Process Engineer - Wet Etch, Clean & Stripping

Responsibilities:

· Develop, qualify, and maintain wet etch, clean, and stripping processes for semiconductor wafer fabrication and advanced packaging applications.

· Optimize process parameters to achieve target specifications for critical dimensions, surface cleanliness, and defect performance.

· Monitor process health through Statistical Process Control (SPC) and implement corrective actions when deviations occur.

· Investigate yield excursions, defects, and process abnormalities using root cause analysis methodologies.

· Design and execute experiments (DOE) to improve process performance, increase yield, and reduce manufacturing costs.

· Collaborate with Equipment, Production, Quality, Product Engineering, and R&D teams to resolve technical issues and support production goals.

· Support new product introductions (NPI), process transfers, and technology development activities.

· Evaluate and qualify new chemicals, materials, and process technologies.

· Prepare and maintain process documentation, including specifications, work instructions, FMEA, control plans, and qualification reports.

· Ensure compliance with Environmental, Health, and Safety (EHS) standards, chemical management procedures, and waste disposal regulations.

· Drive continuous improvement initiatives focused on yield enhancement, defect reduction, cycle-time improvement, and cost savings.

Requirements:

· Degree in Chemical Engineering, Materials Science, Chemistry, Semiconductor Engineering, or a related discipline

· Minimum 2 years of experience in semiconductor manufacturing, preferably in wet etch, cleaning, stripping,  plating, or wafer-level packaging processes

· Strong understanding of semiconductor process integration and wet chemical processing

· Knowledge of chemical compatibility, contamination control, and surface preparation techniques

· Experience with DOE, SPC, FMEA, CAPA, and statistical data analysis tools such as JMP or Minitab

· Familiarity with wet process equipment, automated wet benches, and chemical delivery systems.

· Strong analytical, troubleshooting, and problem-solving skills
