Location: Alhambra, CA (Onsite)

Position Summary:

The Wafer Fab Operator is responsible for independent 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 Op2 operator works with moderate supervision and plays a key role in process stability, yield improvement, and WIP flow management.

Responsibilities: Wafer Processing & Equipment Operation:

• Independently operate semiconductor equipment, including:
• Photolithography tools (spin coat, mask aligner, developer)
• Dry etch systems (ICP/RIE) and chemical wet etch stations
• Thin film deposition (PECVD, sputtering)
• Execute process steps according to SOPs and process recipes
• Perform wafer handling with high care to prevent damage or contamination
• Ensure proper lot tracking and movement through MES/travelers

Process Monitoring & Quality Control:

• 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

WIP Management & Documentation:

• Accurately record process data, equipment logs, and lot history
• Track wafer status and ensure correct process flow progression
• Support cycle time targets and prioritize lot movement

Continuous Improvement & Engineering Support:

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

Minimum Qualifications:

• High school diploma or equivalent
• Working knowledge of:
• Thin film deposition processes
• Dry and wet etching techniques
• Photolithography processes (coating, alignment, exposure, development)
• Familiarity with semiconductor process flow, especially for III-V / InP devices
• Ability to operate and troubleshoot fab equipment with minimal supervision
• Strong attention to detail and contamination control
• Ability to follow SOPs while recognizing abnormal conditions
• Experience with MES systems and electronic lot tracking
• Basic data recording and interpretation (SPC awareness preferred)
• Ability to work in a cleanroom environment for extended periods
• Handling of chemicals (acids, solvents) with proper safety procedures
• Handling fragile III-V wafers with precision
• Ability to wear full cleanroom gown (including mask, gloves, and suit)

Desired Qualifications:

• Associate degree in electronics, semiconductor manufacturing, or related field
• 2–3 years of experience in semiconductor wafer fabrication (III-V or photonics preferred)
• Experience in cleanroom environment (Class 100–1000)
• Good communication and teamwork
• Ability to work in a fast-paced production environment
• Strong sense of ownership and accountability
