For the GaN current collapse measurement, HVSMU applies high voltage stress to
the device under test (DUT) when it is in the OFF state. After that, HVSMU
performs voltage measurement and HCSMU performs I-V measurement to monitor
the ON state characteristics which is given by the voltage measured by HVSMU and
the total current measured by HCSMU and HVSMU.
Source setting values available for HVSMU and HCSMU are shown in
and 3-9. And measurement ranges are shown in
