Title: Innovations by Masato Hara: Pioneering Projection Aligners
Introduction
Masato Hara, based in Tokyo, Japan, is an accomplished inventor known for his significant contributions to the field of optics and photolithography. With a remarkable portfolio of 39 patents, Hara has made a name for himself through innovative designs that enhance the capabilities of projection aligners used in imaging technology.
Latest Patents
Among Hara's latest inventions are two sophisticated projection aligners. The first patent involves a projection aligner that transfers a mask pattern formed on a mask to a substrate using a precise optical system. This system utilizes a collimated light beam emitted from a light source, which passes through the mask and is deflected by a first mirror towards a lens unit. A reflector at the opposite side reflects the light beam back through the lens and toward the substrate, ultimately forming an image of the mask pattern. The size of the image can be adjusted by moving the reflector along the optical axis and the deflector along the light beam's optical path.
The second patent describes a projection aligner that scans multiple light beams over a mask to project an image onto an object. This aligner features several optical systems that include lens units, reflectors, and deflectors. The light beams navigate through the design, ensuring precise image transfer. By adjusting the positions of the reflector and deflector, the size and location of the image on the object can be varied, contributing to the versatility and accuracy of the projection process.
Career Highlights
Masato Hara has held positions in several prestigious companies, such as Asahi Kogaku Kogyo Kabushiki Kaisha and Pentax Corporation.
