Title: The Innovative Journey of Hiroshi Fujioka

Introduction

Hiroshi Fujioka, an esteemed inventor located in Saitama, Japan, has made significant contributions to the field of semiconductor technology, holding a remarkable portfolio of 10 patents. His inventive spirit has led to groundbreaking advancements that have the potential to reshape various technological landscapes.

Latest Patents

One of Fujioka's latest patents encompasses an InGaAIN-based semiconductor device. This device features transistors engineered using nitride semiconductor layers as channels, which were successfully manufactured through a sputtering method. Notably, the deposition temperature was maintained at less than 600°C, resulting in either a polycrystalline or amorphous InGaAlN layer. The composition ranges defined by the general expression InGaAlN (where x+y+z=1.0) play a crucial role: a transistor exhibiting an ON/OFF ratio of 10 or higher can be achieved when x falls between 0.3 and 1.0, with 0≤z<0.4. Remarkably, even polycrystalline or amorphous films demonstrate electric characteristics comparable to those of single-crystal materials. This breakthrough paves the way for semiconductor devices with drastically fewer constraints on manufacturing conditions and offers an InGaAlN-based nitride semiconductor layer that is both cost-effective and characterized by excellent electric properties as a channel.

Another notable invention is his pen-type controller and tracking system. This device includes a pen portion resembling a traditional pen and a grip portion that intersects the axial direction of the pen. Notably, it features a first light-emitting part positioned at the end of the grip portion, which is closer to the axis of the pen than any other part of the grip. This innovative design enhances usability and precision for users.
