Title: Solid-state image pickup element
Inventor: TORIYAMA KEIJI
IPC: H01L27/14
Filed: 1987-07-08
Abstract: PURPOSE:To prevent generation of potential barrier which prevents read operation of signal charge in the section where the conductive region becomes narrow in the side of readout electrode by allowing the signal readout electrode to become longer than the length corresponding to the depth of junction between the second region and first semiconductor layer and to protrude over the second region. CONSTITUTION:The part Y protruding over the impurity region 4 of photodiode of electrode 6 of signal charge readout means is set longer then the length X corresponding to the junction depth of such impurity region. Thereby, since the interval between the end of impurity layer 7 of reverse conductivity type formed on the photodiode surface and the end of impurity region 4 can be set wider than the width corresponding to thickness of such impurity region 4 in the ion implantation process using the signal charge readout electrode 6 as the mask, the width of such impurity region is no longer narrowed at the end of such impurity region. Therefore, the potential barrier which has prevented readout operation of signal charge, which has been a problem in an existing solid-state image pickup element using a buried photodiode as the photodetecting element is no longer generated.

Title: Photosensitive body for positive electrostatic charge
Inventor: FUJIMAKI YOSHIHIDE
IPC: G03G5/14
Filed: 1984-08-17
Abstract: PURPOSE:To form an always satisfactorily visible image by providing a protective layer contg. an electron acceptive material on the single photosensitive layer consisting of a granular carrier generating material having the photosensitivity higher in the negative electrostatic charge stage than in the positive charge stage and carrier transfer material and binder material. CONSTITUTION:A smooth surface characteristic is not obtainable with the photosensitive layer 4 of the single-layer construction alone and therefore toner filming arises in the stage of repetitive use and the image formed is of black spots. Gas adsorption is likely to arise in the stage of corona charge and the white spots are formed on the image as a result of a decrease in the surface resistance when a carrier generating layer 7 is exposed on the surface. The drift of electrons in a surface protective layer 8 consisting merely of a high polymer compd. is difficult if said layer 8 alone is provided. The increase in the residual potential and the consequent fogging of the image are resulted in the repetitive use in such a case. The electron acceptive material is added into the layer 8 in order to solve the above-mentioned problems, by which the drift of the electrons is made smooth and the repetitive characteristics is extremely stabilized.
