Title: Innovations of Yoshihiro Shintani

Introduction

Yoshihiro Shintani is a notable inventor based in Tokushima, Japan. He has made significant contributions to the field of materials science, particularly in the production of diamond films. With a total of three patents to his name, Shintani's work focuses on innovative processes that enhance the quality and efficiency of diamond film production.

Latest Patents

One of his latest patents is a process for producing single crystal diamond film. This process economically produces single crystal diamond film with a large surface area through gas-phase synthesis. It involves depositing a platinum film or platinum alloy film containing more than 50 atomic % of platinum on a basal substrate with (111) or (001) surface while maintaining the substrate temperature at 300°C or above. The platinum or platinum alloy film is then annealed at 1000°C or above, followed by gas-phase synthesis of diamond using the platinum or platinum alloy film as the substrate.

Another significant patent is related to methods for manufacturing monocrystalline diamond films. This method allows for the growth of monocrystalline diamond films by chemical vapor deposition on a large area at a low cost. The substrate materials used can be bulk single crystals of platinum or its alloys, or thin films of those materials deposited on suitable supporting materials. The surfaces of these substrates must be either (111) or (001), or must have domain structures consisting of (111) or (001) crystal surfaces. To increase the nucleation density of diamond, the substrate surface can be scratched or carbon implanted, allowing for the growth of high-quality monocrystalline diamond films.
