OPC Verification Engineer

Job Title

OPC Verification Engineer

Role Summary

The OPC Verification Engineer develops and validates optical proximity correction (OPC) verification recipes and RET (Resolution Enhancement Techniques) flows to support advanced-node semiconductor lithography. The role works with circuit designers, fab engineers, lithography and yield teams to translate lithography requirements into code, tests, and verified outputs.

Experience Level

Mid-level. Requires significant hands-on experience in semiconductor photolithography and RET development; the posting specifies 5+ years of relevant experience.

Responsibilities

Primary responsibilities focus on implementing and validating OPC verification recipes, optimizing hotspot prediction, and collaborating across fabrication and design teams.

• Collaborate with designers and fab engineers to gather and clarify lithography and RET requirements.
• Translate lithography requirements into implementation plans for OPC verification (OPCV) recipe code.
• Write, maintain, and optimize OPCV-recipe code and parameters to improve hotspot prediction and reduce false errors.
• Create, execute, and maintain test cases for OPCV-recipe code.
• Review and analyze large RET-output layouts for quality and manufacturability.
• Interface with lithography, mask, and yield-enhancement teams to drive solutions and improvements.

Requirements

Must-have qualifications and technical skills required for the role, followed by preferred skills.

Must-have:

• 5+ years' experience in semiconductor photolithography or RET development.
• Demonstrated lithography and RET expertise for 45 nm, 28 nm, 22 nm and 20 nm technology nodes.
• Strong understanding of advanced lithography processes, lithography simulation techniques, mask making, and RET techniques used in semiconductor manufacturing.
• Experience translating lithography requirements into OPC/verification implementations and optimizing recipe parameters.
• Ability to create and execute test cases and review RET outputs for quality.

Nice-to-have:

• Experience with PLRC and ORC.
• Familiarity with physical layout formats and tools (OASIS, GDSII): viewing, measuring, and manipulating layout data.
• Experience with code version control (for example, Git).
• Strong analytical, problem-solving, verbal and written communication skills; ability to work in cross-functional teams and manage time to meet project deadlines.

Education Requirements

Master's degree in Electrical Engineering, Physics, Computer Science, Chemistry, or a related field is required (as stated in the posting).
