Abstract
Abstract An integrated circuit arrangement comprises a semiconductor body carrying an integrated circuit which is embedded in an insulating material casing together with a plurality of flat strip lines for making electrical connection with the semiconductor body, and a layer of electrically conductive material in or on the casing in a plane substantially parallel to the flat strip lines only on the side of the semiconductor body in which the construction elements forming the integrated circuit are located.
