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

Claim 16:
17. A method comprising:
forming a first semiconductor device comprising:
directly bonding a first die to a second die, wherein the first die comprises conductive features protruding from a side opposite the second die;
depositing a first dielectric layer on a surface of the second die, sidewalls of the first die, and over the conductive features;
depositing a second dielectric layer on the first dielectric layer; and
performing a planarization process to expose the conductive features and the first dielectric layer;

surrounding the first semiconductor device with a molding material;
forming a through-via penetrating through the molding material;
forming a redistribution structure on the molding material, the first semiconductor device, and a first side of the through via, wherein the redistribution structure is electrically coupled to the first semiconductor device and the through via; and
bonding a second semiconductor device to the second side of the through via.
