[Description]
Performs the TDDB (time dependent dielectric breakdown) test, and plots the stress time vs voltage
characteristics. This test is performed by the sampling measurement mode.
[Device Under Test]
MOS capacitor, insulator, oxide layer, and so on
[Device Parameters]
Polarity: Nch (SMUs force the specified value) or Pch (SMUs force the negative specified value).
L: Port1 terminal length
W: Port1 terminal width
Temp: Temperature
[Test Parameters]
Port1: SMU connected to Port1 terminal
Port2: SMU connected to Port2 terminal
TotalStressTime: Total stress time. 10 to 10000 seconds.
I1Stress: Port1 stress current
V1Limit: Port1 voltage compliance
I2Limit: Port2 current compliance
IntegTime: Integration time
PointPerDecade: Number of samples in 1 decade
Interval: Sampling interval
FailureCondition: Measurement stop condition
[Extended Test Parameters]
V2: Port2 terminal voltage
HoldTime: Hold time
Port2MinRng: Minimum range for the port2 current measurement
StoringRuntimeData: Data save during stress output, Yes or No
