Patent ID: 7670876

Claim:
A method for manufacturing an integrated circuit device comprising the steps of: providing at least a dummy chip having a chip-mounting surface, the dummy chip including at least an embedded component, a plurality of redistribution traces formed on the chip-mounting surface and a plurality of flip-chip pads formed on the chip-mounting surface, the embedded component being electrically connected to one of the flip-chip pads via one of the redistribution traces, wherein the dummy chip has a passivation layer formed on the chip-mounting surface and covering the redistribution traces and the embedded component; providing at least a flip chip having an active surface, a back surface and a plurality of bonding pads formed on the active surface; mounting the flip chip on the chip-mounting surface of the dummy chip via a plurality of bumps, the bumps electrically connecting the bonding pads of the flip chip with the flip-chip pads of the dummy chip.
