Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a first metal-insulator-metal structure comprising:
a first bottom conductor plate,
a first portion of a first dielectric layer over the first bottom conductor plate,
a first middle conductor plate over the first portion of the first dielectric layer,
a first portion of a second dielectric layer over the first middle conductor plate, and
a first top conductor plate over the first portion of the second dielectric layer; and

a second metal-insulator-metal structure comprising:
a second bottom conductor plate,
a second portion of the first dielectric layer over the second bottom conductor plate,
a second middle conductor plate over the second portion of the first dielectric layer,
a second portion of the second dielectric layer over the second middle conductor plate, and
a second top conductor plate over the second portion of the second dielectric layer,

wherein in a cross-sectional view, the first bottom conductor plate is wider than the first middle conductor plate that is wider than the first top conductor plate, and the second bottom conductor plate is narrower than the second middle conductor plate that is narrower than the second top conductor plate.
