Title: Eiji Tai: Innovator in Semiconductor Technology

Introduction

Eiji Tai is a prominent inventor based in Yasu-gun, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on innovative methods for forming electrodes and field effect transistors.

Latest Patents

Eiji Tai's latest patents include an electrode forming method and a field effect transistor. The electrode forming method involves creating a gate electrode through a series of precise steps. A first resist layer with a first opening is applied to a semiconductor substrate, followed by a second resist layer with a larger opening. A first conductor layer made of a high-melting-point metal is then formed, succeeded by a second conductor layer of low-resistance metal. The first conductor layer is etched away within the second opening, and the resist layers are subsequently removed through a lift-off process and ashing.

His second patent focuses on a fine electrode-forming masking member designed to create fine gate electrodes, which can reduce the gate length of a field effect transistor. This method includes forming a first masking member with penetrating portions that align with the fine gate electrodes on a semiconductor substrate using a photosensitive resin. The first masking member is heated to allow parts in contact with the substrate to flow, forming extension portions that decrease the widths of the penetrating portions. Gate electrodes are then formed on the exposed regions of the semiconductor substrate.
