Zusammenfassung:PROBLEM TO BE SOLVED: To remove an antireflection film formed on an underlayer of a resist film so as not to influence the resist film, in a photolithography step of a wafer. SOLUTION: In a photolithography step of a wafer W, an antireflection film B having solubility in a developer solution is formed, and thereafter a resist film R is formed. At the time of development processing after exposure processing, a developer solution H1 is fed to the surface of the wafer W, to develop the resist film R. At the time of finishing the development of the resist film R, a developer solution H2 having lower concentration than that of the developer solution H1 is fed to the surface of the wafer W. Only the antireflection film B is dissolved and removed by feeding of this developer solution H2. COPYRIGHT: (C)2009,JPO&INPIT
