  • Publication number: 20220139980
    Abstract: An image sensor may include a polydimethylsiloxane (PDMS) layer that is subwavelength, hydrophobic, and/or antireflective. The PDMS layer may be fabricated to include a surface having a plurality of nanostructures (e.g., an array of convex protuberances and/or an array of concave recesses). The nanostructures may be formed through the use of a porous anodic aluminum oxide (AAO) template that uses a plurality of nanopores to form the array of convex protuberances and/or the array of concave recesses. The nanostructures may each have a respective width that is less than the wavelength of incident light that is to be collected by the image sensor to increase light absorption by increasing the angle of incidence for which the image sensor is capable of collecting incident light. This may increase the quantum efficiency of the image sensor and may increase the sensitivity of the image sensor.

  • Patent number: 11282659
    Abstract: Methods for assembling low-profile, singulated keyboards by prefabricating key assemblies onto a chassis strip that is divided into individual key assemblies only after the substrate is affixed to a feature plate of keyboard. For example, a row of key assemblies is fabricated onto a chassis strip. The row corresponds to a partial or complete row of keys of the keyboard. The chassis strip is thereafter affixed to a feature plate in a specific location, thereby aligning each prefabricated key assembly to a precise location on the feature plate. While connected, each prefabricated key assembly is independently affixed to the feature plate. Thereafter, interconnecting portions of the chassis strip between the prefabricated key assemblies are removed, thereby singulating each key assembly.
