Engineer (Front Assembly Line)

To develop, optimize, qualify, and establish robust semiconductor assembly processes for semiconductor packages, covering multiple assembly processes from wafer preparation to final assembly cleaning. The role is responsible for process development, optimization, qualification, technical problem-solving, and manufacturing readiness to ensure new products meet quality, reliability, productivity, and cost requirements.

The engineer will work closely with NPI project management, Production, Process Engineering, Equipment Engineering, Quality Assurance, Product Engineering, Material Engineering, and other cross-functional teams to ensure successful product introduction and smooth transfer to mass production.

Key Responsibilities

A. NPI Process Development and Qualification

• Develop, establish, and optimize assembly process conditions for new products.
• Prepare and execute process development plans, engineering & qualification builds, and process validation activities.
• Establish process parameters, specifications, control limits, and acceptance criteria.
• Evaluate process feasibility, identify potential manufacturing risks, and implement preventive actions before mass production.
• Review process capability, yield performance, defect trends, and qualification results.
• Prepare technical reports, process documentation, and qualification summaries.
• Support safe launch activities and ensure all critical process issues are resolved before mass production release.
B. Multi-Process Engineering Responsibilities

• Plasma Cleaning - Develop and optimize Plasma cleaning process for Pre and Post Wire Bond.
• Wire Bonding - Develop and optimize wire bonding process applicable process parameters and tools & jigs.
• AP Coating & bake - Develop and optimize AP coating and baking processes.
C. Cross-Functional Collaboration

• Collaborate with Production, Equipment Eng, QA, Product Eng, Material Eng, and other relevant departments
• Work with equipment and material suppliers to evaluate new technologies and improvement opportunities.
• Provide technical support during engineering builds, qualification builds, troubleshooting, and production ramp-up.
• Coordinate process readiness, material availability, and documentation before qualification and mass production.
D. Documentation and Mass Production Transfer

• Prepare and maintain process specifications, SOPs, work instructions, process flow documents, and risk assessments.
• Maintain engineering records, process parameter histories, DOE results, and qualification reports.
• Support PFMEA reviews and implementation of appropriate process controls.
• Define critical-to-quality parameters and monitoring requirements.
