Patent ID: 8492258

Claim:
A substrate processing apparatus, comprising: a processing chamber in which a substrate of which a high dielectric constant insulating film is formed on a surface through an insulating film is processed; a first source supply system that supplies a first source containing aluminum atoms into the processing chamber; a second source supply system that supplies a second source containing titanium atoms into the processing chamber; a reactive gas supply system that supplies a reactive gas containing nitrogen atoms into the processing chamber; a heater that heats the substrate in the processing chamber; and a controller configured to control the first source supply system, the second source supply system, the reactive gas supply system, and the heater, so that an aluminum nitride titanium film is formed on the high dielectric constant insulating film formed on the substrate by alternately repeating formation of an aluminum nitride film by supplying the first source and the reactive gas into the processing chamber, and formation of a titanium nitride film by supplying the second source and the reactive gas into the processing chamber, and at that time, so that the aluminum nitride film is formed firstly and/or lastly.
