Title: **Yasuo Iida: A Pioneer in Active Energy Technology**
Introduction
Yasuo Iida, located in Tokyo, Japan, has made significant contributions to the field of active energy technology through his innovative inventions. With a total of four patents to his name, Iida's work reflects a deep commitment to advancing technology, particularly in the areas of irradiating techniques and materials science.
Latest Patents
Among Yasuo Iida's latest patents are groundbreaking advancements that include a method and apparatus for irradiating active energy rays. This invention outlines a sophisticated process in which a target object is transported into an irradiating chamber through a transport inlet. Inside the chamber, the object is irradiated with an active energy beam under an inert gas atmosphere. The system is designed to keep the gas flow resistance at the transport outlet controlled, ensuring efficient irradiation under optimal conditions (X/Y ≥ 1), where X is the gas amount through the inlet and Y is through the outlet. Additionally, Iida developed a positive acting resist material composed of a novolac resin derived from a unique mixture of an alkali-soluble resin and either a quinonediazide compound or poly(2-methylpentene-1-sulfone). This material exhibits a high critical exposure dose, allowing for precise pattern delineation with ionizing radiation and mitigating the issue of film gelling during repeated scanning processes.
