Abstract:
1. An electronic element incorporating a composite dielectric region (CDR) under a bonding pad coupled to an active device, comprising: a semiconductor (SC) substrate having a first thermal expansion coefficient (TEC) and an active device region and a bonding pad region; a dielectric region located in the bonding pad region and comprising an insulating material having a second TEC; inclusions of a further material within the dielectric region, the further material having a third TEC less than the second TEC; further dielectric regions covering the inclusions; the bonding pad located in the bonding pad region and overlying the further dielectric regions, wherein the dielectric region and the further dielectric region electrically isolate the inclusions from the substrate and the bonding pad; and an active device located in the active device region and proximate the composite dielectric region, having a first terminal electrically coupled to the bonding pad by an interconnection.
