TCAD-based Model Extraction Flow for GaN HEMT Devices – Part 2

This webinar represents a continuation of a previously presented parameter extraction methodology for GaN HEMT devices. This will include generating I-V and C-V data through TCAD device simulations. Asymmetric vs. symmetric device structures are considered. The extraction of SPICE model I-V and capacitance parameters will be illustrated in detail, with emphasis on asymmetric devices.

What attendees will learn:

  • Asymmetric vs. symmetric device GaN HEMT structures
  • Generating I-V and capacitance data using TCAD device simulation
  • I-V and C-V data conversion for parameter extraction
  • Extraction of SPICE model parameters for GaN HEMT devices
    • Parameter extraction of asymmetric devices
    • I-V modeling
    • Capacitance modeling
    • Flow description
    • Running the flow and illustrating the results
