Abstract

A composite flip chip semiconductor device (10) permits burn-in testing and rework to be performed on the device while also enhancing electrical, thermal, and mechanical device performance. The device includes a semiconductor die (12) having a plurality of bonding pads (14). Also included in the composite device is an interposer (22) having a first surface with a plurality of traces (26). A plurality of vias (24) extend from the first surface of the interposer (22) to a second surface. The semiconductor die (12) is electrically coupled to the plurality of vias of the interposer which in turn is to be coupled to a substrate.
