Classification: CPC H | IPC H

Claim 16:
17. A semiconductor structure, comprising:
a substrate;
a first metal layer over the substrate;
a first insulating layer over the first metal layer;
a second metal layer over the first insulating layer;
a second insulating layer over the second metal layer; and
a third metal layer over the second insulating layer,
wherein a first metal-insulator-metal structure includes a first portion of the first metal layer, a first portion of the second metal layer, and a first portion of the third metal layer that are stacked vertically one over another, wherein a second metal-insulator-metal structure includes a second portion of the first metal layer, a second portion of the second metal layer, and a second portion of the third metal layer that are stacked vertically one over another,
wherein in a cross-sectional view, the first portion of the first metal layer is wider than the second portion of the first metal layer, the first portion of the third metal layer is narrower than the second portion of the third metal layer, the first portion of the first metal layer is wider than the first portion of the second metal layer, and the second portion of the first metal layer is narrower than the second portion of the second metal layer.
