Abstract: PURPOSE: A method for removing a photoresist layer pattern is provided to easily remove polymer and a photoresist layer by minimizing a hardening phenomenon of the photoresist layer damaged by plasma of high potential. CONSTITUTION: A plasma etch process with a high potential is performed on a substrate by using a photoresist layer pattern as a mask to form a via hole of a fine size, and the photoresist layer pattern damaged by the plasma is eliminated. In batch-type photoresist layer stripper equipment, an O radical treatment is performed at a low temperature of 50-70 deg.C to eliminate the photoresist layer pattern. The O radical treatment is performed on the resultant structure at a high temperature of 120-200 deg.C to weaken the inner cohesion of polymer formed on the sidewall of the via hole.
