    Abstract: Imaging systems may include fluidic color filter elements to increase the flexibility of the system. An imaging system may include a number of fluid reservoirs with different color filter element fluids. The imaging sensor may include a number of separated color filter chambers. Fluids from the fluid reservoirs may be directed to specific color filter chambers as desired, with the option to change the color filter fluid in a chamber to a different color filer fluid at any time. To move the fluids to and from the fluid reservoirs to the color filter chambers, electrowetting may be used. The color filter chambers may be interposed between a ground electrode and a number of patterned electrodes. Voltages may be applied to the patterned electrodes to move the fluid to desired positions within the chambers.

    Abstract: An image sensor with an array of pixels is provided. The array may include a semiconductor substrate having opposing first and second sides. A first photodiode region may be implanted in the semiconductor substrate through the first side. A second photodiode region may be implanted in the semiconductor substrate through the second side. The second photodiode region may be implanted to overlap with the first photodiode region in the semiconductor substrate to form a continuous photodiode region that extends from the first side to the second side of the substrate. The continuous region may generate charge in response to image light. The continuous region may belong to a single pixel that generates an image signal from the charge. The image signal may be conveyed to readout circuitry via metallization layers formed over the substrate. The first and second photodiode regions may be thermally activated prior to forming the metallization layers.

    Abstract: An imaging system may include several different types of pixels that are each configured to detect different characteristics of light received at the imaging system. An imaging system may include image sensing pixels that detect the wavelength and intensity of the light, direction sensing pixels that detect the directionality of the light, polarization sensing pixels that detect a polarization state of the light, and diffractive wavelength separation pixels that detect multiple different wavelength components of the light. One or more pixels of the different types may be arranged in a pixel cluster. A pixel cluster that includes different pixel types may detect spatially correlated information for multiple characteristics of the light. Multiple pixel clusters may he arranged in a pixel array that generates an image based on spatially correlated information for the different characteristics of the light.

    Abstract: An imaging system may be used to image a fluid sample containing particles. The imaging system may include a fluid channel that receives the fluid sample and a reactive agent that selectively attaches to target particles in the fluid sample. An activation mechanism may be operated to trigger a chemical reaction between the fluid sample and the reactive agent. The imaging system may include an image sensor integrated circuit and image sensor pixels to capture a detectable effect of the chemical reaction. The image sensor integrated circuit may be synchronized to the activation mechanism such that it captures an image of the fluid sample after the chemical reaction is triggered by the activation mechanism.

    Abstract: A high dynamic range image sensor may include a plurality of pixel groups. One or more pixel groups may include attenuated pixels in addition to unattenuated pixels. The unattenuated pixels may include a photosensitive area, a color filter element and a microlens of a first size. Each attenuated pixel may include a photosensitive area, a color filter element, a neutral density filter, and a microlens of a second size that is smaller than the first size. The color filter elements for each pixel in a given pixel group may be the same color. The neutral density filter may attenuate light for the attenuated pixels, increasing dynamic range of the image sensor. The microlenses of varying sizes may redirect light from attenuated pixels towards unattenuated pixels, further increasing the dynamic range.

    Abstract: An image sensor may include phase detection pixels that gather phase detection data. The phase detection pixels may be formed in phase detection pixel groups with two or more phase detection pixels covered by a single microlens. Each phase detection pixel may have an asymmetric angular response to incident light. Phase detection pixels may be covered by diffractive lenses. A diffractive lens may cover a phase detection pixel pair to improve angular separation between the pixels. A diffractive lens may partially cover a phase detection pixel in a phase detection pixel pair to shift the angular response and account for an off-axis chief ray angle of the phase detection pixel pair.

    Abstract: A semiconductor wafer has a plurality of non-rectangular semiconductor die with an image sensor region. The non-rectangular semiconductor die has a circular, elliptical, and shape with non-linear side edges form factor. The semiconductor wafer is singulated with plasma etching to separate the non-rectangular semiconductor die. A curved surface is formed in the image sensor region of the non-rectangular semiconductor die. The non-rectangular form factor effectively removes a portion of the base substrate material in a peripheral region of the semiconductor die to reduce stress concentration areas and neutralize buckling in the curved surface of the image sensor region. A plurality of openings or perforations can be formed in a peripheral region of a rectangular or non-rectangular semiconductor die to reduce stress concentration areas and neutralize buckling. A second semiconductor die can be formed in an area of the semiconductor wafer between the non-rectangular semiconductor die.

    Abstract: Color filters may affect imaging performance attributes such as low light sensitivity, color accuracy, and modulation transfer function (MTF). In an image pixel array, these factors are influenced by both the spectral absorption and pattern of the color filter elements. Different portions of an image sensor may prioritize different imaging performance attributes. Accordingly, in certain applications it may be beneficial for color filter characteristics to vary across an image sensor. Different color filters of the same color may have different structures to optimize imaging performance across the image sensor.
