Abstract
The method for forming the microelectronic device having at least one two or three dimensional capacitor includes creating, on a substrate, a plurality of components and a number of superimposed metal interconnection levels. An insulating layer is formed above a metal interconnection level, and a horizontal metal zone of a next metal interconnection level in which one or more of the insulating blocks created from this insulating layer are incorporated is formed therein. The zone is designed to form a lower structural part of the capacitor.
