CIRCUIT PATTERN FORMATION METHOD, PHOTOMASK, PHOTOMASK PRODUCTION METHOD, AND PRODUCTION METHOD OF ELECTRIC ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a circuit pattern formation method, in which a substrate on which a circuit pattern is formed, can be produced by mass production.SOLUTION: A circuit pattern formation method comprises: a step S2 for performing pretreatment for molecule adhesion to a substrate 12 on which a non-flat surface 13 is formed; a step S5 for adhering a conductor 14 to the non-flat surface of the substrate 12 which has been subjected to pretreatment; and a step S7 for, using a photomask PM having a shape corresponding to the non-flat surface, and forming a circuit pattern on the non-flat surface 13 by photo lithography.SELECTED DRAWING: Figure 1
