Abstract:
1. A method comprising: placing a conductive adhesive on at least one of a first wafer and a second wafer, the first wafer having first and second surfaces and semiconductor devices, the first wafer including bond pads located on the first surface and coupled to respective semiconductor devices, the second wafer having an electrical component; forming conductive balls on the bond pads on the first surface of the first wafer; and causing the conductive balls to adhere to the bond pad and the conductive adhesive to adhere the first wafer to the second wafer by heating the conductive balls and the conductive adhesive, wherein the heating that causes the conductive balls to adhere to the bond pad is performed concurrently with the heating that causes the conductive adhesive to adhere the first wafer to the second wafer.
