Unit Process Development Engineer for CMP

Bucheon-si, South KoreaFull-timePosted Jul 16, 2026

onsemi is seeking a Unit Process Development engineer (CMP) for wide bandgap technology ramp to drive fast ramp of new technologies without quality issue in manufacturing factories for wide band gap technologies. These engineers will need to work with process integration engineering team, device team, package development, product engineering from fab tool selection, module unit process development, process integration flow, to enable new technologies and new products meeting customer requirement, manufacturability, high quality, and fast time to market delivery. 

 

These are “hands on” positions. The successful candidates are expected to be able to work independently as well as within teams.  They should possess analytical skills to identify problems, the leadership skills to own and drive improvement across all aspects of new technology from feasibility to production ramp.
