发明名称 Method of forming an ohmic layer and method of forming a metal wiring of a semiconductor device using the same
摘要 A metal organic precursor represented by a formula of R1-CpML is provided onto a substrate having a conductive pattern including silicon. Here, R1 is an alkyl group substituent of Cp, R1 including methyl, ethyl, propyl, pentamethyl, pentaethyl, diethyl, dimethyl or dipropyl, Cp is cyclopentadienyl, M includes nickel (Ni), cobalt (Co), titanium (Ti), platinum (Pt) zirconium (Zr) or ruthenium (Ru), and L is at least one ligand, the at least one ligand including a carbonyl. A deposition process is performed using the metal organic precursor to form a preliminary metal silicide layer and a metal layer on the substrate. The preliminary metal silicidation layer is formed on the conductive pattern. The preliminary metal silicide layer is transformed into a metal silicide layer.
