【Abstract】 The process characteristics of growth of semiconductor film are analyzed. Then,a set of real-time monitoring system of semiconductor film growth is designed for the ECR-MOCVD in our lab.The hardware and the realization of system software for real time monitor with VB6.0 based on WIN 98 are introduced. The practical application shows that the growth process can run continuously and stably in this real-time monitoring system. Meanwhile, the accuracy of the experiment parameters and the reproducibility of the growth process are improved significantly.更多还原
