Abstract:
1. A developing method comprising the steps of: forming an anti-reflective film on a substrate and forming a resist film on the anti-reflective film, portions of said resist film being in a pattern, and thereafter; mixing a liquid with a developing solution to form a produced developing solution, depositing the produced developing solution onto said resist film, said produced developing solution dissolving said portions of the resist film, and thereafter; mixing the liquid with the developing solution to form an adjusted developing solution, depositing the adjusted developing solution onto said anti-reflective film and onto remaining portions of the resist film, said adjusted developing solution dissolving said anti-reflective film faster than dissolving said remaining portions of the resist film, wherein at least one property of the adjusted developing solution is lower than one property of the produced developing solution, in at least one property being from a group consisting of a concentration and a temperature.
