Method for the production of semiconductor devices

摘要

A method for the production of semiconductor devices comprising introducing source gases, etching gases or source molecules into a substrate to grow crystalline layers on said substrate or to etch said substrate, resulting in a semiconductor device, wherein said method further comprises applying a given electric potential to said substrate; applying an electric potential that is different from that of said substrate to an electron-beam irradiator disposed directly above said substrate; and irradiating said irradiator with electron beams from an electron-beam emitting means, whereby said substrate is irradiated with the secondary electron beams generated from said irradiator and/or with the electron beams transmitted through said irradiator.
