Title: Kouta Kameishi: Innovator in Defect Inspection Technology

Introduction

Kouta Kameishi is a notable inventor based in Yokkaichi, Mie, Japan. He has made significant contributions to the field of defect inspection technology, holding 2 patents that showcase his innovative approach to improving inspection processes.

Latest Patents

Kameishi's latest patents include a defect inspection apparatus and a defect inspection method, along with a recording medium. In one embodiment of the defect inspection apparatus, a controller acquires an image of a second actual pattern in a first shot region that corresponds to a design pattern identical to a design pattern corresponding to a first actual pattern. This process is consistent in both the first and second comparison processes. The controller replaces the image of one actual pattern with the image of another to generate a reference image of the first shot region. Subsequently, the controller compares the reference image with the image of the second shot region to perform a defect inspection.

Another embodiment describes an inspection apparatus that includes an irradiation mechanism, an imaging device, a movable mechanism, and a control processor. The irradiation mechanism is designed to irradiate an inspection target with light, while the imaging device captures an image of the inspection target through a lens. The movable mechanism adjusts the angle between the lens and the horizontal plane, ensuring that the sample surface, the principal face of the lens, and the imaging face of the imaging device conform to the Scheimpflug principle. The control processor fine-tunes the sensitivities in the captured image at different levels based on the position in a perpendicular direction to the inspection direction.
