Patent ID: 8125049

Claim:
A metal-insulator-metal (MIM) capacitor comprising: a semiconductor substrate; a dielectric filled trench isolation formed in the semiconductor substrate; a first capacitor plate positioned directly in contact with the trench isolation and positioned within the boundaries of the trench isolation, the first capacitor plate including a polysilicon structure having a surrounding spacer; a silicide layer formed in a first portion of an upper surface of the first capacitor plate; a capacitor dielectric layer formed over a second portion of the upper surface of the first capacitor plate; a contact in an interlayer dielectric (ILD), the contact contacting the silicide layer and a first metal layer over the ILD; and a second capacitor plate over the capacitor dielectric layer, the second capacitor plate including one of: a metal plate formed in the ILD and including an upper surface in direct contact with a lower surface of the first metal layer, or a metal plate formed in the ILD that constitutes part of the first metal layer.
