Assignee: ADEIA SEMICONDUCTOR BONDING TECHNOLOGIES INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A method of making a bonded image sensor device, comprising:
creating conductive through-vias in a carrier wafer;
conductively bonding a first element to first ends of the conductive through-vias in the carrier wafer, wherein the first element has a first footprint size;
conductively bonding a second element to second ends of the conductive through-vias of the carrier wafer, wherein the second element has a second footprint size different from the first footprint size; and
at least partly filling lateral spaces around the second element with an encapsulating material, wherein one of the first element or the second element is an image sensor and the other of the first element or the second element is an image processor;
planarizing a surface of the second element; and
planarizing a surface of the encapsulating material.
