onsemi is seeking a Device Engineer to join the Device Engineering / Yield Enhancement group in Gresham, OR. You will work with engineers and technicians in a fast-paced silicon wafer fabrication production and technology development environment, supporting primary technology nodes from sub-0.18µm to 0.5µm.
The role encompasses yield enhancement at both wafer and die levels, technology transfers, new product introduction, and production sustaining/optimization activities. You will build semiconductor device knowledge across the entire silicon manufacturing chain—from bare wafers to finished goods—with significant focus on fab manufacturability.
Key responsibilities include:
- Yield enhancement for production products and new product introduction into the fab
- Scrap reduction and prevention through process improvements
- Working directly with Process Engineering to implement improvements using existing and newly acquired equipment
- Minimizing variation (lot-to-lot, wafer-to-wafer, product-to-product)
- Reducing cost, improving throughput, and lowering defectivity
- Standardization and best-known-methods development
- Analyzing manufacturing and test data to improve product performance
- Ensuring all shipped material meets requirements
- Presenting trends, KPIs, and process improvements to management
You will regularly interface with in-house Fab Process Engineering, Technology Development, Failure Analysis, Design/Layout, wafer probe/test, in-line defect control, Quality, and Business Unit stakeholders. Strong communication skills are essential.
