Introduction

Masaru Irie is a notable inventor based in Mie-ken, Japan, recognized for his significant contributions to technology through his innovative patents. With a total of three patents to his name, Irie has made strides in the field of ultraviolet irradiation and adhesive tape cutting methods.

Latest Patents

One of Irie's latest patents is an ultraviolet irradiation device. This device is designed to apply ultraviolet rays to a surface of a wafer that is joined to a protective tape. The process involves an illumination sensor that moves to a position below an ultraviolet irradiation unit, which contains ultraviolet light-emitting diodes arranged in a one-dimensional array. The sensor measures the ultraviolet intensity corresponding to the surface of the protective tape, allowing for the control of the output voltage of each diode to maintain a uniform accumulated quantity of light in the area where ultraviolet rays are applied. This innovation ensures precision in the application of ultraviolet light.

Another significant patent by Irie is an adhesive tape cutting method and apparatus. In this invention, a strip-shaped supporting adhesive tape is joined to a ring frame and is positioned with a cutter blade that penetrates the adhesive tape. The cutting edge of the blade is brought into contact with the tape joined side of the ring frame, allowing the adhesive tape to be cut along the contour of the ring frame while electric current is fed to both the cutter blade and the ring frame. A sensor monitors the conduction status in real-time, enhancing the efficiency and accuracy of the cutting process.
