摘要

本文给出了一种预估CMOS器件辐照感生漏电流的总剂量辐射响应模型

并利用模型计算了非加固C4007B和加固CC4007RHNMOS器件受不同γ射线剂量率辐射下的总剂量效应。研究结果表明

在实验室选用任意一特定剂量率进行辐射实验和室温退火

利用给定的模型可以预估其它剂量率辐射下的总剂量效应

并给出了CC4007RH和C4007B器件空间低剂量率（1×10-4-1×10-2rad/s）环境下的漏电流的预估结果。

Abstract

A radiation response model of total dose effect for CMOS devices in a space environment is presented to predict the radiation-induced leakage current. Total effects for CC4007RH and C4007B devices at different dose rates irradiation of γ rays were calculated by using the established model. So long as total dose irradiation test and post-irradiation annealing test at room temperature were carried out by choosing one dose rate at random

total dose irradiation effects at other dose rates can be predicted by using the established models. Finally

the prediction results of 10-4-10-2 rad·s-1 low dose rate irradiation for CC4007RH and C4007B devices in space environment were presented.
