Patent ID: 7112507

Claim:
A metal-insulator-metal (MIM) capacitor plate, comprising: a first conductive layer having a first surface and a thickness of between about 2500 Å to 3000 Å the first conductive layer comprising a first material; at least one thin conductive material layer having a first surface and a second surface, and a thickness of between about 50 Å and 450 Å disposed over the first conductive layer, such that said second surface of said at least one thin conductive layer is in direct contact, including electrical contact, with the first surface of said first conductive layer, the thin conductive material layer comprising a second material, the second material being different than the first material; and at least one second conductive layer having a second surface and a thickness of between about 500 Å and 3000 Å disposed over at least one of the at least one thin conductive material layers, such that said second surface of said at least one second conductive layer is in direct contact, including electrical contact, with the first surface of said at least one thin conductive layer, wherein each of the first conductive layer, the at least one thin conductive layer and the at least one second conductive layer are electrically coupled together to form said MIM capacitor plate and are each patterned to have outer edges that are aligned relative to one another.
