Abstract:
1. A method of manufacturing a semiconductor device comprising: forming a first high dielectric constant insulating film over a semiconductor substrate; forming a second high dielectric constant insulating film over the first high dielectric constant insulating film; adhering Al to a surface of the second high dielectric constant insulating film to thereby form an Al adhered layer on the surface of the second high dielectric constant insulating film; forming a conductive film containing Si over the second high dielectric constant insulating film with the Al adhered layer formed on the surface; and patterning the conductive film to form a gate electrode of the conductive film, wherein in forming the Al adhered layer, an organic aluminum compound is sprayed to the surface of the second high dielectric constant insulating film to thereby adhere Al to the surface of the second high dielectric constant insulating film.
