Introduction As a Lithography Process Engineer , you will be responsible for sustaining, optimizing, and developing photolithography processes in a high-volume manufacturing environment. You will work with advanced lithography tools and metrology systems to ensure critical dimension (CD) control, overlay accuracy, and defect reduction. Your Job Monitor and analyze SPC/ESPC charts for lithography modules using SPACE; respond to OOC/OOS events. Perform critical dimension (CD) and overlay analysis using CD-SEM, scatterometry, and overlay metrology tools (e.g., KLA, ASML YieldStar). Optimize photoresist coating, soft bake, exposure, post-exposure bake (PEB), and development processes. Manage and tune stepper/scanner exposure tools (e.g., ASML, Nikon) for optimal performance and tool matching. Conduct Design of Experiments (DOE) and split lot analysis using JMP, Klarity ACE, and other statistical tools. Troubleshoot lithography defects such as bridging, footing, scumming, and resist residues.
