Abstract :
Accelerated lifetime tests have been performed on integrated planar GaAs Schottky diodes that were bonded to quartz substrates upside-down with a heat-cured epoxy. Results at 175°C, 200°C, and 240°C were analyzed using the Arrhenius-lognormal model. These tests predict a room temperature MTTF of 3×108 hours, a value that is comparable to conventional high-frequency planar Schottky diodes. This result demonstrates that the use of an appropriate epoxy to obtain GaAs devices on quartz substrates does not significantly reduce the lifetime of the devices
