  • Patent number: 5910013
    Abstract: A V-H transfer section is formed by the following steps: N+-type impurities are first ion-implanted in such a manner that they spread out into an area larger than a channel of a vertical transfer register. An electrode of the vertical transfer register and electrodes of a horizontal transfer register are then formed. Thereafter, P+-type impurities are implanted into the electrode of the vertical transfer register and the electrodes of the horizontal transfer register in a self-alignment manner.

  • Patent number: 5591660
    Abstract: A solid state imaging device manufacturing process by which a solid state imaging device for a regular image and a solid state imaging device for a mirror image can be manufactured alternatively by a simple operation and a solid state imaging device which allows employment of an existing driving system as a driving system which includes a timing generator are disclosed. In manufacture, a solid state imaging device as an intermediate product is prepared first. The solid state imaging device includes an image section, a horizontal charge transfer section formed from a plurality of transfer electrodes having a fixed number of phases, and a pair of charge detection sections provided at the opposite ends of the horizontal charge transfer section.

  • Patent number: 5060072
    Abstract: A charge-coupled device (CCD) imager is comprised of a CCD image sensor, a horizontal register for delivering an image signal from the CCD image sensor, the horizontal register being formed of an effective bit portion corresponding to the CCD image sensor and first and second dummy bit portions of a predetermined length which are located at both sides of the effective bit portion, and first and second output portions provided in succession to the first and second dummy bit portions to provide a positive image signal and a mirror image signal, wherein the effective bit portion is provided with four bus lines through which a transfer clock is supplied to the horizontal register and the first and second dummy bit portions are provided with two bus lines through which a transfer clock is supplied to the horizontal register. Thus, the CCD imager can be simplified in arrangement and a undesirable charge can be prevented from being mixed into a signal charge.
