Abstract:
1. A method for forming a pattern, comprising: forming a photosensitive layer comprising a photosensitive composition on a substrate; selectively irradiating the photosensitive layer with at least one of an ultraviolet ray and an ionizing radiation; subjecting the substrate to heat treatment; and developing the photosensitive layer to remove selectively an irradiated area of the photosensitive layer after the heat treatment; wherein the photo sensitive composition comprises: a first polymer material comprising a group having a structure represented by the following general formula (2):  wherein m represents an integer of 0 or more, a second polymer material comprising a group having a structure represented by the following general formula (3),  wherein n represents an integer of 1 or more, wherein Z is selected from the group consisting of —O—, —S—, —SO a photo acid generator generating an acid with at least one of an ultraviolet ray and an ionizing radiation.
