Patent ID: 8502362

Claim:
A semiconductor package comprising: a lead; a silicon-on-insulator (SOI) die, the SOI die comprising an insulating layer sandwiched between a handle layer and an active layer, the handle layer having a first surface in contact with the insulating layer and a second surface opposite to the first surface, the SOI die being oriented in the package with the active layer facing the lead; and a metal bump connecting a contact pad at a surface of the active layer with the lead, the contact pad being formed in a thermal island in the active layer, the thermal island being defined by at least one dielectric filled trench, the trench extending between the surface of the active layer and the insulating layer and being laterally enclosed within the active layer, the SOI die, the metal bump and at least a portion of the lead being encased in a molding compound, the molding compound completely covering the second surface of the handle layer.
