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.
