Device for the condensation deposition of a film on a substrate

摘要

A device for forming a coating on a substrate (8) by condensation of an element, notably a metal, incorporates a conducting wall (9, 9a, 9b) delimiting at least laterally the space (2') between the target (7) and the substrate (8) with provision for negative or positive polarization of this wall (9, 9a, 9b) with respect to the substrate (8). The device comprises:- a) an enclosure (2) in which is a target (7) presenting at least a surface layer of the material to be condensed onto the substrate; b) some means (1) for evaporating this material; and/or c) some means for producing the cathodic pulverization of this material from the target (7) to the substrate (8).
