Latest Patents

Kodaka's latest patents focus on the design and manufacturing methods of vertical and horizontal type junction FETs. His innovative approach involves a channel-gate structure formed by a double diffusion process. This process allows for the diffusion of different impurities through a single opening in a diffusion mask. For vertical type junction FETs, Kodaka applies this double diffusion process to stacked semiconductor layers with opposite conducting types. This results in a channel region adjacent to the upper semiconductor layer, which serves as the first gate region. A second gate region is then formed adjacent to the channel region, ensuring precise control over the channel width and impurity concentration. Similarly, for horizontal type junction FETs, the process is adapted to a single semiconductor layer, maintaining the same level of precision and control.
