Primary Duties & Responsibilities
✅ Process Development and Optimization
- Develop and optimize thin-film deposition processes using sputtering, evaporation, and RTP to meet performance and yield targets.
- Establish process parameters for GaAs and InP substrates, monitor equipment performance, and implement corrective actions as needed.
- Collaborate with integration to transfer new processes into production.
- Develop and maintain in-line and offline metrology techniques to characterize thin films on GaAs and InP substrates (e.g., thickness, uniformity, stress).
- Use tools such as ellipsometry, profilometry, X-ray diffraction (XRD), and atomic force microscopy (AFM) to measure and analyze film properties.
- Monitor statistical process control (SPC) charts and drive corrective actions to minimize variation.
- Serve as the technical expert for sputter, evaporation, and RTP tools used for processing III-V compound semiconductors (e.g., GaAs and InP).
- Lead troubleshooting efforts for process deviations and equipment issues.
- Partner with equipment vendors and internal maintenance teams to improve tool performance and uptime.
- Conduct failure analysis and defect characterization on GaAs and InP substrates to identify root causes of process variation.
- Implement process improvements to enhance yield and reduce defectivity.
- Lead continuous improvement initiatives to enhance productivity and process robustness.
- Develop and maintain process documentation, including work instructions, FMEA, and control plans.
- Train process technicians and junior engineers on best practices and troubleshooting techniques.
- Bachelor's or Master's degree in Materials Science, Electrical Engineering, Chemical Engineering, Physics, or related field.
- 5 years of experience in semiconductor process engineering, with a focus on thin-film deposition and RTP on GaAs and InP substrates.
- Hands-on experience with:
- Sputtering (DC, RF, and reactive) on compound semiconductors
- Evaporation (thermal, electron beam)
- Rapid Thermal Processing (annealing, oxidation) for GaAs and InP
- Strong background in process metrology, including experience with:
- Ellipsometry
- XRD
- AFM
- SEM (Scanning Electron Microscopy)
- Profilometry
- Proficiency with statistical analysis tools (e.g., JMP) and SPC methods.
- Fluency with MS Office suite.
- Strong problem-solving and root cause analysis skills.
- Excellent written and verbal communication skills.
- Experience with process integration in a high-volume manufacturing environment.
- Familiarity with defect analysis and classification techniques (e.g., KLA inspection).
- Will be exposed to areas where hand tools and power tools are being operated
- Will be exposed to areas where hazardous chemicals or gases are stored
- Ability to work in a cleanroom environment per semi-conductor protocol/requirements
- Work in a class 100/1000 clean room for extended periods
- Wear full cleanroom attire (smock, mask, etc.)
- Work with and/or around chemicals (such as solids and acids)
- Stand for up to 4 hours at a time
- Lift up to 16-30 Pounds
- Push/Pull up to 16-30 pounds
- Sit for up to 4 hours at a time
