Title: The Innovative Contributions of Takashi Iwasa
Introduction
Takashi Iwasa is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of electronic elements, particularly in the development of manufacturing methods for field emission cathodes. With a total of 8 patents to his name, Iwasa's work has had a considerable impact on the industry.
Latest Patents
One of Iwasa's latest patents focuses on a manufacturing method of a field emission cathode. This method aims to provide a manufacturing process that does not adversely affect element characteristics during ion beam etching. The process involves forming a sacrificial layer made of thermosetting resin on a gate electrode layer. An opening section is created in both the sacrificial layer and the gate electrode layer by irradiating a focused ion beam. Subsequently, a hole section is formed by etching the insulating layer using the sacrificial layer and the gate electrode layer as a mask. An emitter electrode is then formed in the hole section, and the emitter material on the sacrificial layer is removed along with the sacrificial layer on the gate electrode layer. Another notable patent involves an electronic element formed of a deposited film containing cesium (Cs), featuring a plurality of conical projections on its surface. These projections, made of cesium oxide, have an average height ranging from 10 nm to 500 nm. This electronic element serves as a cold cathode element, demonstrating high practicality and the ability to emit electrons even with a low voltage applied.
