Abstract:
A method of fabricating a capacitor in a microelectronic device, comprising:forming a recess in a surface of a dielectric layer over a microelectronic substrate; depositing a first barrier layer over the dielectric layer such that the first barrier layer conforms to the recess; depositing a first conductive element over the first barrier layer so as to at least fill the recess; planarizing the dielectric layer to prevent the first barrier layer and the first conductive element from extending outwardly of the recess following deposition of the first conductive element; depositing a second barrier layer over the first conductive element such that the first barrier layer and the second barrier layer cooperate to encapsulate the first conductive element, the first conductive element comprising a first plate of the capacitor; depositing a capacitor dielectric layer over the second barrier layer; depositing a second conductive element over the capacitor dielectric layer, the second conductive element comprising a second plate of the capacitor.
