    Abstract: A spin coating apparatus, system, and/or method that increase the uniformity of a coating material on a substrate. The spin coating system may be specifically directed for use with polygonal shaped substrates. The spin coating system may include a process chamber within which the substrate is located, spinning on a chuck, during operation. The spin coating system may include gas injection ports that inject a gas into the process chamber so that the gas contacts the substrate along corner portions of its front surface. This injection of the gas increases pressure and prevents excessive build-up of the coating material that may otherwise occur when spin coating polygonal shaped substrates.

    Abstract: Provided is a three-dimensional structure that makes it possible to obtain a coating film having a uniform thickness and good adhesion even when a three-dimensional structure main body has a concave section and/or a convex section, and that therefore has high durability without the coating film being peeled off even after long-term use. The three-dimensional structure has a three-dimensional structure main body and a coating film having a thickness of 10 nm to 300 nm and formed on a surface of the three-dimensional structure main body, wherein the coating film is made of a metal alkoxide or non-metal alkoxide hydrolysis product; and when a portion of the coating film located on a surface of the concave section and/or convex section in the three-dimensional structure main body is observed with a scanning electron microscope at a magnification of 300, no peeling of the coating film can be recognized.

    Abstract: A substrate processing apparatus includes a substrate heating unit arranged to heat the underside of a substrate while supporting the substrate thereon and an attitude changing unit arranged to cause the substrate heating unit to undergo an attitude change between a horizontal attitude and a tilted attitude. In an organic solvent removing step to be performed following a substrate heating step of heating the substrate, the substrate heating unit undergoes an attitude change to the tilted attitude so that the upper surface of the substrate becomes tilted with respect to the horizontal surface.

    Abstract: A developing method includes: forming a liquid pool of a diluted developing solution diluted with pure water in a central portion of a substrate; forming a liquid film of the diluted developing solution on a surface of the substrate by accelerating rotation of the substrate to diffuse the liquid pool of the diluted developing solution on the entire surface of the substrate; and then supplying a developing solution onto the substrate. Supplying a developing solution includes: supplying the developing solution from a developing solution supply nozzle having a liquid contact surface while securing a gap having a predetermined size between the developing solution supply nozzle and the substrate; and moving the developing solution supply nozzle in a radial direction passing through a center of the substrate while forming a liquid pool of the developing solution between the substrate and the liquid contact surface of the developing solution supply nozzle.
