| 20120015505 | METHOD AND DEVICE FOR PREPARING COMPOUND SEMICONDUCTOR FILM - The present invention discloses a method and a device for preparing a compound semiconductor film. The method comprises the steps of: providing a substrate above at least an evaporation source in a vacuum condition; heating a source material contained in the evaporation source so that the source material is vapor-deposited on the substrate; and taking out the substrate under protection of an inert gas. The substrate may be rotated around an axis of a plane where the evaporation source is positioned, and the substrate is tilted by a predetermined angle with respect to the plane. The compound semi-conductive film thus prepared has a uniform thickness with a larger area. The method provides a simplified process and enhanced efficiency. | 01-19-2012 |
