    摘要: Embodiments of a method for separating dies from a wafer having first and second sides. The process embodiment includes masking the first side of the wafer, the mask including openings therein to expose parts of the first side substantially aligned with scribe lines of the wafer. The process embodiment also includes etching from the exposed parts of the first side of the wafer until an intermediate position between the first and second sides and sawing the remainder of the wafer, starting from the intermediate position until reaching the second surface.

    摘要: Embodiments of an image sensor pixel that includes a photosensitive element, a floating diffusion region, and a transfer device. The photosensitive element is disposed in a substrate layer for accumulating an image charge in response to light. The floating diffusion region is dispose in the substrate layer to receive the image charge from the photosensitive element. The transfer device is disposed between the photosensitive element and the floating diffusion region to selectively transfer the image charge from the photosensitive element to the floating diffusion region. The transfer device includes a buried channel device including a buried channel gate disposed over a buried channel dopant region. The transfer device also includes a surface channel device including a surface channel gate disposed over a surface channel region. The surface channel device is in series with the buried channel device. The surface channel gate has the opposite polarity of the buried channel gate.

    摘要: An image sensor includes a pixel array, a bit line, a supplemental capacitance node line, and a control circuit. The pixel array includes a plurality of pixel cells each including a floating diffusion (“FD”) node and a photosensitive element coupled to selectively transfer image charge to the FD node. The bit line is coupled to selectively conduct image data output from a first group of the pixel cells. The supplemental capacitance node line is coupled to the FD node of a second group of the pixel cells different from the first group. The control circuit is coupled to the supplemental capacitance node line to selectively increase the potential at the FD node of each of the pixel cells of the second group by selectively asserting a FD boost signal on the supplemental capacitance node line.

In various embodiments, the first and second group of pixel cells may be the same group or a different group of the pixel cells and may add a capacitive boost feature or a multi conversion gain feature.
