Table 2-4 Connection to the DUT Interface
CAUTION Never connect the guard terminal to any output, including circuit common, chassis
ground, or the guard terminal of any other unit. Doing so may result in an
emergency condition.
For highly accurate current forcing and measurements while minimizing leakage,
surround all force and sense lines from SMU by a guard as far as possible, and make
cables stable by taping.
For reducing capacitance measurement error, tape the cables to any grounded
materials such as shielding box. If you use probe card, grounding the probe card also
reduces capacitance measurement error.
Kelvin connections non-Kelvin connections
This connection is available only for the
Kelvin connectors.
This connection can cancel effects of cable
resistance by connect sense line and force line
as close as possible to DUT terminal.
Following connection is for the Kelvin
connectors. For the triaxial connectors,
ignore SENSE terminal, and make
connection only for FORCE terminal.
Measurement data will include residual
resistance from the connection cable.
