    摘要: One embodiment according to the present disclosure is an imaging apparatus including pixels. The pixel includes a junction type field effect transistor (JFET) provided in a semiconductor substrate. The JFET includes a gate region and a channel region. An orthogonal projection of the gate region onto a plane parallel to a surface of the semiconductor substrate intersects an orthogonal projection of the channel region onto the plane. Each of a source-side portion of the orthogonal projection of the channel region and a drain-side portion of the orthogonal projection of the channel region protrudes out of the orthogonal projection of the gate region.

    摘要: The present invention relates to a semiconductor component (1) having a photosensitive semiconductor layer (2), wherein the photosensitive semiconductor layer (2) is doped with a first doping density (D1) of a first conduction type which brings about an effective conversion of electromagnetic radiation penetrating into the semiconductor layer (2) into electrical charge carriers, having at least two modulation gates (4A, 4B) which are arranged at a mutual spacing and are each formed by a trench gate extending from a surface (3) of the semiconductor layer (2) and perpendicular to this surface (3) into the semiconductor layer (2), and having at least two readout diodes (5A, 5B) arranged at a mutual spacing and near the surface (3) between the two modulation gates (4A, 4B). In order to provide a semiconductor component for distance detection having improved characteristics with regard to sensitivity and resolution, the invention proposes that a separating implant (6) be inserted into the semiconductor layer (2) between the two readout diodes (5A, 5B), said implant having the same conduction type as the semiconductor layer (2), but having a second, higher doping density (D2).

    摘要: An imaging device formed as an active pixel array combining a CMOS fabrication process and a nanowire fabrication process. The pixels in the array may include a single or multiple photogates surrounding the nanowire. The photogates control the potential profile in the nanowire, allowing accumulation of photo-generated charges in the nanowire and transfer of the charges for signal readout. Each pixel may include a readout circuit which may include a reset transistor, charge transfer switch transistor, source follower amplifier, and pixel select transistor. A nanowire is generally structured as a vertical rod on the bulk semiconductor substrate to receive light energy impinging onto the tip of the nanowire. The nanowire may be configured to function as either a photodetector or a waveguide configured to guild the light to the substrate. Light of different wavelengths can be detected using the imaging device.
