Location: Alhambra, CA

Position Summary: Wafer Fab Operator Level 1 (Op1) or Level 2 (Op2) is responsible for execution of wafer fabrication processes in an InP-based photonics manufacturing environment. This role supports the production of lasers, gain chips, and other III-V photonic devices by operating advanced semiconductor equipment, maintaining process control, and ensuring high-quality wafer output.

The operator position works with moderate supervision and contributes to process consistency, WIP flow, and yield protection by minimizing contamination, handling damage, and process deviations.

Responsibilities:

Wafer Processing & Equipment Operation (50%):

• Perform routine wafer fabrication steps following SOPs:
  • Wet cleaning and chemical processing (acid/base handling)
  • Photoresist coating (spin coating, soft bake)
  • Thin film deposition and dry etch (PECVD, RIE)
• Load/unload wafers into process tools and carriers
• Ensure correct recipe selection and lot processing sequence
• Follow process travelers and MES instructions precisely
• Execute process steps according to SOPs and process recipes
• Perform wafer handling with high care to prevent damage or contamination

Wafer Inspection, Process Monitoring & Quality Control (30%):

• Monitor critical process parameters (temperature, pressure, gas flow, alignment accuracy)
• Perform in-process inspections:
  • Optical microscope inspection
  • Film thickness/index/stress measurement (profilometer/ellipsometer/flexus)
• Identify abnormal conditions and deviations from process specs
• Escalate issues to Op3 or Technician as needed

Data Recording & Documentation (10%):

• Record process data, tool usage, and lot completion in logs or MES
• Document deviations or abnormalities during processing
• Ensure traceability of all processed wafers

Continuous Improvement & Engineering Support (10%):

• Assist in engineering runs, DOE experiments, and process qualifications
• Provide feedback on process issues and yield trends
• Support implementation of process improvements

Education and Experience:

• High school diploma or equivalent (required)
• Associate degree in electronics or related field (preferred)
• For Op1 , 0–1 year experience in semiconductor wafer fab or cleanroom manufacturing environment (preferred but not required)
• For Op2, 2–3 years of experience in cleanroom environment for semiconductor wafer fabrication (III-V or photonics preferred)

Minimum Qualifications

• Technical Skills
  • Basic understanding of:
    • Cleanroom practices and contamination control
    • Chemical handling and safety
    • Wafer handling techniques
  • Ability to follow detailed SOPs and process instructions
• Behavioral Competencies
  • Strong attention to detail and discipline
  • Ability to follow instructions with high accuracy
  • Good teamwork and communication skills
  • Willingness to learn semiconductor and photonics processes
• Physical & Work Environment Requirements
  • Ability to work in a cleanroom environment for extended periods
  • Standing for long durations and performing repetitive tasks
  • Handling small, fragile wafers with precision
  • Ability to wear full cleanroom gown (including mask, gloves, and suit)
• Additional Requirements
  • Willingness to work shifts (day/night if required)
  • Compliance with all safety and operational procedures
