Title: Takuma Nakano: Innovator in Semiconductor Technology

Introduction

Takuma Nakano is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of six patents. His work focuses on advancing the capabilities and efficiency of semiconductor devices.

Latest Patents

One of Nakano's latest patents is for a nitride semiconductor device. This device is formed through a process that begins with the deposition of a silicon nitride (SiN) film on a semiconductor layer using the lower pressure chemical vapor deposition (LPCVD) technique. The process involves creating an opening in the SiN film for an ohmic electrode and preparing a photoresist that fully covers this opening. The semiconductor layer is then exposed to chlorine (Cl) plasma, which etches the layer to form a recess. Metals for the ohmic electrode are filled within this recess and the surrounding area of the SiN film, followed by alloying the metals at a temperature lower than the deposition temperature of the SiN film.

Another notable patent by Nakano is for a semiconductor device that includes a field plate on an insulating film covering a transistor. This field plate is electrically coupled to the gate of the transistor via the insulating film. The device features a silicon nitride protective film, a silicon oxide base film, and a MIM capacitor that consists of a first electrode, a dielectric film, and a second electrode stacked in order. The MIM capacitor is formed by performing wet etching on the silicon oxide base film after the dielectric film is created.
