Job Responsibilities

Process Development & Optimization
You'll own lithography development for advanced packaging solutions.
Developing manufacturable, repeatable, and high-yielding processes.
Improving processes for cost reduction, cycle time reduction, and yield enhancement.
Collaborating with cross-functional teams to lead innovations in lithography and their implementation efforts
Drive the industry with advanced lithography solutions, for panel lithography

Equipment & Tooling Support
Active part of defining lithography equipment specifications and validating tools.
Work with cross-functional team to monitor and maintain tool performance.

Yield & Quality Improvement
Implement and refine process monitoring techniques and defect inspection, to proactively investigate and resolve lithography defects.
Collaborate with upstream and downstream process owners (e.g., plating, deposition, etching) to ensure seamless integration.
Support the development of process flows for advanced packaging substrates.

Data Analysis & Documentation
Perform statistical analysis (e.g., DOE, SPC) to identify and control critical process parameters.
Document standard operating procedures (SOPs), work instructions, and control plans.

Cross-Functional Collaboration
Work closely with design, product engineering, equipment vendors, and manufacturing teams to support process scale-up and new product introduction (NPI). Process Integration
Assist with customer qualifications and reliability testing as needed.

Perform any other ad-hoc duties as assigned by the Manager, as required to support the team and organizational goals.
