Outline of Final Research Achievements

New technologies for fabricating micro-parts used in medical and biochemical fields were developed by combining lithography onto stainless steel pipes with small diameters and etching. The lithography is a technology for printing fine patterns by exposing to light and developing sensitized parts of a resist film. The etching is a technology for dissolving parts of materials without covered by the resist patterns. After coating stainless-steel pipes with diameters of 2 mm and 100 μm, fine patterns were printed or delineated on the resist film, and the pipes were etched by using the resist patterns as etching masks. As a result, fine micro-parts imitating medical stents used for reinforcing half damaged blood vessels, fine pipes with multi-holes or multi-slits for the use of filtering or selection of bio-materials were fabricated. Technology for non-destructively inspecting air-bearing grooves fabricated on inner surfaces of pipes aiming dental high-speed spindles was also developed.
