Senior SiC EPD Engineer - Bucheon-si, Gyeonggi-do, Korea, Republic of, South Korea
Originally posted 19 August 2026 by the employer.
This role focuses on SiC power MOSFETs.
About the role
This role involves developing new products on SiC technologies and addressing device and process weaknesses in early manufacturing stages.
What you'll do
- Plan, manage, and execute engineering lots and DOE activities.
- Act as a SiC process integration lead engineer for device development.
- Perform yield analysis related to SiC material defects and fab-induced defects.
- Lead TCAD simulations to verify and optimize Silicon and SiC device technologies.
- Utilize layout tools (Cadence Virtuoso) to support device layout review, test structure definition, and design-process interaction analysis.
- Collaborate closely with Device, Process, Yield, Reliability, Manufacturing, and external partners.
What you'll need
- Master’s degree or higher in Engineering (Electrical Engineering, Materials Science, Physics, Semiconductor Engineering, or related field).
- Strong understanding of material science and device physics, including semiconductor fabrication and electrical characterization principles.
- Solid experience in SiC or HV Silicon device/process development, yield engineering, or defect analysis.
- Strong analytical and problem-solving skills.
- Strong communication skills in English, both written and verbal.
- Demonstrated technical leadership or mentoring experience.
Nice to have
- Hands-on experience with SiC epitaxial or material defect analysis and yield improvement.
- Proficiency in TCAD simulation tools and statistical analysis (DOE, SPC, correlation analysis).
- Experience with power MOSFET device layout and test structure design.
- Prior experience supporting technology ramp-up or high-volume manufacturing.
Skills: SiC process integration, SiC material defects, TCAD simulations, SiC device technologies, power MOSFET
