Abstract:
A method of forming a predetermined resist pattern on a substrate coated with an undercoat, comprising the steps of:(a) detecting a light reflectivity of the undercoat; (b) coating a resist on the substrate based upon a predetermined rotation speed of the substrate; (c) exposing the substrate coated with the resist based upon a predetermined exposure time; (d) developing the exposed substrate based upon a predetermined developing time; (e) storing a plurality of data including light reflectivity, rotation speed, exposure time, and developing time with a predetermined relation therebetween; and (f) controlling at least one of the predetermined rotation speed, the predetermined exposure time, and the developing time by using at least one of the stored corresponding data based upon the detected reflectivity according to the predetermined relation therebetween.
