Abstract:
1. A semiconductor component, comprising: a semiconductor chip having a first side and a second side, the second side having contact areas thereon; a chip island having the first side of the semiconductor chip mounted hereon; a flat conductor including inner and outer portions, the inner portions having contacts; bonding wires electrically connecting the contact areas on the second side of the semiconductor chip to the contacts of the flat conductor; a first part including a thermoset material embedding the semiconductor chip, the chip island, the bonding wires, and the inner portion of the flat conductor to form a semiconductor component casing; a second part including a thermoplastic material embedding the first part to form a casing retainer on the semiconductor component casing; and a porous adhesion-promoter layer located between the first and second parts, wherein the first part is bonded by the adhesion-promoter layer to the second part, and wherein the adhesion-promoter layer includes at least one of pyrolytically deposited semiconductor oxides and/or pyrolytically deposited metal oxides such that a first portion of the adhesion-promoter layer covers the first part with a pore-free fully compact morphology and the porosity of the adhesion-promoter layer gradually increases such that a second portion of the adhesion-promoter layer adjacent the second part has microporous morphology, and wherein the average thickness D of the adhesion-promoter layer is in the range 5 nm≦D≦40 nm.
