Claim Text:
1. A method for processing a substrate, the substrate comprising an organic film pattern, the method comprising: a fusion/deformation step of fusing said organic film pattern to deform the fused organic film pattern; and a third removal step of removing at least a part of the fused and deformed organic film pattern; wherein the substrate further comprises a semiconductor film and a metal film, said metal film is formed on said semiconductor film, said organic film pattern is formed on the metal film, the organic film pattern is a resist pattern, and the method further comprises: a first etching step of etching said metal film with said resist pattern being used as a mask; said first etching step being carried out before said fusion/deformation step; wherein said etched metal film and said fused and deformed organic film pattern form a joint resist mask, the method further comprises: a second etching step of etching said semiconductor film with said joint resist mask, said second etching step being carried out after said fusion/deformation step before said third removal step; wherein said metal film is turned into a source electrode and a drain electrode of a thin film transistor (TFT) by said first etching step; wherein the method further comprising: a third etching step of etching said semiconductor film to form a channel of the said TFT, the third etching step being carried out after said third removal step.
