Latest Patents
One of Nojima's latest patents is a method of manufacturing a pillar-type vertical transistor. This innovative approach involves forming a semiconductor pillar with a first conductivity type that protrudes from a semiconductor substrate. A bottom diffusion layer with a second conductivity type is created around the base of the semiconductor pillar. Additionally, a gate insulator film is formed to cover the side surface of the pillar, followed by the formation of a gate electrode. Finally, a top diffusion layer, which includes a semiconductor body formed by epitaxial growth containing an impurity, is established at the top portion of the pillar.
Another notable patent is the method and system of evaluating the distribution of lattice strain on crystal material. This method includes illuminating a sample with a crystal structure using an electron beam in a zone axis direction. It selectively detects certain diffracted waves among multiple diffracted waves produced by the sample. By repeating the illuminating and detecting steps while scanning the sample, a strain distribution image is obtained based on the diffraction intensity at each point.
