    摘要: Contacts having different characteristics may be created by forming a first silicide layer over a first device region of a substrate, and then forming a second silicide layer over a second device region while simultaneously further forming the first silicide layer. A first contact hole may be formed in a dielectric layer over a first device region of a substrate. A silicide layer may then be formed in the first contact hole. A second contact hole may be formed after the first contact hole and silicide layer is formed. A second silicidation may then be performed in the first and second contact holes.

    摘要: 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.
