Patent ID: 11862535
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An integrated chip, comprising:
a semiconductor device arranged along a first side of a semiconductor substrate, wherein the semiconductor substrate comprises one or more sidewalls extending from the first side of the semiconductor substrate to an opposing second side of the semiconductor substrate;
a dielectric liner lining the one or more sidewalls of the semiconductor substrate;
a through-substrate-via (TSV) arranged between the one or more sidewalls and separated from the semiconductor substrate by the dielectric liner; and
wherein the dielectric liner has sidewalls that slope inward towards one another from an upper surface of the dielectric liner arranged directly below the TSV to a topmost surface of the dielectric liner over the one or more sidewalls of the semiconductor substrate, so that the dielectric liner overhangs the TSV in a cross-sectional view.
