ABSTRACT:
A flip-chip semiconductor device comprises a carrier substrate having a conductor pattern on at least one side, and at least one semiconductor die with an active surface and an opposed ground surface. A conductive backing plate is conductively bonded to the ground surface. The active surface faces and is electrically connected to the conductor pattern of the carrier substrate. A conductive down-bond connection is provided between the backing plate and a ground connection or reference potential connection. The backing plate is preferably rigid and can be manipulated for indirect alignment of the die or dice carried thereon relative to the substrate.
