Abstract:
A method of forming a capacitor, comprising the steps of:forming a first electrically insulating layer having a first conductive contact plug therein, on a semiconductor substrate;forming a first diffusion barrier pattern in electrical contact with the first conductive contact plug;forming a second electrically insulating layer having a contact hole therein, on an upper surface of the first diffusion barrier pattern;forming a first electrode of the capacitor on the second electrically insulating layer, electrically coupled to the first diffusion barrier pattern;forming a dielectric layer on the first electrode; andforming a second electrode of the capacitor on the dielectric layer, opposite the first electrode;wherein said step of forming a first diffusion barrier pattern comprises forming a first diffusion barrier pattern on an upper surface of the first electrically insulating layer.
