Title: **Hiroshi Amano: Pioneer in Semiconductor Innovation**
Introduction
Hiroshi Amano is a renowned inventor based in Aichi, Japan, celebrated for his significant contributions to the field of semiconductor technology. With a total of 13 patents to his name, Amano has played a pivotal role in advancing the development of group III nitride semiconductors.
Latest Patents
Among his latest patents is a manufacturing method for a group III nitride semiconductor substrate. This innovative method includes several critical steps: the first involves forming a second group III nitride semiconductor layer on a substrate; the second step integrates the creation of a protective layer on this layer; the third step focuses on selectively forming pits on dislocation areas of the semiconductor layer using gas-phase etching; and finally, the fourth step involves the formation of a third group III nitride semiconductor layer to ensure the preservation of these pits.
Another notable patent describes a method for producing a template for epitaxial growth. This process uses a sapphire (0001) substrate that undergoes recess and protrusion formation to create a flat plane-view pattern. An initial-stage AlN layer is then grown on this substrate using C+ orientation control, ensuring that recesses remain partially open while allowing for a subsequent AlGaN layer to be epitaxially grown, resulting in a template with a fine and flat surface.
