Abstract

Abstract Two superimposed series of electric contacts (3, 4) in the shape of metal-sheet strips, electrically connected to a metallic place (2) which supports a semiconductor chip (5), are electrically separated but mechanically connected by an interposed layer of adhesive material (8) at high insulation. The whole is completely inserted in a covering (14) of insulating material, which forms a flat support, from which, at opposite faces, only limited adjacent contact portions (9,10) of said electric contacts emerge. The place (2) and at least one of the two series of contacts (3,4) make part of a single starting metallic frame (1) on which the other series of contacts is superimposed. This latter in its turn can make part of the same metallic frame (1) and to be superimposed by refolding or can be prepared separately and then applied on the first series.
