Abstract
A post lithography resist treatment apparatus for treating a substrate having a resist layer thereon with a fluid layer thereover includes at least one post exposure bake chamber having a substrate support having a substrate support surface thereon, and an electrode, the electrode comprising an electrode body having a substrate support facing side, the substrate support facing side having at least one recess extending inwardly thereof, and at least one projection adjacent to the recess having a substrate support facing surface thereon, wherein the substrate support is moveable to position a substrate, when supported thereon, such that an fluid layer disposed on the substrate contacts the substrate support facing surface of the projection but does not fill the recess with fluid, and the substrate facing surface of the electrode body is spaced from the substrate.
