Research on laser radiation for simulating dose rate effects in semiconductor materials

In this paper, a laser radiation model based on TCAD is built up. With this model, some simulations of laser irradiating semiconductor material are presented. And also simulations of gamma ray irradiating semiconductor material are given. By comparing the simulation results the relationship between laser intensity and gamma dose rate is obtained. The results demonstrate that the laser radiation model is practicable in TCAD for reliability analysis and the laser simulation technique is reliable to simulate dose rate effect.
