ABSTRACT:
A method for testing a batch of semiconductor devices in wafer level is provided. The method includes the following steps: (a) obtaining a breakdown voltage of gate dielectric of each semiconductor device; (b) applying, to the gate dielectric of each semiconductor device, a stress voltage below the breakdown voltage but above a base voltage of gate dielectric of the semiconductor devices; (c) after the step (b), measuring currents of gate dielectric of each semiconductor devices at the base voltage; and (d) obtaining a tailing distribution from the measured currents.
