Abstract

Method of forming a complex, minute three-dimensional structure, known as micromachining, which includes forming a plurality of thin films at least one of which is provided as a temporary layer composed of a lower layer made of an organic material and an upper layer made of an amphoteric metal material which is formed on the lower layer; and selectively removing the temporary layer to provide a three-dimensional structure. The temporary layer may comprise a composite sacrificial layer of photoresist and aluminum.
