    摘要: In a method for forming a wiring of a semiconductor device using an atomic layer deposition, an insulating interlayer is formed on a substrate. Tantalum amine derivatives represented by a chemical formula Ta(NR1)(NR2R3)3 in which R1, R2 and R3 represent H or C1-C6 alkyl group are introduced onto the insulating interlayer. A portion of the tantalum amine derivatives is chemisorbed on the insulating interlayer. The rest of tantalum amine derivatives non-chemisorbed on the insulating interlayer is removed from the insulating interlayer. A reacting gas is introduced onto the insulating interlayer. A ligand in the tantalum amine derivatives chemisorbed on the insulating interlayer is removed from the tantalum amine derivatives by a chemical reaction between the reacting gas and the ligand to form a solid material including tantalum nitride. The solid material is accumulated on the insulating interlayer through repeating the above processes to form a wiring.

    摘要: A method forming a tungsten contact can include forming a contact hole in an interlayer dielectric layer to expose a portion of an underlying silicon based substrate and to form a side wall of the contact hole. A tungsten silicide layer can be formed on at least on the exposed portion of the substrate. A tungsten nitride layer can be conformally formed on a surface of the interlayer dielectric layer, on the tungsten silicide layer and on the side wall. A contact tungsten layer can be formed on the tungsten nitride layer to fill the contact hole. Related apparatus and contacts are also disclosed.
