Abstract:
The invention relates to a flip-chip module with a semiconductor chip with contact posts, wherein the contact posts are connected electrically and mechanically to a substrate. Provided between the substrate and the semiconductor chip is a spacer, which is coupled mechanically to the substrate and/or the semiconductor chip. By this means, thermal stresses in the flip-chip module are absorbed by the spacer and kept away from the semiconductor chip.The invention also relates to a method for the production of a flip-chip module, in which firstly a spacer is located between the semiconductor chip and the substrate, after which the contact posts are soldered to the contact points of the substrate. Through the provision of the spacer the distance between the semiconductor chip and the substrate is set precisely, thereby improving the quality of the soldering points.
