Introduction
As aLithography 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.
Collaborate with Equipment Engineers on tool qualification, focus-exposure matrix (FEM), and process window optimization.
Maintain and optimize reticle management, focus and exposure control, and alignment strategies.
Drive process improvements to enhance CD uniformity, overlay performance, line edge roughness (LER), and critical dimension uniformity (CDU).
Support technology transfers, new product introductions (NPI), and process ramp-up activities.
Lead cross-functional teams to resolve yield excursions and implement corrective/preventive actions (CAPA).
Ensure compliance with TS16949 and other quality standards through regular audits and documentation updates.

Other Responsibilities:

Perform all activities in a safe and responsible manner and support all Environmental, Health, Safety & Security requirements and programs

Required Qualifications

Bachelor Degree in Electrical / Electronics / Mechanical / Mechatronics / Microelectronics Engineering
1 to 3 years of relevant experience in semiconductor wafer process engineering
Proven ability to identify, assess and solve problems
Perform Normal / Swing Shift (or 12-hour rotating shift if required)
