Patent ID: 11923352
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 17:
18. A method for manufacturing a semiconductor device, comprising:
forming a first semiconductor die comprising a first deep trench capacitor (DTC) and a second deep trench capacitor;
forming a second semiconductor die comprising a processing unit;
stacking the first semiconductor die on the second semiconductor die along a first direction; and
electrically connecting the first deep trench capacitor to a power line configured to provide a power signal to the processing unit, wherein the second deep trench capacitor is spaced apart from the first deep trench capacitor along a second direction vertical to the first direction, and a distance between the first deep trench capacitor and the second deep trench capacitor is smaller than a depth of the first deep trench capacitor.
