Abstract
PURPOSE: To provide the subject method comprising the steps of: providing partitions consisting of photoresists the intervals of which are defined on the substrate, applying metal films on the partitioned regions, and removing by etching metal films in the unnecessary partitions while masking the partitioned regions with the resists thereby to obtain a fine metal wiring.
CONSTITUTION: If the substrate 1 is made of a material unable to be electroplated, a plated layer 2 which becomes a surface layer is firstly applied thereon, and there are formed thereon partitions 7 consisting of plating photoresist images having a width d of less than 10μm at an interval of l the same as the width t of the fine image 5 formed subsequently. Then, while the layer 2 encircled by partitions 7 is subjected to photoresist coat plating to form the metal film 3, the film 3 is divided into two parts 3a and 3b without adhering to the partitions 7. Thereafter, an etching photoresist image 8 containing the upper parts of partitions 7 at both sides are removed by etching using the image 8 as a mask. Then, the partitions 7 and the image 8 are removed, and only the fine image 5 having the width t being caused to remain at the central part.
