Title: Youichi Hirabayashi: Innovator in Projection Exposure Technology
Introduction
Youichi Hirabayashi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of projection exposure technology, holding a total of 3 patents. His innovative work has advanced the capabilities of optical systems used in various applications.
Latest Patents
Hirabayashi's latest patents include a projection exposure device and a position alignment device and method. In his position alignment device, a mask mark is irradiated by an ultra-violet light source. The image of the mark is then passed through a lens and a half-mirror, reflected by a mirror, and further passed through a beam splitter and a lens, forming an image on a CCD. The center coordinate of the image is measured by a device. Subsequently, a board mark is illuminated by an infrared light source, and its image is processed similarly, allowing for precise positional alignment by moving the mobile stage in the XYθ directions based on the board mark on the infrared CCD and the mask mark on the ultra-violet CCD.
