Patent ID: 11862559
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A semiconductor structure, comprising:
a semiconductor substrate, wherein a fin element extends above the semiconductor substrate, wherein the fin element extends a first direction in a top view of the semiconductor substrate;
a gate structure extending over the fin element, the gate structure extending in a second direction in the top view, the second direction perpendicular to the first direction;
a source/drain region in the fin element;
a source/drain contact extending to the source/drain region;
a dielectric layer over the source/drain contact;
a first metallization feature over the dielectric layer, wherein the first metallization feature has a first shape defined in a cross-section along first direction, the first shape comprising:
a first bottom surface,
a first sidewall extending upward from a first end of the first bottom surface at a first acute angle;
a second sidewall extending upward from a second end of the first bottom surface at a second acute angle;
a second metallization feature over the dielectric layer and coplanar with the first metallization feature, wherein the second metallization feature has a second shape defined in a cross-section along second direction, the second shape comprising:
a second bottom surface,
a third sidewall extending upward from a first end of the second bottom surface at a third acute angle;
a fourth sidewall extending upward from a second end of the second bottom surface at a first obtuse angle.
