Abstract

The present invention includes analysing gallium arsenide monolithic microwave integrated circuit, thereby obtaining chip concerned rate of failures and package and external environment concerned rate of failures; according to chip concerned rate of failures and package and external environment concerned rate of failures sum to evaluate gallium arsenide monolithic microwave integrated circuit degree of reliability. The present invention provides guideline for gallium arsenide monolithic microwave integrated circuit rate of failures level and reliability evaluating.

Description

technical field [0001] The invention relates to gallium arsenide monolithic microwave integrated circuit technology, in particular to a method for evaluating the reliability of gallium arsenide monolithic microwave integrated circuits based on mathematical statistics and failure physics. Background technique [0002] Monolithic Microwave Integrated Circuits (MMIC) are passive and active components prepared on a semi-insulating semiconductor substrate by epitaxy, implantation, photolithography, evaporation, sputtering, etc., and connected to form a microwave (even Millimeter wave) frequency band functional circuit. It includes all monolithic integrated circuit chips and their packages that can realize digital and analog functions in the range of 1-300GHz, and its frequency range can even be extended to the entire radio frequency range. Due to the high electron mobility, wide band gap, wide operating temperature range, and good microwave transmission performance of gallium ar...
