Abstract:
1. A method for manufacturing a semiconductor device including the steps of: loading a substrate into a processing chamber; supplying a first raw material, which contains a metal atom, and a second raw material, which contains a silicon atom and a nitrogen atom, into said processing chamber; and forming on said substrate a metal silicate film containing the metal atom and the silicon atom; and unloading from said processing chamber said substrate after film formation; wherein in the step of forming said metal silicate film, a raw material supply ratio of said first raw material and said second raw material is controlled, whereby a concentration ratio of the metal atom and the silicon atom in the resulting metal silicate film is controlled, wherein said second raw material is Si[OCH(CH3)CH2N(CH3)2]4 or Si[OC(CH3)2CH2N(CH3)2]4.
