Abstract
A method of making inclined sides on a metal pattern which is grown on a substrate by electroplating as a preliminary measure to the coating of the substrate with the metal pattern by an insulating layer. The main deposition of the insulating layer by sputtering is preceded by a sputter-etching step which transforms the rounded edges of the metal pattern into inclined sides.
