  • Patent number: 5932873
    Abstract: A capacitor coupled bipolar phototransistor having an integrated electronic shutter for reducing the overflow and blooming problems associated with the imaging of strong images. Overflow control and an anti-blooming mechanism are obtained by use of a second emitter (the "shutter") which is used to remove excess image generated charge. This prevents the base-emitter junction potential from becoming forward biased during image integration when the phototransistor is exposed to a strong image. The shutter is biased slightly lower than the first emitter of the phototransistor so that the base-shutter junction is forward biased sooner than the base-emitter junction when the imaging element is exposed to a strong image. The overflow current of the generated holes is then drained to the shutter, rather than into the emitter where it would produce noise on the column sense line.

  • Patent number: 5837574
    Abstract: A capacitor coupled contactless imager structure and method of manufacturing the structure results in a phototransistor that includes an N-type collector region formed in P-type semiconductor material. A P-type base region is formed in the collector region. An n-doped polysilicon emitter contact is formed in contact with the surface of the P-type base region such that an n+ epitaxial region is formed in the base region as the emitter of the imager phototransistor. Silicon dioxide separates the polysilicon emitter contact and exposed surfaces of the base region from a layer of poly2 about 500-600 .ANG. thick that is formed to cover the entire base region.

  • Patent number: 5587596
    Abstract: The size of an active pixel sensor cell is reduced by utilizing a single MOS transistor formed in a well to perform the functions conventionally performed by a photogate/photodiode, a sense transistor, and an access transistor. Light energy striking the well varies the potential of the well which, in turn, varies the threshold voltage of the transistor. As a result, the current sourced by the transistor is proportional to the received light energy.

    Abstract: A capacitor coupled contactless imager structure and a method of manufacturing the structure results in a phototransistor that structure includes an N-type collector region formed in P-type semiconductor material. A P-type base region is formed in the collector region. An n-doped polysilicon emitter contact is formed in contact with the surface of the P-type base region such that an n+ epitaxial region is formed in the base region as the emitter of the phototransistor. Silicon dioxide separates the poly1 emitter content and exposed surfaces at the base region from a layer of poly2 about 3000-4000 .ANG. thick that partially covers the base region; the gates of the CMOS peripheral devices are also poly2. The poly2 over the base region serves as a base coupling capacitor and a row conductor for the imager structure. The thickness of the poly2 capacitor plate allows it to be doped utilizing conventional techniques and silicided to improve the RC constant.
