11.27 HCI 3devices: Hot Carrier Injection test, 4 terminals, 3 devices (A.01.20)
[Supported Analyzer]
B1500A
[Description]
Performs the hot carrier injection test, and plots the accumulated stress time vs threshold voltage/drain current
characteristics. Maximum three devices can be measured by a test execution. This test is performed as follows.
1. performs initial characterization
2. applies stress voltage
3. performs interim characterization
4. saves measurement data
5. repeats 2 to 4 until TotalStressTime elapses
[Device Under Test]
MOSFET, 4 terminals, 3 devices
[Required Accessories]
Agilent B2200A or B2201A switching matrix 1 unit
GPIB cable
Connect B2200A/B2201A to B1500A with a measuring cable and GPIB cable.
Set information on B1500A SMU channel's connection to the B2200A/B2201A input port properly on the
Switching Matrix tab screen of the Configuration window.
Set the output channel number of B2200A/B2201A connected to each terminal of a device under test properly
in the Tr#Gate/Tr#Drain/Tr#Source/Tr#Subs field (# is an integer from 1 to 3) of Test Parameters area.
