US President Donald Trump has blocked HieFo Corp.’s acquisition of semiconductor-related assets from Emcore Corp., citing national security concerns.
The order issued on Friday stated that Delaware-based HieFo Optoelectronics was formed and is controlled by a Chinese citizen. The order targets HieFo’s purchase of assets from Emcore, which include digital chips and related wafer design, manufacturing, and processing businesses.
In 2024, the two companies announced the completion of a $2.92 million (11.84 million MYR) deal for the sale of Emcore’s chip business and indium phosphide wafer manufacturing operations.
Trump said in the order that the deal might harm US national security, marking the administration’s latest move to crack down on China’s access to advanced semiconductor technology.
The order requires HieFo Optoelectronics to divest within 180 days unless the Committee on Foreign Investment in the United States (CFIUS) grants additional time.
