Title: Shigetomo Ishibashi: Innovator in Projection Aligner Technology
Introduction
Shigetomo Ishibashi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technology, particularly in the development of projection aligners. With a total of 4 patents to his name, Ishibashi's work has advanced the capabilities of imaging systems used in various applications.
Latest Patents
Ishibashi's latest patents include innovative designs for projection aligners. The first patent describes a projection aligner that transfers a mask pattern formed on a mask to a substrate. In this design, a collimated light beam is emitted from a light source toward the mask. The light beam passes through the mask and is deflected by a first mirror toward a lens unit. A reflector is positioned on the opposite side of the lens unit to reflect the light beam back through the lens, allowing for precise image formation on the substrate. The size of the image can be adjusted by moving the reflector along the optical axis.
The second patent outlines a projection aligner that scans multiple light beams over a mask in a main scanning direction. This design enables the transfer of an image of a mask pattern onto an object using light beams that pass through the mask. Each optical system within the aligner includes a lens unit, a reflector, and a deflector. The light beam is deflected, passes through the lens, and is reflected back, allowing for adjustments in image size and location on the object.
