    摘要: The invention is directed to an image sensor with enhanced blue response and limited cross-talk. The image sensor is made of a photodiode layer. Disposed on one side of the photodiode layer is a substrate layer made out of an oppositely charged semiconductor material. The substrate layer is further defined by two different sub-layers, where the doping densities of the sub-layers differ. This difference in doping creates a deep electric field that inhibits carriers from moving to another sensor. Additionally, the potential of the deep electric field directs these carriers back to the N-P junction formed by the substrate layer and the photodiode layer. Working in conjunction with this, a shallow implant layer is disposed on the opposite side of the photodiode layer. The shallow implant layer creates an electric field between the photodiode layer and the shallow implant layer, directing carriers to the photodiode layer. As such, carriers generated in the shallow areas of the image sensor are discouraged from surface recombination effects.

    摘要: A drive transistor for a high resolution ink jet printhead having a pocket implant in the gate region of the device. The pocket implant enables a reduced source to drain spacing without loss of breakdown voltage. Accordingly, the size of the transistor may be reduced. Alternatively, this device is suitable for addressing 1200 spi resolution printheads. In one embodiment, the pocket implant extends about 1 .mu.m beyond the gate region towards the drain region. Both embodiments produce a graded drift region.
