Title: The Innovations of Inventor Toshiro Ono

Introduction

Toshiro Ono, an accomplished inventor based in Isehara, Japan, has made significant contributions to the fields of lithography and thin film technology. With a portfolio of four patents, Ono has established himself as a pioneer in developing advanced methods and apparatus for fabricating high-quality materials.

Latest Patents

Among his latest innovations, Ono has developed an X-ray lithography mask and a method for fabricating the same. This invention features an X-ray absorber layer made from a single layer of high melting point metals like Tantalum (Ta) and Tungsten (W). By forming granular crystal grains on the mask substrate, this technology effectively reduces internal stress within the layer. The resultant fine pattern is created through reactive sputter etching using CBrF3 gas as an etchant, ensuring high dimensional accuracy and a superior pattern contrast.

Additionally, Ono has patented a plasma deposition method and apparatus. This invention includes a plasma formation chamber for introducing gas to create plasma, a specimen chamber for placing substrates, and a target made from sputtering material. Through a coordinated mechanism, ions are extracted from the plasma stream to facilitate the sputtering process, allowing for the formation of high-quality thin films of various metals and compounds at low temperatures. This invention significantly enhances the control over the characteristics of the thin films being produced.
