Abstract

PURPOSE: To easily obtain dies of always stable high quality, by using trimming pattern photo mask and other one pattern photo mask capable of easily forming etching resist pattern and positioning quickly.
CONSTITUTION: A photo mask A3 has inner and outer trimming lines of width a1 subtracting the double dimension of blade width v and shallow side etching amount from a desired circuit width a, and width a2 adding deep side etching amount to the width a. By using this mask, an etching resist 23 is provided on a metal original plate 22. Next, a photo mask A4 having a trimming line of width a3 which is in the relation of a1≤a3≤a2 is laid over the resist 23 to form a resist 24, and a deep groove 29 is formed by etching deeply. The resist 24 is separated, and the metal plate on which the resist 23 is provided is etched shallowly to form a shallow groove 28. Meanwhile, the mask A3 has the trimming line formed at high precision photographically by the pin-fitting method using a register punch.
