Claim 15:
16. An interconnect structure comprising:
a first metal layer over a first dielectric layer, the first metal layer comprising a first metal structure and a second metal structure spaced apart from the first metal structure, the first and second metal structures extending along a first direction;
a second dielectric layer over the first metal layer;
a via structure extending from the second dielectric layer into a slot between the first metal structure and the second metal structure of the first metal layer, the via structure having a bottom surface above a bottom surface of the first dielectric layer and below a top surface of the first dielectric layer, and the bottom surface of the via structure is in contact with a recessed region in the first dielectric layer; and
a second metal layer over the via structure, wherein from a top view the second metal layer has a linear pattern extending along a second direction different from the first direction, wherein from the top view, the linear pattern of the second metal layer extends beyond an entire width of the first metal structure.
