TCAD Simulation of Wide Bandgap Power Devices

Simulation of wide bandgap power devices has always posed convergence challenges. In addition to this the emphasis is shifting to accuracy and calibration of models relative to manufacturing data. This webinar will focus on simulation of silicon carbide (SiC), gallium nitride (GaN) and gallium oxide (Ga2O3) power devices. For each case, simulation results and calibration techniques will be described. Finally, we will also cover stress simulations and introduce upcoming process simulation capabilities for wide bandgap materials.

What attendees will learn:

  • 4H-SiC IEMOSFETsimulation
    • Specify the interface defects Dit
    • A mobility model including the remote-scattering effect due to interface charges
  • GaN Super HFETsimulation
    • Polarization charges: 2DHG, 2DEG at the double-hetero interface GaN/AlGaN/GaN
    • Specification of defects in the GaN buffer layer
    • Breakdown simulation
  • Ga2O3 simulation
    • Affinity, bandgap (4.8eV)、effective density of state (electron and hole)
    • How to deal with convergence problems
  • Stress simulation of wide bandgap devices
  • Upcoming wide bandgap process simulation capabilities
