Abstract:
1. A method for connecting a first integrated circuit and a second integrated circuit, the method comprising: providing a plurality of first integrated circuits, each of which includes a first wiring device on a first main surface, and a corresponding plurality of second integrated circuits, each of which includes a second wiring device on a second main surface, the plurality of first integrated circuits and the plurality of second integrated circuits being in the form of chip pairs; wherein one of the first and second wiring devices comprises a plurality of elevated contact areas lying on respective elastic elevations and wherein the other of the first and second wiring devices comprises a plurality of non-elevated contact areas that can be aligned to the elevated contact areas; mounting the first integrated circuits onto a substrate; dispensing a liquid adhesive on at least one of the first and second main surfaces; aligning the first and second main areas so that the elevated contact area and the corresponding non-elevated contact area are brought into electrical contact; pressing said first and second main areas by simultaneously applying pressure onto the plurality of second integrated circuits using a pressure plate, such that the elevated contact areas are deformed; and curing the adhesive, thereby firmly connecting the first and second integrated circuits, wherein curing the adhesive includes at least partially curing the adhesive while the elevated contact area is deformed such that the elevated contact area remains deformed subsequent to connecting the first and second integrated circuits.
