Title:
電子回路基板及びその製造方法
Document Type and Number:
Japanese Patent JP4746557
Kind Code:
B2
Abstract:
A production process for making an electronic circuit substrate comprising: a patterning step of forming a respectively anodically oxidizable conductor pattern and distribution pattern connected to the conductor pattern on a substrate; and an anodic oxidation step of generating an oxide film from the conductor pattern and the distribution pattern by contacting an electrolyte solution with the conductor pattern and the distribution pattern and carrying out anodic oxidation while applying current thereto, the patterns serving as anodes, wherein the width or film thickness of the distribution pattern is at least partially set so that an insulator portion is formed in the anodic oxidation step in which an oxide film formed on one of the side walls of the distribution pattern is integrated with an oxide film formed on the other side wall.
