Abstract:
A method for manufacturing a semiconductor device is provided to improve the efficiency of a process by using a source containing Sr(C5(CH3)5)2 when forming a conductive oxide layer of a Perovskite structure. A substrate(10) is prepared. A first source containing Sr(C5(CH3)5)2, a second source containing Ru, and reactive gas are supplied to the substrate to form a conductive oxide layer(45) of a Perovskite structure on the substrate. The second source is one selected from Ru(tmhd)3, Ru(mhd)3, Ru(od)3, Ru(cp)2, Ru(Mecp)2, and Ru(Etcp)2. The conductive oxide layer is SrRuO3. The reactive gas is O3, O2, or H2O. The supplying of the first source, the second source, and the reactive gas is performed by an ALD(Atomic Layer Deposition) method. Alternatively, the supplying of the first source, the second source, and the reactive gas is performed by a CVD(Chemical Vapor Deposition) method.
