Abstract:
A method of forming a resist pattern, comprising the steps of:(a) applying a resist to an object surface; (b) subjecting the resist to pattern exposure by irradiating the resist with light directed through a first reticle; (c) developing the resist, wherein the developed resist pattern has first regions not to be shrunk in which a plurality of patterns having intervals that are smaller than a predetermined distance are provided, and second regions to be shrunk at a predetermined shrinkage rate in which a plurality of patterns having intervals that are larger than a predetermined distance are provided; (d) providing the first regions not to be shrunk with resistance to shrinkage during a bake process by irradiating the resist with light directed through a second reticle, the light only reaching said first regions; (e) adjusting a shrinkage rate of the resist pattern by irradiating the entire resist with light; and (f) baking the resist.
