sponsor LogoIf you’ve worked with semiconductor devices like MOSFETs and diodes before, then you may be familiar with characteristic curves for those devices. But how do we actually obtain these curves and why are they so important? In this webinar, we’ll introduce what I-V characterization is, what instruments to use and demonstrate real-world examples of tests. You’ll leave with a foundational knowledge of basic characterization and an idea of how to scale up to more complex tests in the future.

Some of the topics we'll explore are what you'll need from your instrument when doing IV characterization, considerations for terminal devices,  and pro-tips for IV Characterizations.   There will also be a demo followed by a Q&A session.   

What You Will Learn By Attending:

  • What is IV Characterization?
  • What do you need from your instrument when doing IV Characterization?
    • Power supply + DMM
    • Why is an SMU better
      • Sourcing current/voltage + measuring
      • Current resolution
  • Considerations for 2 terminal devices
    • Diode
    • What kinds of test (vfd, vrd)
  • Considerations for 3 or 4 terminal devices
    • MOSFET
    • What kinds tests (vds-id, vgs-id, ig-vg)
    • Synchronizing steps and sweeps
    • Making multichannel synchronization easy with Kickstart or 4200A
  • Pro-tips for I-V Characterization
    • Mixing up terminals
      • Get a labeled test fixture or use switching if you’re changing configurations a lot
    • Self-heating
      • Use pulsed measurements
