DFM and Yield-Aware Design Engineer

Project

Work done for a product or program.

• Run litho simulation and hotspot detection on final layout using Calibre LFD or equivalent process-window models.
• Fix printability hotspots by re-routing, spacing adjustment, and pattern modification in cooperation with PD teams.
• Perform CMP and planarity simulation to identify topography risk and adjust fill density distribution accordingly.
• Apply critical area analysis to quantify random defect yield loss and reduce it via wire spreading and via doubling.
• Increase via redundancy and reduce single-via and minimum-area constructs across the design.
• Work with the foundry yield team to interpret inline defect data, kill ratios, and systematic failure signatures.
• Feed DFM-driven constraints into the P&R flow as NDR, spacing tables, and density targets so fixes are designed in.
• Analyse test-chip and product yield data to identify layout-dependent systematic yield detractors.
• Publish DFM signoff scorecards and define the manufacturability acceptance criteria per product.

Function

Work that keeps the discipline running: methods, tools, suppliers and people.

• Implement recommended-rule compliance scoring and drive tradeoffs between recommended rules and area or timing cost.
