The pulsed IV test system supports the measurement of the three-terminal MOSFET
(source and well (substrate) are shorted). And its measurement path must be
extended to the RF probes as shown in
Figure 2-1 to achieve 10 ns minimum pulse
width. One measurement path is for the gate terminal and the other path is for the
drain terminal. Moreover the source/well terminal must be electrically connected to
the ground via the shielding of the measurement path (RF probes and measurement
cables). See
Figure 2-2 .
Figure 2-1 RF Probe Connection
Prepare two RF probes to perform the pulsed IV measurement. The RF probe must
have the signal line and the ground lines as shown in
Figure 2-2 . The signal line is to
contact the gate or drain pad, and the ground lines are to contact the source/well
pads. For the RF probe and its installation, consult your favorite prober vender.
