Latest Patents

One of Goto's latest patents is an advanced image sensor. This image sensor features a semiconductor substrate of a first conductivity type with a photo-detecting surface. It also includes a semiconductor region of a second conductivity type located beneath the photo-detecting surface, forming a junction with the semiconductor substrate. A dielectric body is integrated within the semiconductor substrate beneath the junction, ensuring that its width does not exceed that of the semiconductor region in the direction parallel to the photo-detecting surface. The dielectric body is polarized due to charges forming a depletion region generated by the semiconductor substrate and the semiconductor region. The width of the dielectric body is approximately equal to that of the inner surface of the depletion region.

Another significant patent by Goto is for a floating gate non-volatile memory. This innovative memory device consists of a substrate with source and drain regions positioned in the surface region of the substrate. These regions are spaced apart, with a channel forming semiconductor region situated between them. A gate insulating film is placed on the channel forming semiconductor region, while a single crystal control region is electrically separated from it. A control gate insulating film is positioned on the single crystal control region, and a floating gate is capacitively coupled with it. Additionally, a chemical-vapor-deposited shield insulating film is formed in a gas atmosphere charge-balanced on the floating gate, with a shield conductive film disposed on top.
