Process Development Engineer (Epitaxy – III-V / MOCVD):
Responsible for the development, optimisation, and control of epitaxial growth processes for III-V semiconductor devices, with a strong emphasis on MOCVD (Metal-Organic Chemical Vapor Deposition). The role involves defining process parameters, improving yield and performance, and supporting high-volume manufacturing in a cleanroom environment.
Key Responsibilities
- Provide expert guidance on III-V epitaxial growth processes, with a focus on MOCVD systems.
- Develop, optimise, and sustain epitaxy processes for III-V materials (e.g., GaAs, InP-based structures).
- Lead continuous improvement initiatives using SPC and Six Sigma methodologies to enhance yield, uniformity, and device performance.
- Define and control critical process parameters (e.g., temperature, gas flow, pressure) for MOCVD growth.
- Support troubleshooting and fault-finding of epitaxy tools and processes, particularly MOCVD reactors.
Key Relationships
- Manufacturing Operations Team
- Epitaxy Equipment Engineering Team
- Epitaxy Process Engineering Team
- New Product Introduction (NPI) Team
Qualifications
- Degree in Semiconductor Physics, Materials Science, Electronic Engineering, or a related field.
- Minimum 3+ years of hands-on experience in III-V semiconductor processing, with a strong focus on epitaxy.
- Proven experience operating and developing MOCVD processes in a production or R&D environment.
- Demonstrated experience in process engineering and continuous improvement methodologies (e.g., Six Sigma, SPC).
Skills
Essential
- Strong expertise in III-V semiconductor materials and epitaxial growth mechanisms.
- Hands-on experience with MOCVD equipment and process development.
- Solid understanding of semiconductor fabrication processes and cleanroom practices.
- Experience with vacuum systems and computer-controlled processing equipment.
- Knowledge of Manufacturing Execution Systems (MES) and concepts such as SPC, scheduling, and rework procedures.
- Strong analytical and problem-solving skills, particularly in process optimisation and yield improvement.
Desirable
- Experience with photonic integrated circuit (PIC) fabrication.
- Familiarity with additional epitaxy techniques (e.g., MBE).
- Experience scaling processes from R&D to high-volume manufacturing.
Other Requirements
- Willingness to work in a cleanroom environment (full PPE required).
- Eligible to work in the UK.
- Standard working hours (9am–5pm), with flexibility for overtime and occasional shift work as required.
