Abstract:
A zoom control mechanism includes a context display for displaying a representation of a data set, a zoom display for displaying a representation of a zoom interval within the data set, a context indicator that indicates a start point or an end point of a zoom interval within a context display, and a zoom indicator, corresponding to the context indicator, that indicates the start point or end point of the zoom interval within the zoom display. The zoom interval is updated according to user selection and movement of the context indicator and the zoom indicator to a new location within the context display and the zoom display, respectively.
Abstract:
Back-illuminated CCD imagers of interline transfer type are made possible by deep, highly doped implant regions which bury the CCDs with respect to the back-illuminated surfaces of the imager substrates. Transfer smear caused by photoconversion in the CCD charge transfer channels must be suppressed in certain of these back-illuminated CCD imagers of interline transfer type, and suitable suppression methods are described.
Abstract:
An imaging array of the charge transfer type having improved sensitivity is disclosed. The array includes a plurality of substantially parallel charge transfer channels with channel stops therebetween which extend a distance into a semiconductor body. At least some of the channel stops have blooming drains therein for the removal of excess photogenerated charge. The improvement comprises potential barrier means which constrain electrical charge generated by absorption of light in the body to flow into the channels while preventing the loss of such charge by direct flow to the blooming drains. Potential barrier means include buried barrier regions extending a further distance into the body from those channel stops having blooming drain regions therein.
Abstract:
An imaging device includes a wafer of single crystal semiconductor material having a first surface with an input surfacing region which extends into the wafer from the first surface and a second surface with a charge storage portion which includes a plurality of discrete charge storing regions which extend into the wafer of the second surface. The wafer includes a potential barrier within the input signal sensing portion for controlling blooming. The wafer is improved by including a passivation region within the input sensing portion for stabilizing the energy level of the conductivity band of the minority carriers at the Fermi energy level of the semiconductor wafer. Additionally, an electrical leakage reduction region extends into the wafer from the second surface. The leakage reduction region is contiguous with each of the discrete charge storage regions.
