  • Patent number: 11804574
    Abstract: Light Emitting Diodes (LEDs) made with GaN and related materials are used to realize high efficiency devices which emit visible radiation. These GaN-based LEDs consists of a multi-layer structure which include p-type electron confinement layers, and p-type current spreading and ohmic contacts layers located above the active region. The alignment of the etched features which penetrate near or through the active region and the ohmic contact is critical and is currently a technological challenge in the fabrication process. Any errors in this alignment and successive layers will short across the active layers of the device and result in reduced yield of functional devices. The invention described herein provides a method and apparatus to realize the successful alignment and streamlined fabrication of high-density LED array devices. The result is a higher pixel density GaN-based LED device with higher current handling capability resulting in a brighter device of the same area.

  • Patent number: 11333896
    Abstract: The systems and methods discussed herein are for the fabrication of diffraction gratings, such as those gratings used in waveguide combiners. The waveguide combiners discussed herein are fabricated using nanoimprint lithography (NIL) of high-index and low-index materials in combination with and directional etching high-index and low-index materials. The waveguide combiners can be additionally or alternatively formed by the directional etching of transparent substrates. The waveguide combiners that include diffraction gratings discussed herein can be formed directly on permanent transparent substrates. In other examples, the diffraction gratings can be formed on temporary substrates and transferred to a permanent, transparent substrate.
