    摘要: An apparatus and a method for protecting charge storage elements from photo-induced currents in silicon integrated circuits are provided. In order to protect against photo-induced currents that are generated outside the storage node circuits themselves, an n-well guard ring is placed as closely as possible to the transistors and other elements in the storage node circuits. As a result there is a minimum of exposed silicon area in which light can produce current in areas next to the storage node circuits, and the n-well guard ring captures photo-induced currents that are generated outside the storage node circuits. In order to protect against the photo-induced currents that are generated inside the storage node circuits, an aluminum interconnect layer is placed on top of the storage node circuit, separated by an insulating layer of silicon dioxide. This creates a shield against the light and protects the storage node circuit by reflecting light away.

    摘要: A semiconductor isolation structure. The semiconductor isolation structure includes a substrate. A first device and a second device are formed within the substrate. An isolation region is formed within the substrate between the first device and the second device. The isolation region includes a deep region which extends into the substrate. The deep region includes a deep region cross-sectional area. A shallow region extends to the surface of the substrate. The shallow region includes a shallow region cross-sectional area. The deep region cross-sectional area is greater than the shallow region cross-sectional area. For an alternate embodiment, the deep region includes an oxide and the shallow region includes a protective wall. The protective wall can be formed from an oxide and a nitride.

    摘要: A color detection active pixel sensor. The color detection active pixel sensor includes a substrate. A diode is electrically connected to a first doped region of the substrate. The diode conducts charge when the diode receives photons having a first range of wavelengths. The substrate includes a second doped region. The second doped region conducts charge when receiving photons having a second range of wavelengths. The photons having the second range of wavelengths passing through the diode substantially undetected by the diode. The substrate can include a doped well within the substrate. The doped well conducts charge when receiving photons having a third range of wavelengths. The photons having the third range of wavelengths pass through the diode substantially undetected by the diode.
