    摘要: A method of forming a metal thin film can reduce leakage current while improving electric properties by improving step coverage of a device. The method of forming a metal thin film includes supplying a metal precursor including chlorine, purging byproducts produced after the supplying of the metal precursor by injecting a purge gas, supplying a reactant to allow the reactant and the metal precursor to react with each other to form a thin film layer, and purging the byproducts produced after the reaction by injecting a purge gas, wherein before the supplying of the metal precursor, the method further includes supplying a reactant to be adsorbed on a treated product.

    摘要: Methods of fabricating a semiconductor device include forming a deposited film on a semiconductor substrate in a process chamber by repeatedly forming unit layers on the semiconductor substrate. The unit layer is formed by forming a preliminary unit layer on the semiconductor substrate by supplying a process material including a precursor material and film-control material into the process chamber, purging the process chamber, forming a unit layer from the preliminary unit layer, and again purging the process chamber. The precursor material includes a central atom and a ligand bonded to the central atom, and the film-control material includes a hydride of the ligand.
