Introduction

Masaki Hosoda is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of electron beam technology, holding a total of 6 patents. His work focuses on enhancing the precision and efficiency of electron beam writing systems.

Latest Patents

Among his latest innovations is the "Electron beam writing system and electron beam writing method." This technology enables highly accurate deflection correction of a minute field used in electron beam writing systems. The system incorporates a function to move an electron beam through high-speed deflection scanning, allowing for the repeated formation of a cyclic patterned electron beam. Additionally, it features a low-speed deflection scanning function that synchronizes with the repetition cycle to move the patterned electron beam on cyclic correction marks. This method detects reflected or secondary electrons emitted from the correction marks to correct the position or deflection amount of the electron beam based on the detection results.

Another notable patent is the "Method and apparatus for applying charged particle beam." This technology facilitates positional adjustment of a crossover in charged particle beam applying apparatuses, such as electron beam lithography systems. It includes a front focal plane of a condenser lens with a sharp end face that regulates the height of the crossover on a beam axis. This allows for continuous monitoring of the electron beam shape, ensuring consistent performance even with changes in the crossover height or lens resistance.
