Abstract:
A method for processing a three-dimensional structure, comprising the steps of:depositing a thin layer for absorption of laser light on a flat substrate; depositing a transparent layer on said thin layer for absorption of laser light; and radiating a process laser light, passing through said transparent layer to said thin layer and absorbing it in said thin layer; wherein pulse injection energy of said process laser light is set to be the same as or smaller than the maximum pulse injection energy capable of exposing a flat surface of said thin layer for absorption of laser light at an interface between said thin and said transparent layers, and set to be the same as or greater than the minimum pulse injection energy capable of removing said transparent layer.
