  • Publication number: 20170345972
    Abstract: Light emitting diodes and associated methods of manufacturing are disclosed herein. In one embodiment, a light emitting diode (LED) includes a substrate, a semiconductor material carried by the substrate, and an active region proximate to the semiconductor material. The semiconductor material has a first surface proximate to the substrate and a second surface opposite the first surface. The second surface of the semiconductor material is generally non-planar, and the active region generally conforms to the non-planar second surface of the semiconductor material.
    Type: Application

  • Patent number: 9057514
    Abstract: A solid state lighting (SSL) device with a solid state emitter (SSE) being partially exposed in a channel loop, and methods of making and using such SSLs. The SSE can have thermally conductive projections such as fins, posts, or other structures configured to transfer heat into a fluid medium, such as a liquid coolant in the channel loop. The channel loop can include an upward channel in which the SSE is exposed to warm the coolant in the upward channel, and a downward channel through which coolant moves after being cooled by a cooling structure. The coolant in the channel loop can naturally circulate due to the heat from the SSE.

  • Patent number: 9041005
    Abstract: Solid state lighting (“SSL”) devices with cellular arrays and associated methods of manufacturing are disclosed herein. In one embodiment, a light emitting diode includes a semiconductor material having a first surface and a second surface opposite the first surface. The semiconductor material has an aperture extending into the semiconductor material from the first surface. The light emitting diode also includes an active region in direct contact with the semiconductor material, and at least a portion of the active region is in the aperture of the semiconductor material.

  • Patent number: 8796665
    Abstract: Solid state radiation transducer (SSRT) assemblies and method for making SSRT assemblies. In one embodiment, a SSRT assembly comprises a first substrate having an epitaxial growth material and a radiation transducer on the first substrate. The radiation transducer can have a first semiconductor material grown on the first substrate, a second semiconductor material, and an active region between the first and second semiconductor materials. The SSRT can also have a first contact electrically coupled to the first semiconductor material and a second contact electrically coupled to the second semiconductor material. The first substrate has an opening through which radiation can pass to and/or from the first semiconductor material.

  • Publication number: 20130040245
    Abstract: A method of processing a substrate includes forming first photoresist on a substrate. A portion of the first photoresist is selectively exposed to actinic energy and then the first photoresist is negative tone developed to remove an unexposed portion of the first photoresist. Second photoresist is formed on the substrate over the developed first photoresist. A portion of the second photoresist is selectively exposed to actinic energy and then the second photoresist is negative tone developed to remove an unexposed portion of the second photoresist and form a pattern on the substrate which comprises the developed first photoresist and the developed second photoresist. Other implementations are disclosed.
