DFM / OPC Engineer

Shape what actually gets built—not just what gets designed.

A major IC manufacturer is building the next generation of 28nm analog and embedded technologies, and they need engineers who understand a critical truth:

At advanced nodes, designs don’t fail in theory—they fail in manufacturing.

This role sits at the center of that problem.

🚀 Why This Role Stands Out

• Direct impact on silicon yield before tapeout
• Work on computational lithography + OPC + DFM at scale
• Influence every product that goes into production
• Operate at the intersection of design, lithography, and process integration
• Be part of a team enabling millions of chips produced daily
• You’re not supporting manufacturing—you’re making it possible

🔧 What You’ll Work On

At 28nm and below, optical distortion breaks intended designs—and fixing that is the job.

You will:

• Develop and optimize OPC models and RET strategies
• Identify and eliminate lithography hotspots and yield limiters
• Drive DFM methodologies that ensure designs print correctly the first time
• Collaborate with design, lithography, and process teams to co-optimize layouts
• Analyze wafer data and yield signatures to solve patterning challenges
• Build and improve automation flows for OPC/DFM
• Help define next-generation manufacturability standards

🧠 What “Good” Looks Like

You likely come from one of these backgrounds:

• OPC / Computational Lithography
• DFM / Yield Engineering
• Physical Design with strong DFM exposure



And you bring:

• 5+ years in OPC / DFM within semiconductor manufacturing
• Deep understanding of lithography + RET (OPC, assist features, etc.)
• Experience with tools like:
• Synopsys (Sentaurus Lithography)
• Siemens EDA (Calibre)
• ASML Brion
• Familiarity with 28nm / advanced node constraints
• Scripting experience (Python, TCL, Perl)

💡 Nice to Have (Differentiators)

• Analog layout + DFM interaction experience
• Exposure to Cadence Virtuoso, DRC/LVS flows
• Experience applying ML/AI to lithography or DFM problems
• Strong cross-functional influence (design ↔ fab)

🎯 The Real Opportunity

This is a high-leverage role:

• Your work determines whether designs become manufacturable products
• You influence yield, cost, and scalability at production volume
• You operate in a space where few engineers have deep expertise

If you’ve worked in OPC, lithography, or DFM, you already know: This is where the hardest—and most valuable—problems are solved.

📍 Additional Details

• Advanced Technology Development environment
• Strong cross-functional exposure
• High visibility within engineering and manufacturing teams
• Long-term impact on high-volume production platforms
