Epitaxy Process Engineer

Job Summary

We are seeking a highly motivated and experienced Process Engineer (Senior) with strong expertise in III-V Epitaxy to drive the development and manufacturing of high performance semiconductor devices (such as lasers for AI data centers). The role centers on III-V epitaxial growth process development (MOCVD) combined with wafer fabrication, supporting both R&D and high-volume production. The candidate will play a key role in process optimization, yield improvement, and new product introduction (NPI).

Key Responsibilities

• Lead the development, optimization, and qualificationof III-V epitaxial growth processes (primarily MOCVD) for various device structures to meet R&D and production requirements.
• Drive continuous improvement of process quality such as: uniformity, defect density, and reproducibility.
• Support New Product Introduction (NPI) from design structure to manufacturable process flow.
• Collaborate closely with international teams on process development, troubleshooting, and technology transfer.
• Utilize data analytics, AI/ML tools, and statistical process control to enhance process capability and manufacturing efficiency.
• Perform and support advanced characterization and failure analysis.

Qualifications

Education

• Master’s or PhD degree in Physics, Materials Science, Electrical Engineering, Chemical Engineering, or a related semiconductor field is preferred.
• Bachelor’s degree holders with strong relevant industry experience are also encouraged to apply.

Experience & Technical Skills

• Hands-on experience in III-V epitaxial growth (MOCVD preferred) is preferred. Candidates with proven track record in developing and qualifying III-V epi processes for lasers, photodetectors, or other optoelectronic devices will be given priority.
• Deep understanding of epitaxial growth mechanisms, precursor chemistry, reactor dynamics, and structure design for III-V materials (e.g., GaAs, InP, GaN, or related compounds).
• Knowledge of semiconductor materials and device physics, especially for Laser applications.
• Familiarity with advanced materials characterization tools is an advantage: SIMS, XRD, AFM, SEM, Photoluminescence, Hall measurement, etc.
• Experience using data analytics, statistical process control (SPC), and AI/ML tools for epitaxial process optimization and controlis highly desirable

Exception

• Fresh graduates with a relevant Master’s or PhD degree are encouraged to apply. We provide comprehensive training from the fundamentals to help you succeed in the role. Candidates should possess a solid understanding of semiconductor materials and device physics.
