Location: United States
Workplace: Onsite
Employment Type: Full time
Job Function: Communications, PR & Community
Seniority: Mid level

Key Responsibilities

  • •Use lithography simulation software (e.g., Prolith, S-Litho) to analyze process windows and optimize patterning results.
  • •Apply advanced metrology (CD-SEM, Overlay, Scatterometry) to identify defects and improve Critical Dimension Uniformity (CDU) and overlay performance.
  • •Analyze process data to identify root cause and implement robust process improvements using SPC and DOE to enable litho shrink processes.
  • •Work with equipment vendors to evaluate new materials, photoresists, and tool hardware upgrades.
  • •Lead development of next-generation litho shrink processes for 20nm-class logic nodes, including litho-etch integration (LE/LELE/SADP/pitch doubling), RET/OPC strategies, materials selection, defect characterization, and collaboration with etch and cross-functional teams.

Key Requirements

  • •Master’s degree in Electrical Engineering, Materials Science, Physics, or a related discipline.
  • •5+ years of industry experience in advanced semiconductor process development.
  • •Hands-on experience with 22nm node or comparable advanced nodes (e.g., 28nm, 14nm).
  • •Strong expertise in photolithography process development/optimization, litho-etch integration (LELE, SADP, pitch splitting/doubling), OPC and RET methodologies, and dry etch pattern transfer.
  • •Deep understanding of critical dimension (CD) control and uniformity, overlay and alignment challenges, and defectivity mechanisms/mitigation.
