Abstract:
1. A resin layer formation method for forming a resin layer on a surface of a substrate, with a resin layer applying apparatus having a rotatable turntable comprising the steps of: providing a substrate having a planar surface on the substrate; mounting the substrate on the rotatable turntable; applying a first coating of a resin on the surface of said substrate; forming a first resin flowable layer on the surface of said substrate by rotating said substrate on the turntable; forming a hardened non-flowable adjustment section of the first resin layer around a rotation center of said substrate by hardening a part of said first resin flowable layer; applying a second coating of the resin at the rotation center side from said hardened adjustment section of said substrate or on said hardened adjustment section; and forming a second resin layer on said first resin layer by rotating said substrate on the rotatable turntable, wherein a substantially uniform thickness of the combined first and second resin layer is provided over the substrate, wherein said resin is an ultraviolet-hardening resin, and said hardened adjustment section is formed by irradiating ultraviolet radiation on a part of the first resin coating of said substrate, and a plurality of hardened adjustment sections are formed by irradiating ultraviolet radiation on a plurality of separate areas of the first resin coating on said substrate by using a movable ultraviolet irradiation section.
