Introduction

Sadao Sasaki is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of mask inspection technology, particularly in the semiconductor industry. His innovative methods have paved the way for advancements in the quality control of lithographic patterns.

Latest Patents

Sasaki holds a patent for a "Method of inspecting masks and apparatus thereof." This method involves several steps, including depositing an electron-emissive layer on the patterned surface of the mask. The electron-emissive layer emits electron beams when irradiated with energy beams. By applying energy beams to the patterned surface from behind, the emitted electron beams are guided to an electron optical system. This process forms an electron beam image of the pattern on a detector, allowing for the comparison of detection signals with reference signals that represent the design shape and size of the pattern. This innovative approach enhances the accuracy of mask inspections.
