Title: Shuzo Oshio: Innovator in Negative Photoresist Technology

Introduction

Shuzo Oshio is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of negative photoresist technology, holding 2 patents that enhance the precision of pattern formation in various applications.

Latest Patents

Oshio's latest patents focus on an apparatus and method for processing negative photoresist. The first patent describes a negative photoresist emulsion that, after exposure to charged particle beams or soft X-ray beams, is transferred to a chamber filled with non-oxidizing gas. This process prevents the curing effect of the photoresist film, allowing for the formation of fine patterns with high precision. The apparatus designed for this method includes a gas chamber connected to an exposure chamber, ensuring that the substrate remains in a non-oxidizing atmosphere before being exposed to the outside environment. The concentration of oxygen in the non-oxidizing gas is crucial, needing to be less than 5%, and preferably less than 1%.
