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.
