Title: A Dive into the Innovations of Tomoki Suemasa

Introduction

Tomoki Suemasa, an accomplished inventor based in Yamanashi, Japan, has made significant contributions to the field of gas treatment and oxide etching technology. With a total of six patents to his name, Suemasa's innovative approaches have enhanced the efficiency and effectiveness of gas processing methods in industrial applications.

Latest Patents

Among Suemasa's latest inventions is a gas treatment method that intricately describes a process where a workpiece is mounted on a platform within a chamber. Here, a silicon oxide film is formed on the workpiece's surface. Utilizing HF gas and NH gas as reaction gases, these are discharged onto the workpiece from several gas discharge holes located on a shower plate. This treatment triggers a reaction between the gases and the silicon oxide film, followed by the heating and removal of the resultant reaction product through decomposition, completing the etching process.

Additionally, Suemasa has developed an oxide etching method that involves loading an object with a patterned silicon oxide film into a chamber. The method allows for the supply of HF gas and NH gas, along with a diluent gas, to conduct a reaction treatment. By increasing the flow rate of the diluent gas to a predetermined chamber pressure, Suemasa ensures that no etching residue remains post-heating, achieving high verticality in the etching shape.
