Abstract:
A liquid immersion lithography apparatus includes a projection system having an optical member of which an incidence side has a convex lens shape, and a flow passage connected to a hole from which liquid is supplied. A substrate is exposed through the liquid covering only a portion of an upper surface of the substrate. The optical member has an end surface via which the exposure light is projected to the substrate via the liquid. A material having the end surface is fused silica.
