Senior/Staff Engineer-Lithography processes

• As a Senior/Staff Lithography Process Engineer, you will lead the development and optimization of lithography processes for both Fan-In and Fan-Out eWLB (Embedded Wafer Level Ball Grid Array) packaging technologies.
• You will be responsible for driving key engineering projects such as yield improvement, cost reduction, and process transfers across global manufacturing sites.

Key Responsibilities:

• Own and optimize lithography processes for PI, PR, and other patterning layers in both FO and FI eWLB.
• Manage photolithography tools (GHI/i-line stepper, coat/develop tracks, etc.), including recipe setup and troubleshooting.
• Lead cross-functional projects focused on cost reduction, process robustness, and NPI transfer.
• Lead process improvements to enhance yield, throughput, and cost efficiency.
• Evaluate and implement new lithography materials (PSPI, PR) and tools.
• Define and maintain process documentation (SOP, OCAP, FMEA, SPC) and training programs.
• Collaborate with equipment vendors, materials suppliers, and internal engineering teams to evaluate and qualify new tools or materials.
• Design and perform DOE, root cause analysis, and statistical data analysis (e.g., JMP, Camline, etc.).
