Making high voltage C-V measurements
The bias tees can hold charge and it is necessary to discharge them before opening the
cover of the Model 8010 and making changes to the cable connectors. See
Discharge bias
tee and system capacitance
(on page 3-28) later in this section.
When measuring capacitance through the Model 8010, disconnect the SMU Sense HI and
Sense LO cables at the device connections panel of the Model 8010.
Overview
Model 8010 capacitance-voltage (C-V) measurements use two or three bias tees to couple the DC
bias from a SMU instrument with the AC signal from an impedance measurement instrument. These
bias tees can enable C-V measurements with DC bias up to 3000 V and AC measurement
frequencies up to 1 MHz. Connections are supported to the following bias tee kits:
•
CVU-200-KIT
The kit includes three 200 V bias tees, cables, and connectors. It supports C-V measurements
with DC bias at up to three device terminals up to 200 V (refer to the CVU-200-KIT instructions;
document number 071321200).
