TAIPEI/SEOUL -- Top chipmakers in Taiwan and South Korea are closely reviewing their stockpiles of critical industrial gases after Russia's invasion of Ukraine sparked fears of supply disruption that could exacerbate a global chip shortage.
Taiwan Semiconductor Manufacturing Co. and United Microelectronics Corp. -- the world's largest and fourth-largest contract chipmakers, respectively -- spoke with key gas suppliers on Thursday to make sure supplies would continue to be available, according to multiple sources familiar with the matter.
