Summary

The WLP Development Engineer will support R&D and process integration activities for 2.5D wafer-level packaging (WLP) technologies, focusing on Die Preparation, Chip Attach, and Molding processes. The role ensures process reliability, manufacturability, and seamless integration for next-generation semiconductor packages used in AI, HPC, and memory applications.

Key Responsibilities

• Develop and optimize Chip-on-Wafer (CoW) processes:
• Die Preparation: grinding, laser grooving, dicing saw
• Chip Attach: Thermo-Compression Bonding (TCB), Laser Compression Bonding (LCB)
• Mold: compression or transfer molding for warpage control and chip protection
• Perform material evaluations and reliability analyses (e.g., XRF, shear test, SAM).
• Design and execute DOE and FMEA to ensure robust process control and yield improvement.
• Collaborate cross-functionally with Bumping, RDL, and Failure Analysis teams for process integration.
• Monitor industry trends in equipment, materials, and 2.5D/3D packaging technologies.
• Support New Product Introduction (NPI) and yield ramp-up through structured problem-solving.
• Prepare and maintain process documentation, including flow charts, risk assessments, and engineering reports.
• Influence supplier qualification and capital equipment decisions related to 2.5D processes.
• Drive production readiness and contribute directly to yield, reliability, and revenue growth.

Requirements

• Bachelor’s degree or higher in Materials, Electronics, Chemical, Mechanical Engineering, or related field.
• Minimum 3 years of hands-on experience in semiconductor packaging process development (Die Prep, Chip Attach, or Mold).
• Strong knowledge of DOE, FMEA, SPC, and failure analysis methodologies.
• Familiarity with analytical and reliability tools such as XRF, shear test, SAM.
• Excellent documentation, data analysis, and cross-functional communication skills.
• Experience in OSAT, Foundry, or Advanced Packaging (2.5D/3D, HBM, Interposer) environments is preferred.

All Successful candidates can expect a very competitive remuneration package and a comprehensive range of benefits.
