Introduction

Hideo Kato is a prominent inventor based in Gifu, Japan, known for his significant contributions to the field of semiconductor materials. With a total of 6 patents to his name, Kato has made remarkable advancements in the production of silicon carbide (SiC) composite materials and single-crystal silicon.

Latest Patents

One of Kato's latest patents is a method for producing SiC/SiC composite material. This innovative process involves impregnating a substrate with a slurry containing particles of a flaky lubricant. The method includes drying out the solvent from the impregnated body, forming an interface layer on the surfaces of the SiC fibers, and transferring the particles of the flaky lubricant to the surfaces of the SiC fibers while stretching the particles. This technique allows for the easy formation of a thin interface layer of the flaky lubricant on the surfaces of the SiC fibers, enhancing the overall quality of the composite material.

Another notable patent is a method for manufacturing single-crystal silicon. This method improves the success rate of multi-pulled single crystal growth using the Czochralski method by utilizing a melt crucible with varying amounts of barium on its inner surface, inversely related to the crucible's diameter. This innovative approach allows for the effective separation of at least one single crystal from the melt by a free span method.
