Abstract: A substrate processing system which sprays exposure process gas onto a substrate disposed within a chamber. The substrate processing system is used, for example, for performing an exposure process of an organic film formed on a substrate in a gas atmosphere obtained by vaporizing an organic solvent solution for dissolving and reflowing an organic film. The substrate processing system comprises: the chamber having at least one gas inlet and at least one gas outlets; a gas introducing means which introduces the exposure process gas into the chamber via the gas inlet; and a gas distributing means. The gas distributing means separates an inner space of the chamber into a first space into which the exposure process gas is introduced via the gas inlet and a second space in which the substrate is disposed.

Abstract: A process for forming a pattern contains steps of: forming a first mask pattern on a film to be etched on a substrate; forming a first pattern of the film to be etched by using the first mask pattern as a mask; forming a second mask pattern having a plane shape different from that of the first mask pattern by deforming the first mask pattern; and forming a second pattern of the film to be etched different from the first pattern by using the second mask pattern. By applying the process for forming a pattern, for example, to the formation of a semiconductor layer and source and drain electrodes of a TFT substrate of a liquid crystal display apparatus, the above-stated formation requiring two photoresist process steps in a conventional manufacturing method of a liquid crystal display apparatus can be carried out by only one process step, thereby reducing manufacturing cost thereof.

Abstract: Issues To provide a new etching method which is able to control and adjust a taper angle of etched base film pattern in wide range and with high accuracy, while avoiding peeling off of an organic mask by etching the base film using the organic mask for the etching, while the organic mask is being coordinated so that the organic mask has sufficient adhesion strength with the base film at the central part of the organic mask, while the adhesion strength at the periphery is low. (Method for Solving the Issues) By contacting the organic pattern with organic solvent, the adhesion strength between the base film and the bottom of organic solvent permeated portion located at the periphery of organic pattern becomes low. After that, by conducting a heat treatment for adjusting the adhesion strength, the organic pattern having the adjusted adhesion strength at the periphery is formed. Using the organic pattern as a mask, isotropic etching is conducted.
