Abstract:
PROBLEM TO BE SOLVED: To provide for a method and device for fabricating microscale and nanoscale structures. SOLUTION: The method for fabrication of microscopic structures that uses a beam process, such as beam-induced decomposition of a precursor, to deposit a mask in a precise pattern and then a selective, plasma beam is applied, comprising the steps of first creating a protective mask upon surface portions of a substrate using a beam process such as an electron beam, focused ion beam (FIB), or laser process, and secondly etching unmasked substrate portions using a selective plasma beam etch process. Optionally, a third step comprising the removal of the protective mask may be performed with a second, materially oppositely selective plasma beam process. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To increase the throughput of manufacturing a microstructure. SOLUTION: In a first material and a second material attached together, the first material is liable to be ablation with laser beams than the second material. In other words, the ablation threshold of the first material is higher than that of the second material. For example, the first material is silicon, and the second material is polymer-on-silicon consisting of polyimide. A removal process for performing the micro-working of opening a non-through hole in a laminate comprises a step of irradiating laser beams on the first material, and removing the material close to the interface of the two materials while a small amount of the first material is remained on a hole bottom, and a step of removing the rest of the first material by irradiating, from the second material side, laser beams of the intensity not influencing the second material, in other words, laser beams of the ablation influence lower than the ablation threshold of the second material.

Abstract:
PROBLEM TO BE SOLVED: To provide a precision laser machining method of a fine structure including an hyperfine structure using a near field scanning optical microscope (NSOM). SOLUTION: In a method for manufacturing a micro device using this NSOM laser fine machining device, fine structure preforms 112 including existing features are provided. A NSOM probe tip is scanned over the selected preforms 112 so that a plurality of scanning lines may cross the existing features. In at least two scanning lines, scanning positions of the existing features are determined. Based on the scanning positions and shapes of the existing features, the directions of the existing features are determined. At least an expected machining position of a succeeding scanning line is determined. When the NSOM probe 110 is scanned by the expected machining position during the succeeding scanning line, fine machining laser 102 is radiated, at least a feature on the fine structure device preforms is formed to complete the fine structure device.

PROBLEM TO BE SOLVED: To provide an ion beam micromachining method for forming a fine circuit pattern used for a quantum device on the surface of a Ga x In 1-x As y P 1-y surface, without the need for previously removing a surface oxide film of As 2 O 3 , As 2 O, Ga 2 O, etc., naturally formed on the surface of the Ga x In 1-x As y P 1-y layer containing GaAs nor forming a mask for dry etching for forming a complicated fine circuit pattern. SOLUTION: After Ga ions, controlled to an arbitrary ion beam diameter and ion current density are injected into the surface of the Ga x In 1-x As y P 1-y (0≤x, y≤1) which includes a single-body GaAs and InP substrate to substitute an oxide layer for Ga 2 O 3 or Ga 2 O or product it by Ga ion implantation, in the presence of a surface oxide film formed on the surface of the Ga x In 1-x As y P 1-y layer or by oxide molecule irradiation, the surface of the Ga x In 1-x As y P 1-y layer is etched on a dry basis in a single-atom layer units with a brominated body to remove the surface oxide film other than the part substituted for Ga 2 O 3 or Ga 2 O and the Ga x In 1-x As y P 1-y layer.
