11.24 EM Vstress2[2]: Electromigration test, voltage stressed, 2 SMUs (A.03.10)
[Supported Analyzer]
B1500A
[Description]
Performs the Electromigration (EM) test, and plots the stress time vs resistance characteristics. This test is
performed by the sampling measurement mode as shown below.
1. applies stress voltage
2. performs measurement and saves measurement data
3. calculates the device failure time
