Patent ID: 8502293

Claim:
An embedded metal-insulator-metal (MIM) capacitor for a semiconductor device, the capacitor comprising: a trench disposed in a first dielectric layer disposed above a substrate; a first metal plate disposed along the bottom and sidewalls of the trench and having an uppermost surface; a second dielectric layer disposed on and conformal with the first metal plate, a portion of the first metal plate directly adjacent to the second dielectric layer recessed relative to the sidewalls of the second dielectric layer, wherein the second dielectric layer has an uppermost surface essentially co-planar with the uppermost surface of the first metal plate; a second metal plate disposed on and conformal with the second dielectric layer, a portion of the second metal plate directly adjacent to the second dielectric layer recessed relative to the sidewalls of the second dielectric layer; and a third dielectric layer disposed above the first metal plate, the second dielectric layer, and the second metal plate, and disposed between the first metal plate and the second dielectric layer and between the second metal plate and the second dielectric layer.
