Originally posted 30 September 2026 by the employer.
This role leads the transfer and qualification of products on Samsung 28FDS FD-SOI process technology.
About the role
This role leads and manages the transfer and qualification of products on Samsung 28FDS FD-SOI process technology.
What you'll do
- Lead technical engagement with Samsung Austin and Samsung Korea teams, coordinating with Lattice foundry engineers.
- Drive foundry suppliers to meet company yield, quality, and reliability goals.
- Own end-to-end process transfer and qualification, including baseline qualification, process corner validation, and PVT characterization.
- Drive lot starts, wafer splits, and process window experiments; perform WAT analysis to validate process baselines.
- Own post-transfer sustaining activities including yield improvement, process window optimization, and SPC monitoring on production silicon.
- Analyze WAT, inline, and final test data to identify process drift, yield loss mechanisms, and reliability risks; drive root cause and corrective action.
What you'll need
- M.S. in Electrical Engineering, Materials Science, or related discipline.
- 10+ years of semiconductor process or foundry engineering experience.
- Hands-on experience with advanced CMOS or FD-SOI process technologies at 28nm node or below.
- Strong knowledge of FD-SOI device physics including back-bias tuning, body effects, leakage, and variability.
- Experience with product qualification and reliability testing (HTOL, TDDB, EM).
- Demonstrated experience with WAT parametric analysis, yield engineering, SPC, and failure diagnosis and analysis coordination.
Nice to have
- Direct experience with Samsung 28FDS FD-SOI process technology.
- Experience working with Samsung Foundry engineering or process teams.
- Prior Failure Analysis experience.
- Proficiency in JMP, Python, or equivalent tools for large-scale data analysis.
- Familiarity with Lattice FPGA architecture or programmable logic products.
