Title: Hirofumi Miyao: Innovator in Electron Beam Lithography

Introduction

Hirofumi Miyao is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electron beam lithography, holding a total of 4 patents. His work focuses on advancing technologies that enhance precision and efficiency in various applications.

Latest Patents

One of Miyao's latest patents is a stage apparatus and electron beam lithography system. This innovative apparatus includes a surface plate and a guide shaft that is fixedly secured to the surface plate. A drive member moves along the guide shaft, and a hydrostatic fluid bearing forms fluid films in the gap between the guide shaft and the drive member. The apparatus also features a positional deviation detection section that detects relative positional deviations affecting the thickness dimensions of the fluid films. Additionally, a state decision section assesses the condition of the apparatus based on the detected positional deviation and outputs relevant information.

Another notable patent is a method and apparatus for preparing a thin-film specimen suitable for transmission electron microscopy (TEM) observation. This invention includes a high-brightness pixel extraction unit that identifies high-brightness pixels forming a specimen image. The decision unit determines whether these pixels form a continuous sequence exceeding a specified number. If so, it sends a signal to an ion gun control unit to halt ion-beam irradiation of the specimen.
