Government. Test shall be performed on each sublot.
Electrical
During the PRM test, the voltage (VBR) shall be monitored
measurement
to verify it has not collapsed. Any collapse in VBR during
or after the PRM test, or rise in leakage current (IR) after
the test that exceeds IR1 in table I, shall be considered a
failure to that level of applied PRM. Progressively higher
levels of PRM shall be applied until failure occurs on all
devices within the chosen sample size to characterize
each sublot.
