Key Responsibilities

  • Lead and manage SiC crystal growth-related projects, including planning, execution, and reporting
  • Develop and optimize crystal growth technologies for semi-insulating silicon carbide (SiC) wafers used as substrates for RF and millimeter-wave GaN devices
  • Design, execute, and analyze SiC crystal growth experiments using physical vapor transport (PVT) and related growth techniques
  • Develop physics-based, data-driven, and digital twin models to improve growth rate, resistivity control, and wafer uniformity
  • Apply AI/ML methods and materials simulations to optimize crystal growth processes and predict material properties
  • Characterize SiC crystals and wafers, including resistivity, defect density, crystal quality, and uniformity
  • Collaborate closely with device, epitaxy, and integration teams to ensure material performance meets device requirements
  • Troubleshoot processes and equipment to maintain tool performance and process quality using SOPs, OCAPs, FMEA, and SPC
  • Guide equipment engineers in maintaining PVT and supporting tools to achieve tool uptime above 90%
  • Document experimental results, prepare technical reports, and contribute to publications, patents, and project reviews

Requirements

  • PhD in Materials Science, Electrical Engineering, Physics, or a related discipline
  • 3 - 5 years of hands-on experience in silicon carbide (SiC) crystal growth using the Physical Vapor Transport (PVT) method
  • Experience with chamber-scale simulations for Physical Vapor Transport (PVT) processes
  • Strong background in SiC materials science and characterization of SiC wafers
  • Excellent communication skills, strong industry awareness, and proven problem-solving abilities
  • Highly motivated self-starter with the ability to work independently and collaboratively in a team environment
  • Prior industry experience is an advantage
