Abstract:
1. A method of manufacturing an electronic device, a semiconductor device in particular but not exclusively, which method comprises the steps of: applying a semiconductor substrate which is provided with a conductor at a surface, the conductor having a top surface portion and sidewall portions, of which at least the top surface portion is provided with an etch stop layer comprising silicon carbide; applying a dielectric layer, etching a via in the dielectric layer over the conductor, and stopping on the etch stop layer to create an exposed part of the etch stop layer; removing the exposed part of the etch stop layer inside the via from at least the top surface portion of the conductor; and filling the via with a conductive material; wherein the etch stop layer is applied to the top surface portion and the sidewall portions of the conductor after the provision of the conductor at the surface of the semiconductor substrate.
