Fast reliability testing is a key point for III-V technologies. This is particularly true when modifications have to be implemented on the production line. Such modifications can be sorted in four categories: raw material, new equipment, process step and design rule modifications. endurance tests have to be performed to ensure that through the modified steps the reliability of the technology has not been changed.
