Abstract

The switching elements are formed in, or on, the semiconductor substrate and are connected with outside connecting leads. Each connecting point (322, 320) is coated with a protective layer of silicon dioxide (340), covering the connecting point and the directly adjacent part of the respective lead (331, 332). The protective coating is covered or enclosed by a plastics layer (360). Preferably the leads are of aluminium and the connecting points of aluminium pads. The integrated circuit elements may be coated by a doped silicon dioxide passivating layer not converting the connecting points. The silicon dioxide protective layer (340) may be undoped and may cover the entire passivating layer.
