Purpose of the Job:
  • To support R&D activities for 2.5D wafer-level packaging (WLP) processes-including Die Preparation, Chip Attach, and Mold-focusing on process reliability, manufacturability, and integration for advanced semiconductor packages.

Key Job Accountabilities:
  • Develop and optimize key 2.5D CoW (Chip-on-Wafer) processes: Die Preparation: grinding, laser grooving, dicing saw Chip Attach: TCB (Thermo-Compression Bonding), LCB (Laser Compression Bonding) Mold: compression or transfer mold for warpage and protection
  • Perform material evaluation and reliability analysis (e.g., XRF, shear test)
  • Conduct DOE/FMEA for robust process design and improvement
  • Work closely with cross-functional teams (e.g., Bumping, RDL, Failure Analysis) to enable seamless process integration
  • Track and analyze industry trends in equipment, materials, and technologies
  • Support new product introduction (NPI) and yield ramp-up through structured problem-solving
  • Document process flows, risk assessments, and engineering reports

Scope of the Job:
  • Directly impacts production readiness, yield, and reliability of high-value 2.5D packages
  • Supports NPI for advanced semiconductor customers (e.g., AI, HPC, and memory applications)
  • Influences supplier qualification and capital decisions related to 2.5D tooling and materials
  • Contributes to revenue generation through early ramp-up and stable process delivery

Required Experience and Qualifications:
  • Bachelor's degree or higher in Engineering (Materials, Electronics, Chemical, Mechanical, or related field)
  • 3+ years of hands-on experience in semiconductor packaging process development (Die Prep, Chip Attach, or Mold)
  • Proficient in DOE, FMEA, statistical process control, and failure analysis
  • Familiar with process and reliability evaluation tools (e.g., XRF, shear test, SAM)
  • Skilled in documentation and cross-functional communication
  • Experience in OSAT, Fab, or advanced packaging (e.g., 2.5D/3D, HBM, interposer) (Preferred)
