Abstract:
1. A microstructure manufacturing method comprising: forming a first insulating film on an Si substrate; exposing an Si surface by removing a part of the first insulating film; forming a recessed portion by etching the Si substrate from the exposed Si surface; forming a second insulating film on a sidewall and a bottom of the recessed portion; forming an Si exposed surface by removing at least a part of the second insulating film formed on the bottom of the recessed portion; and filling the recessed portion with a metal by electrolytic plating, wherein the electrolytic plating is performed by energizing the Si exposed surface through the Si substrate, and wherein the metal is deposited from the Si exposed surface by the electrolytic plating.
