US firm AXT applying for permits after China restricts chipmaking exports

US semiconductor wafer maker AXT Inc mentioned on Monday it will search permits to maintain exporting gallium and germanium substrate merchandise from China, after Beijing abruptly imposed export controls on the metals key to chipmaking.

Germanium can be utilized in infrared expertise, fibre optic cables and photo voltaic cells. Jefferies analysts mentioned in a notice China managed 80% of world output of the supplies and that they noticed this as China’s second and far greater countermeasure within the US-China tech warfare, after Beijing banned some home sectors from buying merchandise from US reminiscence chipmaker Micron in May.

The controls are additionally probably a response to a possible U.S. tightening of an AI chip ban, the analysts mentioned.
