  • Publication number: 20220052102
    Abstract: Photosensitive devices and associated methods are provided. In one aspect, for example, a photosensitive imager device can include a semiconductor substrate having multiple doped regions forming at least one junction, a textured region coupled to the semiconductor substrate and positioned to interact with electromagnetic radiation, and an electrical transfer element coupled to the semiconductor substrate and operable to transfer an electrical signal from the at least one junction. In one aspect, the textured region is operable to facilitate generation of an electrical signal from the detection of infrared electromagnetic radiation. In another aspect, interacting with electromagnetic radiation further includes increasing the semiconductor substrate's effective absorption wavelength as compared to a semiconductor substrate lacking a textured region.

  • Publication number: 20200105822
    Abstract: Backside illuminated photosensitive devices and associated methods are provided. In one aspect, for example, a backside-illuminated photosensitive imager device can include a semiconductor substrate having multiple doped regions forming a least one junction, a textured region coupled to the semiconductor substrate and positioned to interact with electromagnetic radiation where the textured region includes surface features sized and positioned to facilitate tuning to a preselected wavelength of light, and a dielectric region positioned between the textured region and the at least one junction. The dielectric region is positioned to isolate the at least one junction from the textured region, and the semiconductor substrate and the textured region are positioned such that incoming electromagnetic radiation passes through the semiconductor substrate before contacting the textured region.

  • Publication number: 20180216928
    Abstract: Stacked imager devices that can determine distance and generate three dimensional representations of a subject and associated methods are provided. In one aspect, an imaging system can include a first imager array having a first light incident surface and a second imager array having a second light incident surface. The second imager array can be coupled to the first imager array at a surface that is opposite the first light incident surface, with the second light incident surface being oriented toward the first imager array and at least substantially uniformly spaced. The system can also include a system lens positioned to direct incident light along an optical pathway onto the first light incident surface. The first imager array is operable to detect a first portion of the light passing along the optical pathway and to pass through a second portion of the light, where the second imager array is operable to detect at least a part of the second portion of light.
