Title: Method for judgment of good or bad of hetero junction bipolar transistor
Inventor: SUGAWARA HIROHIKO
IPC: G01R31/302
Filed: 1994-05-20
Abstract: PURPOSE:To reduce an inspection time by a method wherein it is judged whether a grounded emitter current gain measured under a predetermined second measurement condition after operating during a second inspection time period that is sufficiently smaller than a first inspection time period becomes a predetermined value or greater by increasing from an initial value at a time when the second inspection time period is 0. CONSTITUTION:As a first inspection condition of a manufactured hetero junction bipolar transistor, it is operated for the inspection during a comparatively long time, e.g. 1000 hours, in conditions of a prescribed high junction temperature, a prescribed high collector-emitter voltage and a high density of a collector current. As a second inspection condition, it is operated in conditions of a prescribed low junction temperature, a prescribed low collector-emitter voltage and a low base-emitter voltage so that a base current is measured. A grounded emitter current gain beta and an increasing rate DELTAbeta with respect to an initial gain beta0 of the transistor that is manufactured such that the base current is increased to a predetermined value, i.e., ten times of the initial value or greater, are obtained. The good or bad is judged based on whether a variation rate DELTAbeta/beta of the grounded emitter current gain beta is the predetermined value or greater that is increased comparatively a bit from the initial valve beta0.
