Patent ID: 11955433
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method, comprising:
bonding a first semiconductor device to a top surface of a wafer using a direct bonding process, wherein the first semiconductor device is electrically connected to the wafer after bonding, and wherein the first semiconductor device comprises first through substrate vias;
exposing the first through substrate vias by removing a portion of the first semiconductor device;
depositing a dielectric material over the first semiconductor device and the wafer;
bonding a second semiconductor device to a top surface of the first semiconductor device using a direct bonding process, wherein the second semiconductor device is electrically connected to the first semiconductor device after bonding;
singulating the wafer to form a die package;
attaching the die package and a third semiconductor device to a carrier;
forming first through vias on the carrier;
encapsulating the die package, the third semiconductor device, and the first through vias with an encapsulant;
thinning the encapsulant to expose the through substrate vias; and
forming a first redistribution structure over the encapsulant, wherein the first redistribution structure is electrically connected to the through substrate vias, the third semiconductor device, and the first through vias.
