Patent ID: 8541786

Claim:
A method of manufacturing a semiconductor device including a semiconductor chip, the method comprising: providing a substrate having a first side and a second side opposite to the first side; providing a photoresist layer on the first side of the substrate, the photoresist layer including an opening extending to the substrate and having pre-shaped sidewalls; filling the opening with an electrically conductive material for defining a contact pad to be formed for being connected to a terminal of a semiconductor chip, wherein the contact pad has further sidewalls that correspond to the pre-shaped sidewalls of the photoresist layer, wherein the sidewalls of the photoresist layer are pre-shaped such that the further sidewalls contained within the opening are formed with a protrusion in a direction having a component orthogonal to the respective sidewall; removing the photoresist layer; providing the semiconductor chip and mounting said semiconductor chip on the first side of the substrate such that one terminal is electrically connected to the contact pad; and providing a protective compound covering the substrate and the semiconductor chip and at least the protrusion of at least one of the further sidewalls of the contact pad, the further sidewalls and the protective compound being configured and arranged to secure the semiconductor chip to the contact pad.
