Abstract:
1. A manufacturing method of a semiconductor device, comprising: a first thin film layer forming step of, after making a source gas adhere onto a substrate while a temperature of the substrate is lower than a temperature of film forming by a thermal CVD method, supplying a reactant different from the source gas onto the substrate to thereby form a first thin film layer; and a second thin film layer forming step of, after raising the temperature of the substrate up to the temperature of film forming by the thermal CVD method, forming a second thin film layer on the first thin film layer by the thermal CVD method using the source gas, wherein said first thin film layer forming step and said second thin film layer forming step are performed in one reaction chamber, and wherein said first thin film layer forming step is performed in the middle of the substrate temperature increase in which the temperature of the substrate is raised up to the temperature of film forming by the thermal CVD method before the supply of the source gas for forming the second thin film layer.
