His innovative work has impacted various industries, particularly in semiconductor technology and video processing.
Latest Patents
One of Hitoshi Iida's latest patents is a particle detection method and apparatus. This invention involves an apparatus and method for detecting the presence of particles on the surface of an object, such as a patterned semiconductor wafer. A vertically expanded, horizontally scanning beam of light is directed onto the surface at a grazing angle of incidence. A video camera positioned above the surface detects light scattered from any particles present, while minimizing specularly reflected light. The surface is angularly prepositioned relative to the incident light beam to reduce diffracted light from the surface and the pattern of lines on it. The object is then moved translationally to examine the entire surface or selected portions, one area at a time.
Another significant patent by Iida is a video system featuring adjustable digital gamma correction for contrast. This system includes a television camera, a digital video signal processor, and a television monitor. The digital video signal processor converts analog video signals into video data and processes it for display. It features a central processing unit that selects different gamma corrections from a read-only memory device, allowing for enhanced video quality.
