Abstract:
1. A method of forming a bonded semiconductor structure circuit, comprising: providing a support substrate which carries a first semiconductor circuit; providing a first interconnect region carried by the support substrate, the first interconnect region including a conductive line connected to the first semiconductor circuit, wherein the conductive line includes a refractory metal; providing a first bonded semiconductor substrate which is bonded to the first interconnect region through a first bonding interface; forming a second semiconductor circuit which is carried by the first bonded semiconductor substrate; forming a dielectric layer which is adjacent to a first sidewall of the first bonded semiconductor substrate; forming a conductive line which extends through the dielectric layer; and providing a second interconnect region which is carried by the first bonded semiconductor substrate, wherein the second interconnect region is connected to the second semiconductor circuit; wherein the first and second semiconductor circuits are connected together through the first and second interconnect regions and the conductive line extending through the dielectric layer.
