The Role
Leads III-V optoelectronic product and process development from design through qualification and manufacturing ramp. Manages mask sets, process flows, BOMs, matrix lots, failure analysis, experiments, yield improvement, and cross-functional readiness. Requires a PhD and at least three years of semiconductor laser design, process development, and characterization experience, with expertise in devices such as VCSELs or DFB lasers, statistical analysis, wafer fabrication, and cleanroom operations.
Summary Generated by Built In
- Responsibilities
- Drive new product and new process development to ensure timely and successful delivery of qualified products.
- Oversee day-to-day progress of matrix lots to keep development activities on track.
- Manage part numbers and BOM to ensure proper setup for new product introduction.
- Support the NPI team in establishing mask sets, process flows, and workflows for both front-end (wafer fabrication) and back-end (die assembly and characterization) processes.
- Assist in failure analysis by investigating issues found during wafer fabrication and product characterization and take the lead in analyzing root causes.
