Patent ID: 8728929

Claim:
A method of manufacturing a semiconductor device, the method comprising: providing a substrate carrier having a front side and a backside opposite to the front side (S 1 ), the substrate carrier comprising a substrate layer and a patterned conductive layer at the front side (S 1 ) of the substrate carrier, wherein the patterned conductive layer defines contact pads to be formed for being connected to terminals of a semiconductor chip; partially etching the substrate carrier using the patterned conductive layer as a mask to obtain trenches in the substrate carrier and defining contact regions in the substrate layer; providing the semiconductor chip comprising the terminals at a first side (S 1 ) and an adhesive layer at a second side opposite to the first side (S 1 ); mounting said semiconductor chip with the adhesive layer on the patterned conductive layer such that the semiconductor chip covers at least one of the trenches and part of the contact pads neighboring the respective trench are left uncovered for future wire bonding; providing wire bonds between respective terminals of the semiconductor chip and respective contact pads of the substrate carrier; providing a molding compound covering the substrate carrier and the semiconductor chip and filling the trenches, and etching the backside (S 2 ) of the substrate carrier, preferably selective to the substrate layer, to expose the molding compound in the trenches for separating the contact regions at the backside (S 2 ) of the substrate layer that are in electrical contact with the respective contact pads wherein, during the etching of the backside (S 2 ) of the substrate carrier the substrate layer is completely removed from the entire patterned conductive layer such that the contact regions are located directly on a backside (S 2 ) of the contact pads.
