【Abstract】 A new method for rapid evaluation of reliablility of GaAs FET is proposed.Basing on the temperature characteristics of GaAs FET’s sensitive parameters for failure and its degrading characteristics under certain electrical stress,the relationship between the temperature and the degradation of sensitive parameters is extracted from the line through the method of temperature slope,then the related reliabilty physics parameters such as activating energy to failure can be figured out.
