Abstract:
A method of fabricating an integrated circuit capacitor includes forming a first metal layer on a conductive plug in an interlayer insulating layer on a substrate. At least a portion of the first metal layer is silicided to form a metal silicide layer and a remaining first metal layer on the conductive plug. The remaining first metal layer is removed using a dry etching process. A lower electrode including a second metal layer is then formed on the metal silicide layer. Because the remaining first metal layer is removed, etching and/or other damage to the conductive plug and/or the interlayer insulating layer during a subsequent wet ethching process may be reduced and/or prevented.
