Job description

Location: Alhambra, CA
Position Summary: The Backend Process Engineer - InP Wafer Fab position is responsible for development, optimization, and manufacturing support of backend wafer fabrication processes for Indium Phosphide (InP)-based photonic devices, including DFB lasers, Semiconductor Optical Amplifiers (SOAs), and Gain Chip products. This role provides technical ownership of critical backend modules including wafer lapping/thinning, n-side metallization, rapid thermal annealing (RTA), and automated optical inspection (AOI). The position also supports singulation, optical coatings, reliability readiness, and packaging interfaces, with a strong focus on yield, defect reduction, and manufacturing stability.
Responsibilities:
Backend Process Ownership and Optimization (35%):
  • Own and optimize backend wafer fab processes including lapping/thinning, n-side metallization, and RTA

  • Establish robust process windows, recipes, and control limits for backend modules

  • Maintain stable manufacturing performance through continuous monitoring and improvement

Yield Improvement, Defect Reduction, and AOI Control (25%):
  • Own and maintain AOI processes for backend defect detection and yield monitoring

  • Drive singulation yield improvement and defect reduction through data analysis and root-cause investigations

  • Analyze inline and post-process data to identify trends and systematic issues

  • Implement corrective and preventive actions and verify effectiveness

Singulation, Optical Coatings, and Packaging Interface Support (20%):
  • Support cleaving, dicing, and singulation processes to ensure device integrity

  • Provide process engineering support for AR/HR optical coatings and vendor qualifications

  • Collaborate with packaging, device, and reliability teams to ensure packaging readiness

New Product Introduction and Technology Support (10%):
  • Support new product introduction (NPI), process transfers, and technology changes

  • Evaluate backend process risks associated with new designs, materials, and device structures

Documentation, Process Control, and Manufacturing Support (10%)
  • Author and maintain SOPs, travelers, process specifications, and control plans

  • Define SPC metrics and control strategies for backend processes

  • Provide hands-on manufacturing and troubleshooting support as needed

Minimum Qualifications:
  • Bachelor's degree or higher in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or a related field

  • Minimum of 3+ years of experience in backend semiconductor processing

  • Hands-on experience with lapping/thinning, metallization, and thermal processes

  • Understanding of InP-based or III-V compound semiconductor wafer fabrication processes

  • Experience with AOI systems, yield analysis, and data-driven process improvement

  • Strong understanding of singulation, packaging interfaces, and reliability requirements

  • Proficiency in SPC, DOE, and statistical analysis

  • Ability to work across cross-functional manufacturing and engineering teams

  • Preferred experience with InP or III-V optoelectronic devices

  • Familiarity with AR/HR optical coating processes

  • Experience supporting high-mix, low-volume manufacturing environments preferred
