China's Yangtze Memory Technologies (YMTC) is expanding its memory production with plans for two new fabs in Wuhan, in addition to the Phase 3 plant set to be completed this year. Each new plant will have the capacity to produce 100,000 wafers per month, doubling YMTC's current output. With over 50% of Phase 3's equipment sourced domestically, YMTC is testing the viability of Chinese chipmaking tools for high-volume 3D NAND production. The company aims to increase DRAM and NAND production, with a focus on developing through-silicon via packaging for high-bandwidth memory. Despite challenges, YMTC holds a significant share of the global NAND market and is projected to grow further by 2028.

ASML's roadmap for chipmaking lithography tools examined — from DUV to Low-NA, High-NA, Hyper-NA, and beyond

ASML's roadmap for chipmaking lithography tools covers four generations of technology: DUV immersion, low-NA EUV, High-NA EUV, and a Hyper-NA concept for the 2030s. Each generation offers finer resolution at higher costs and complexity, impacting the pace of transistor scaling. TSMC opts for low-NA EUV for its upcoming nodes, while ASML's High-NA tools are being adopted by Intel, Samsung, and SK hynix. The company's roadmap includes advancements in resolution and throughput, with a focus on High-NA and future Hyper-NA systems. Challenges like pellicle development and export controls shape the landscape of lithography technology adoption.

Samsung engineer sentenced to 7 years in prison for selling chipmaking trade secrets to Chinese chipmaker — ex-employee supplied 10nm DRAM data to CXMT for $2 million

A Samsung engineer has been sentenced to seven years in prison for selling chipmaking trade secrets to Chinese chipmaker CXMT. The engineer, known as "Jeon," supplied detailed steps on DRAM manufacturing to CXMT for $2 million, causing potential trillions in losses for South Korea. Jeon's low compensation at Samsung was considered a mitigating factor in the sentencing. The stolen information allegedly helped CXMT advance its technology, leading to concerns about lost sales for Samsung and potential national security implications. The incident highlights the ongoing challenges of protecting intellectual property in the tech industry.

Chinese fabs import record volumes of US chipmaking equipment via Singapore and Malaysia — homegrown tool makers booked record 2025 revenues as price competition squeezes margins

Chinese fabs import record volumes of US chipmaking equipment via Singapore and Malaysia — homegrown tool makers booked record 2025 revenues as price competition squeezes margins

Chinese chipmaking equipment firms Naura, AMEC, ACM Research, and Piotech saw record revenues in 2025, driven by Beijing's push to reduce reliance on imported wafer fab equipment. Chinese fabs are importing US-branded tools via Singapore and Malaysia, reducing direct imports from the US. However, price competition among Chinese vendors is squeezing profit margins. The MATCH Act aims to restrict Southeast Asian routing to China, targeting key components and specific Chinese chipmakers. US lawmakers are working to limit exports of chipmaking tools to leading Chinese firms.

YMTC's third Wuhan fab clears Beijing's 50% local tooling threshold as two more are planned — move positions company toward 3D NAND production to capitalize on wafer bonding strengths

YMTC's Phase 3 Wuhan fab is set to open later this year, meeting Beijing's requirement for new Chinese fabs to source at least 50% of their equipment domestically. The company plans to add two more fabs of similar scale in the future. The move towards 3D NAND production leverages China's strengths in wafer bonding technologies. Despite reliance on imported lithography tools, YMTC aims to achieve 50% domestic tooling by substituting in other areas like etch, deposition, and cleaning. Additionally, part of the new fabs' capacity will be allocated to DRAM production, with YMTC making strides in developing its own DRAM technology.
