Week In Review: Semiconductor Manufacturing & Test


The Biden Administration’s export bans for semiconductor manufacturing equipment are delaying expansion plans for Chinese chipmakers, Nikkei Asia reports. Yangtze Memory Technologies (YMTC) has halted work on its second memory plant near Wuhan, and ChangXin Memory Technologies (CMTX) says its second production facility, slated to open in 2023, will be delayed until 2024 or 2025. In an effo... » read more
