Yukio Morishige is a highly accomplished inventor based in Tokyo, Japan. With an impressive track record, he holds 30 patents in various fields of technology. His latest patents include the following:
1. SiC Wafer Producing Method: This patent describes a method for producing a Silicon Carbide (SiC) wafer from an SiC ingot. The technique involves using a laser beam to create a modified layer parallel to the end surface of the ingot, which then forms cracks leading to a separation start point. By precisely controlling the focal point and numerical aperture of the laser beam, the desired thickness and quality of the SiC wafer can be obtained.
2. Laser Processing Method and Laser Processing Apparatus: In this invention, Morishige presents a laser processing method focused on creating a modified layer inside a workpiece. By irradiating the workpiece with a laser beam of a specific wavelength, which is transmitted through the material, a focal point is positioned within the workpiece. The key aspect of this technique lies in setting the spectral line width of the laser beam to be equal to or smaller than 10 pm.
Throughout his career, Yukio Morishige has collaborated with several prominent companies, including:
1. DISCO Corporation: DISCO is a leading global manufacturer of precision cutting, grinding, and polishing machines. Morishige has worked closely with the company, contributing his expertise in laser processing techniques.
2. Laserfront Technologies, Inc.: Laserfront Technologies is a Japanese company specializing in laser and optical technologies. Morishige's association with this company has allowed him to further explore advanced laser processing methods.
Within these companies, Morishige has had the opportunity to work with talented individuals such as Yusuke Nagai and Satoshi Kobayashi, who have likely played significant roles in the development of his patented inventions.
Yukio Morishige's contributions have undoubtedly advanced the field of laser processing and SiC wafer production methodologies. His innovative ideas and dedication to technological advancements serve as an inspiration to aspiring inventors and inventors alike.
