Abstract:
1. A method for manufacturing a semiconductor device, comprising: forming a non-photosensitive black resin layer over a substrate; forming a positive resist film over the non-photosensitive black resin layer; exposing a portion of the positive resist film to a light; developing the positive resist film and etching the non-photosensitive black resin layer wherein a first developing solution is used for the developing to remove the exposed portion of the positive resist film to form a resist pattern and is used for the etching to remove a portion of the non-photosensitive black resin layer under the removed portion of the positive resist film to form a resin black matrix under the resist pattern; exposing the resist pattern which remains after the removal of the exposed portion of the positive resist film to a light; and removing the resist pattern by using a second developing solution to leave the resin black matrix behind.
