Abstract:
1. A method for forming a semiconductor device having a planar metal-insulator-metal (MIM) capacitor comprising: providing a semiconductor substrate; forming a plurality of layers of copper conductors over the semiconductor substrate, wherein a layer of the plurality of layers of copper conductors are formed over another layer of the plurality of layers of copper conductors, and each layer being separated from the semiconductor substrate and other layers of the plurality of layers of copper conductors by a plurality of inter-level dielectric layers; forming a first insulating layer over the plurality of layers of copper conductors; planarizing the first insulating layer; forming a second insulating layer over the first insulating layer; forming a first plate electrode for the planar MIM capacitor over the second insulating layer and directly over more than one conductor of each of the plurality of layers of copper conductors; forming a third insulating layer over the first electrode; and forming a second plate electrode for the planar MIM capacitor over the third insulating layer.
