The purpose of High Temperature Gate Bias is to stress the devices with the
applied bias to the gate while at elevated junction temperature to accelerate time
dependent dielectric breakdown of the gate structure.
D
The primary failure modes for long term gate stress is a rupture of the gate oxide,
causing either a resistive short between gate-to-emitter or gate-to-collector or what
appears to be a low breakdown diode between the gate and source.
The oxide breakdown has been attributed to the degradation in time of existing
defects in the thermally grown oxide. These defects can take form of localized

As with HTRB, extreme care must be exercised in the course of a long term test to
avoid potential hazards such as electrostatic discharge or electrical overstress to
the gate during test. Failures arising from this abuse are virtually indistinguishable
from true oxide breakdown which result from the actual stress test.
