic supplier network around its Wuhan fabs, with 17 semiconductor companies signing projects worth more than CNY6 billion in the Wuhan Donghu New Technology Development Zone (China Optics Valley).

Vanguard International Semiconductor said a fire broke out late on August 27 on the roof of its Wafer Fab 3 in Taoyuan City, Taiwan, but the incident caused no major impact on production line operations. The company said it activated emergency procedures immediately and evacuated employees from the plant.

Lam Research has begun work on a new Oregon research lab as part of a more than US$3 billion global investment aimed at speeding development of advanced AI chips. The expansion could affect semiconductor supply chains, innovation timelines, and manufacturing capacity for companies and consumers worldwide as demand for faster, more efficient computing rises.

Renesas Electronics has opened a physical AI and robotics lab in Beijing, a move that could speed the development of safer, smarter machines for factories, logistics, and homes worldwide. The facility is designed to help customers test, validate, and co-develop robotic systems as physical AI shifts from concept to real-world deployment.

Marvell Technology used its second-quarter fiscal 2027 earnings call on August 27 to lift its revenue outlook for a second consecutive quarter, and the composition of the raise says more about the AI infrastructure cycle than the headline number does. Management now expects fiscal 2027 revenue of roughly US$12 billion, up from approximately US$11.5 billion a quarter ago, and fiscal 2028 revenue of approximately US$18 billion, up US$1.5 billion from the US$16.5 billion guided three months earlier. Growth is accelerating off a larger base: fiscal 2028 is now guided at about 50% growth, up from roughly 45% previously.

A major chipmaking investment in Japan could ripple through global supply chains as demand for artificial intelligence infrastructure accelerates. Kioxia and Sandisk say the spending will expand flash memory output, support stable supply, and reinforce a long-running US-Japan partnership in advanced semiconductor manufacturing.

SK hynix broke ground on August 27 on a US$4 billion advanced packaging plant in Purdue Research Park, its first US high-bandwidth memory (HBM) site.

Marvell Technology's second quarter of fiscal 2027 was the point at which its data center business stopped being the growth engine attached to a diversified infrastructure chipmaker and became substantially the whole company. Revenue for the three months ended August 1, 2026, reached a record US$2.74 billion, up 37% from a year earlier, with the data center end market contributing US$2.17 billion, or 79% of the total, against 74% a year ago. Everything else - the carrier, enterprise networking, consumer, and automotive businesses grouped as communications and other - grew 10% and shrank as a share of the company.
