Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A semiconductor structure comprising:
a bottom die;
a top die, wherein a backside of the top die is attached to a front side of the bottom die;
a first conductive pillar attached to the front side of the bottom die adjacent to the top die;
a dielectric material on the front side of the bottom die and around the top die and the first conductive pillar, wherein the first conductive pillar extends through the dielectric material;
a molding material around the top die, the bottom die, and the first conductive pillar;
a second conductive pillar in the molding material, wherein the second conductive pillar extends through the molding material; and
a redistribution structure on the molding material and electrically coupled to the top die, the first conductive pillar and the second conductive pillar, wherein the top die is between the bottom die and the redistribution structure.
