Abstract:
1. A method of making a microelectronic device having at least one capacitor, the method comprising: forming, on a substrate, a plurality of components and a number k (where k≧1) of superimposed metal interconnection levels; forming a first insulating layer above the k forming, in the first insulating layer, a horizontal metal zone for a k+1 forming a second insulating layer above the k+1 forming, in the second insulating layer, a plurality of slots exposing portions of the horizontal metal zone; and covering side walls and a bottom of the slots with a metal-insulator-metal (MIM) stack including at least one first metal layer, at least one dielectric layer on the at least one first metal layer, and at least one second metal layer on the at least one dielectric layer.
