    Abstract: An image sensor pixel includes a photodiode region having a first polarity doping type disposed in a semiconductor layer. A pinning surface layer having a second polarity doping type is disposed over the photodiode region in the semiconductor layer. The second polarity is opposite from the first polarity. A first polarity charge layer is disposed proximate to the pinning surface layer over the photodiode region. A contact etch stop layer is disposed over the photodiode region proximate to the first polarity charge layer. The first polarity charge layer is disposed between the pinning surface layer and the contact etch stop layer such that first polarity charge layer cancels out charge having a second polarity that is induced in the contact etch stop layer. A passivation layer is also disposed over the photodiode region between the pinning surface layer and the first polarity charge layer.

    Abstract: Embodiments of a process including depositing a sacrificial layer on the surface of a substrate over a photosensitive region, over the top surface of a transfer gate, and over at least the sidewall of the transfer gate closest to the photosensitive region, the sacrificial layer having a selected thickness. A layer of photoresist is deposited over the sacrificial layer, which is patterned and etched to expose the surface of the substrate over the photosensitive region and at least part of the transfer gate top surface, leaving a sacrificial spacer on the sidewall of the transfer gate closest to the photosensitive region. The substrate is plasma doped to form a pinning layer between the photosensitive region and the surface of the substrate. The spacing between the pinning layer and the sidewall of the transfer gate substantially corresponds to a thickness of the sacrificial spacer. Other embodiments are disclosed and claimed.

    Abstract: Embodiments of the invention describe providing a compact solution to provide high dynamic range imaging (HDRI or simply HDR) for an imaging pixel by utilizing a control node for resetting a floating diffusion node to a reference voltage value and for selectively transferring an image charge from a photosensitive element to a readout node. Embodiments of the invention further describe control node to have to a plurality of different capacitance regions to selectively increase the overall capacitance of the floating diffusion node. This variable capacitance of the floating diffusion node increases the dynamic range of the imaging pixel, thereby providing HDR for the host imaging system, as well as increasing the signal-to-noise ratio (SNR) of the imaging system.

    Abstract: Embodiments of the invention relate to a camera assembly including a rear-facing camera and a front-facing camera operatively coupled together (e.g., bonded, stacked on a common substrate).In some embodiments of the invention, a system having an array of frontside illuminated (FSI) imaging pixels is bonded to a system having an array of backside illuminated (BSI) imaging pixels, creating a camera assembly with a minimal size (e.g., a reduced thickness compared to prior art solutions). An FSI image sensor wafer may be used as a handle wafer for a BSI image sensor wafer when it is thinned, thereby decreasing the thickness of the overall camera module. According to other embodiments of the invention, two package dies, one a BSI image sensor, the other an FSI image sensor, are stacked on a common substrate such as a printed circuit board, and are operatively coupled together via redistribution layers.
