Key Responsibilities

  • Lead and manage SiC crystal growth projects, including planning, execution, and reporting.
  • Develop and optimize crystal growth technologies for semi-insulating SiC wafers using Physical Vapor Transport (PVT).
  • Design, execute, and analyze SiC crystal growth experiments using PVT and related techniques.
  • Develop physics-based, data-driven, and digital twin models to enhance 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 regarding resistivity, defect density, crystal quality, and uniformity.
  • Collaborate with device, epitaxy, and integration teams to ensure material performance meets device requirements.
  • Troubleshoot processes and equipment, preparing technical documentation such as SOPs, OCAPs, FMEA, and SPC.
  • Guide equipment engineers in maintaining PVT and supporting tools to achieve high uptime.

Requirements

  • PhD in Materials Science, Electrical Engineering, Physics, or a related discipline.
  • 3 - 5 years of hands-on experience in 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 capable of working independently and collaboratively in a team environment.
