Method for producing semiconductor films

摘要

A method for producing semiconducting films on a substrate wherein a plasma of a reactive gas is generated and an ion beam from the plasma is directed and accelerated toward a target of material of which the film is to be formed. The target which is maintained in a vacuum chamber at reduced pressure, is sputtered with the reactive ion beam and the material sputtered off the target is collected as a film on a substrate which is physically isolated from the plasma generating process and the sputtering process. Preferably the reactive gas is present in a mixture with an inert gas heavier than the reactive gas.
