Abstract:
A method for manufacturing a semiconductor device that includes a semiconductor chip and a substrate, the substrate having a chip-mounting surface provided with a plurality of contact pads, the semiconductor chip having a pad-mounting surface provided with a plurality of bonding pads, which are to be connected to corresponding ones of the contact pads, said method comprising the steps of:forming a first conductive bump on each of the contact pads of the substrate; forming a second conductive bump on each of the bonding pads of the semiconductor chip; forming a plurality of spaced apart dielectric supporting pads on a selected one of the chip-mounting surface of the substrate and the pad-mounting surface of the semiconductor chip at positions offset from the first and second conductive bumps; mounting the semiconductor chip on the substrate to confine therebetween a gap and to permit each of the first conductive bumps to be vertically registered with and to contact a respective one of the second conductive bumps and to permit the supporting pads to interconnect the chip-mounting surface and the pad-mounting surface; reflowing the first and second conductive bumps in a manner that each of the first conductive bumps is bonded to the respective one of the second conductive bumps; and forming an insulating layer that fills in the gap and that encapsulates the supporting pads and the first and second conductive bumps.
