Senior Staff MOCVD Development Engineer

The Senior Staff MOCVD Development Engineer will lead process and hardware development for GaN-based epitaxial growth on silicon and sapphire substrates enabling next-generation power devices. This role emphasizes deep technical understanding of MOCVD reactor behavior GaN heterostructure engineering and epitaxial integration for p-GaN and e-mode (enhancement-mode) device architectures. The ideal candidate combines strong experimental rigor demonstrated materials expertise and cross-functional leadership to translate research concepts into production-capable processes.

Responsibilities: 

• Develop optimize and transfer MOCVD epitaxial processes for GaN-on-Si and GaN-onSapphire wafers focusing on high-performance device layers targeting e-mode (p-GaN gate) and HEMT applications.
• Design and execute development roadmaps for buffer structure engineering strain management and defect reduction to achieve target breakdown voltages leakage and mobility metrics.
• Lead process integration studies addressing p-type activation Mg incorporation compensation control and interface optimization for gate reliability.
• Drive reactor-scale modeling and hardware tuning to improve growth uniformity thickness control and wafer bow mitigation on large-diameter substrates.
• Analyze defect physics mechanisms (threading dislocations V-defects point defects) affecting device reliability and performance driving iterative improvements in process conditions.
• Design and execute structured experiments (DOE-based) to deconvolve multi-parameter interactions in reactor conditions precursor chemistry and thermal profiles.
• Characterize epitaxial films using XRD AFM TEM PL CV and Hall measurements correlating data to growth parameters and device performance.
• Collaborate closely with device engineers and reliability teams to co-optimize epitaxial structures for threshold voltage dynamic Ron off-state leakage and long-term stability
• Translate device performance specifications and reliability requirements into detailed epitaxial process and material specifications; document Process of Record (PoR) and engineering specifications for qualification and manufacturing handoff.
• Support failure analysis root cause investigations and corrective action implementation for process-related device excursions or reliability issues.
• Lead process transfer activities from R&D to pilot or production-scale reactors ensuring knowledge capture and robust parameter windows

Qualifications :

• Education: Ph.D. in Materials Science Electrical Engineering Physics or closely related discipline. M.S. with 10 years of directly relevant hands-on experience.
• Minimum 8 years of direct hands-on MOCVD process development and optimization for III-V or III-nitride semiconductor materials (GaN AlGaN InGaN etc.).
• Demonstrated technical expertise in GaN-on-Si and/or GaN-on-Sapphire heterostructures including buffer layer design strain engineering and defect reduction strategies.
• Strong experience developing p-type GaN epitaxy and e-mode device architectures with deep understanding of Mg activation dopant diffusion control and gate stack engineering for threshold voltage stability.
• Proficiency with advanced epitaxial layer characterization techniques (XRD SIMS CL TEM PL Hall effect measurements) and ability to interpret results to guide process optimization.
• Track record of designing complex DOEs executing structured experiments conducting statistical analysis (SPC multivariate data interpretation) and drawing evidence-based conclusions. Demonstrated success in transferring epitaxial processes from R&D to pilot or high-volume manufacturing environments with understanding of manufacturability constraints and yield optimization.
•  Excellent written and verbal communication skills.
• Experience with multiple MOCVD platforms (e.g. Aixtron G5 G4 or Veeco Propel systems) - preferred
• Familiarity with GaN power device design requirements and performance metrics - preferred
• Prior leadership or mentoring experience in an R&D or manufacturing engineering environment -preferred
