Onsemi buys SiC-supplier GT Advanced Technologies for $415m
Deal for SiC material supplier reinforces onsemi's move into electric vehicles (EVs), EV charging and energy infrastructure

Onsemi has bought GT Advanced Technologies, a producer of silicon carbide (SiC), for $415m in cash.

Founded in 1994, GTAT has significant experience in crystalline growth, including SiC. SiC is a key material for next-generation semiconductors that provide technical benefits in SiC power switching devices, significantly improving system efficiency in electric vehicles (EVs), EV charging and energy infrastructure.

The move is part of industry consolidation to secure supply of SiC materials. This includes deals by ST and Infineon with Cree and Rohm and II-VI buying European SiC wafer maker Ascatron
