Latest Patents

Masaaki Isobe holds a patent for a CCD imager. This invention includes a large number of light receiving sections, each featuring a semiconductor surface region of a second conductivity type, a first semiconductor region of a first conductivity type, a semiconductor region of the second conductivity type, and a second semiconductor region of the first conductivity type, arranged vertically. The second semiconductor region is designed with a dual structure comprising a low concentration semiconductor region and a high concentration semiconductor region. This dual structure allows for shuttering at a lower voltage, as the potential barrier along the depth of the light receiving section is unaffected by the amount of stored charges. Additionally, the high concentration semiconductor region suppresses the spreading of the depletion layer at the junction.
