Abstract: Imaging apparatus (20) includes a photosensitive medium (22) and a bias electrode (32), which is at least partially transparent, overlying the photosensitive medium. An array of pixel circuits (26) is formed on a semiconductor substrate (30). Each pixel circuit includes a pixel electrode (24) coupled to collect the charge carriers from the photosensitive medium; a readout circuit (75) configured to output a signal indicative of a quantity of the charge carriers collected by the pixel electrode; a skimming gate (48) coupled between the pixel electrode and the readout circuit; and a shutter gate (46) coupled in parallel with the skimming gate between a node (74) in the pixel circuit and a sink site. The shutter gate and the skimming gate are opened sequentially in each of a sequence of image frames so as to apply a global shutter to the array and then to read out the collected charge carriers via the skimming gate to the readout circuit.

Abstract: A multispectral sensing device includes a first die, including silicon, which is patterned to define a first array of sensor elements, which output first electrical signals in response to optical radiation that is incident on the device in a band of wavelengths less than 1000 nm that is incident on the front side of the first die. A second die has its first side bonded to the back side of the first die and includes a photosensitive material and is patterned to define a second array of sensor elements, which output second electrical signals in response to the optical radiation that is incident on the device in a second band of wavelengths greater than 1000 nm that passes through the first die and is incident on the first side of the second die. Readout circuitry reads the first electrical signals and the second electrical signals serially out of the device.

Abstract: A sensor module includes a silicon substrate. A set of isolation walls defines, in the silicon substrate, an array of silicon-based image sensor pixels and an array of cavities. An infrared (IR)-sensitive material in the array of cavities forms an array of IR sensor pixels in a same focal plane as the array of silicon-based image sensor pixels.

Abstract: Disclosed herein are cameras and image sensors, and electronic devices containing them, having pixel arrays operable both for obtaining images and detecting flicker in ambient light. For flicker detection, such as prior to image capture, light-generated current from a set of pixels of the pixel array is received at a transimpedance amplifier (TIA) that is formed in a common semiconductor substrate with the pixel array. An output signal of the TIA is digitized and signal processed to detect the flicker in the ambient light. Also disclosed are image sensors having pixel arrays with an embedded modulated light source. The modulated light source may be used for proximity detection, either by time-of-flight or intensity variation of reflected light.

Abstract: An image sensor includes a semiconductor substrate. The semiconductor substrate includes a set of one or more substrate portions. Each substrate portion of the set of one or more substrate portions is electrically isolated from other substrate portions of the set of substrate portions. The image sensor further includes a set of photodiodes, a set of charge storage nodes, a set of charge transfer gates, and a control circuit. Each charge transfer gate of the set of charge transfer gates is disposed on and biased by a different substrate portion of the set of substrate portions. Each charge transfer gate of the set of charge transfer gates is operable to selectively connect a respective photodiode of the set of photodiodes to the charge storage node. The control circuit is operable to dynamically bias each substrate portion of the set of substrate portions independently of each other substrate portion of the set of substrate portions.

Abstract: A sensor stack is described. The sensor stack includes first and second electromagnetic radiation sensors. The first electromagnetic radiation sensor has a high quantum efficiency for converting a first range of electromagnetic radiation wavelengths into a first set of electrical signals. The second electromagnetic radiation sensor is positioned in a field of view of the first electromagnetic radiation sensor and has a high quantum efficiency for converting a second range of electromagnetic radiation wavelengths into a second set of electrical signals and a low quantum efficiency for converting the first range of electromagnetic radiation wavelengths into the second set of electrical signals. The first range of wavelengths does not overlap the second range of wavelengths, and the second electromagnetic radiation sensor is at least partially transmissive to the first range of electromagnetic radiation wavelengths.

Abstract: Disclosed herein are global shutter image sensors and methods of operating such image sensors. An image sensor includes a semiconductor wafer having a light receiving surface opposite an electrical connection surface; an oxide extending from the light receiving surface toward the electrical connection surface and at least partially surrounding a pixel region; a photodiode disposed within the pixel region; and a set of storage nodes disposed under the photodiode, between the photodiode and the electrical connection surface. The set of storage nodes comprises a first storage node and a second storage node. The storage nodes may be disposed vertically beneath the photodiode, or side by side.
