Senior Epi & Fab Process Engineer

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 qualification of 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 control is highly desirable • Fresh graduates with a 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.
