Abstract
PURPOSE: To manufacture the titled die with a low cost, by drawing an art work picture of a picture pattern having a uniform width which is narrower at the inner side and broader at the outer side, along reference lines showing margins of a circuit pattern.
CONSTITUTION: An art work picture of a picture pattern of a uniform width W in which the width X at the inner side of a reference line S of a circuit pattern is narrowed and the width Y at the outer side is broadened, is drawn by a NC controlled automatic plotter, etc. A photoresist agent is applied on the surface of a steel material 1 in accordance with the art work picture, and a photoresist film 2 is formed after exposing and developing. Then, by performing an etching along the direction of arrow, make the edge of the steel material at the inner depression side below the film 2 reach just front of the reference line S. Then, a liquid acid resistant resin is applied to the inner depression and the resin is baked, so that a resin filled layer 3 is formed for up to the level of the film 2. Then, again the etching is performed along the direction of arrow so that the edge of the steel material at the outer depression may reach just front of the line S. After this procedure, the film 2 and layer 3 are removed, and then, a finish etching is performed along the direction of arrow. Thus a die having an edge 6 whose inner depression 4 is shallower and outer depression is deeper, is completed.
