Embodiment Construction

[0044] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0045] In this embodiment, the dielectric deposition, sputtering, sintering and other processes of the gallium arsenide production line are key processes, which directly affect the final product quality, and the final consistency of product quality is guaranteed through the prediction and feedback control of key processes. The process parameters of dielectric deposition are: temperature, pressure, gas flow, power. The process parameters of the sputtering process are: material purity, ion bombardment power, sputtering time, working pressure, and its quality characteristic parameter is the coating thickness; the process parameters of the sintering p...

Abstract

A method for controlling quality consistency of a gallium arsenide product comprises the following steps of 1, arranging historical process data for forming an original model sample database; 2, performing mathematical modeling on the process data in a production process by means of an artificial neural network; and 3, performing product quality forecasting, namely performing final product qualityforecasting by means of a mathematical model through the process data of the step, and after product finishing, comparing actual data of the product with forecast result data, thereby generating a product quality model report.

Description

technical field [0001] The invention relates to the technical field of product quality control, in particular to a method and system for controlling the quality consistency of gallium arsenide products. Background technique [0002] The production of gallium arsenide microwave devices and integrated circuits has the characteristics of complex process, multi-variety and small batch production, high consistency requirements, short product delivery period and high quality level requirements. The final management of product quality at the production site of gallium arsenide microwave devices is based on the "total quality management" method. [0003] In 1961, Feigenbaum of General Electric Company of the United States published the book "Total Quality Management", emphasizing that the implementation of quality functions is the responsibility of all personnel in the company, and all personnel should have the concept of quality and assume the responsibility for quality. After man...
