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

Claim 6:
7. A semiconductor structure comprising:
a semiconductor substrate;
a first metallization feature over the semiconductor substrate, wherein the first metallization feature includes a first bottom corner and a second bottom corner opposite to the first bottom corner;
a second metallization feature over the semiconductor substrate, wherein the second metallization feature includes a third bottom corner and a fourth bottom corner opposite to the third bottom corner;
a first dielectric feature between the first metallization feature and the second metallization feature; and
a second dielectric feature adjacent to the first metallization feature at a side opposite to the first dielectric feature, wherein
the first metallization feature, the second metallization feature, the first dielectric feature, and the second dielectric feature are arranged along the same direction,
the first bottom corner of the first metallization feature is adjacent to the first dielectric feature and defined by an acute angle, and
the third bottom corner of the second metallization feature is adjacent to the first dielectric feature and defined by an acute angle; and wherein at least one of the second bottom corner or the fourth bottom corner is defined by an obtuse angle.
