Abstract:
1. A method for the passivation of a semiconductor substrate, wherein a SiN x :H layer is deposited on a surface of the substrate by a PECVD process, comprising: placing the substrate in a processing chamber which has specific internal processing chamber dimensions, such as at least one internal length, width, height and/or diameter; maintaining a pressure in the processing chamber at a relatively low value; maintaining the substrate at a specific treatment temperature; generating a plasma by at least one plasma cascade source mounted on the processing chamber at a specific distance from the substrate surface, wherein at least a part of the plasma generated by the at least one plasma cascade source is brought into contact with the substrate surface; and supplying a flow of silane and a flow of ammonia to said at least part of the plasma.
