Abstract: Semiconductor devices having a conductive lead pattern on the bottom of the device are bonded to conductive pads on a substrate to form an electrical connection therewith. The connection comprises two layers of conductive adhesive plastic separated by a small chip of conductive alloy which melts above the curing temperature of the adhesive plastic. The non-destructive removal of a semiconductor device from the substrate is accomplished by heating only the semiconductor device to be removed until the alloy chip under the device melts, thus, permitting the non-destructive removal of the semiconductor device without the application of force which would tend to destroy the semiconductor device.
