Abstract:
A method for fabricating a ruthenium (Ru) thin layer comprising:loading a substrate into a reaction chamber for an atomic layer deposition; injecting RuXn into the reaction chamber, wherein n is 2 or 3, and adsorbing the RuXn onto a surface of the substrate wherein X is a material selected from the group consisting of hydrogen (H), C1ËœC10 alkyl, C2ËœC10 alkenyl, C1 C8 alkoxy, C6ËœC12 aryl, diketonates, cyclopentadienyl, C1 C8 alkylcyclopentadienyl and derivatives thereof including one or more halogen groups; and injecting a reaction gas reductive to the RuXn into the reaction chamber.
