发明名称 Substrate developing method, substrate processing method and developing solution supply nozzle
摘要 According to the present invention, an anti-reflective film formed under a resist film is removed in a photolithography process of a wafer without affecting the resist film. According to the present invention, in a photolithography process of a substrate, an anti-reflective film having solubility in the developing solution is formed and thereafter a resist film is formed. In development treatment after exposure processing, a developing solution is supplied to the substrate to develop the resist film. At an instant when the development of the resist film is finished, a second developing solution lower in concentration than the developing solution is supplied to the substrate. Only the anti-reflective film is dissolved and removed by the supply of the second developing solution.
