20080315220 | High Light Efficiency Solid-State Light Emitting Structure And Methods To Manufacturing The Same - In one embodiment of an epitaxial LED device, a buffer layer (e.g. dielectric layer) between the current spreading layer and the substitute substrate comprises a plurality of vias and has a refractive index that is below that of the current spreading layer. A reflective metal layer between the buffer layer and the substitute substrate is connected to the current spreading layer through the vias in the buffer layer. The buffer layer separates the current spreading layer from the reflective metal layer. In yet another embodiment, stress management is provided by causing or preserving stress, such as compressive stress, in the LED so that stress in the LED is reduced when it experiences thermal cycles. In one implementation of this embodiment, a layer is attached to the LED and reflective metal layer, and causes or preserves stress in the LED along one or more directions parallel to an interface between the LED epitaxial layers so that stress in the LED is reduced in said one or more directions when temperature of the structure is increased. | 12-25-2008 |
20100032699 | System for High Efficiency Solid-State Light Emissions and Method of Manufacture - In one embodiment of the invention, a bonding material is used to bond a substitute substrate to the LED, wherein the bonding material does not including gold or tin. The bonding material preferably includes gallium (Ga), such as a combination of Ga and Al or Cu. This bonding material has high thermal conductivity, high strength, high temperature stability and is low cost. In another embodiment of the invention, the substitute substrate is first thinned before it is bonded to the LED structure, so that the substitute substrate is flexible and conforms to the shape of the LED structure. In yet another embodiment of the invention, an apparatus is used for bonding a substitute substrate to a LED which comprises a plurality of semiconductor epitaxial layers, said semiconductor epitaxial layers having been grown on the growth substrate so that said semiconductor epitaxial layers are curved in shape. The apparatus comprises a conduit for evacuating a region near the substitute substrate on a side of the substitute substrate that is opposite to that of said semiconductor epitaxial layers. Gas pressure is applied on the semiconductor epitaxial layers, and the substitute substrate conforms to the shape of said semiconductor epitaxial layers as a result of pressure applied. A bonding material is used for bonding said substitute substrate to the semiconductor epitaxial layers. | 02-11-2010 |

20160138944 | Proximity Sensor - A proximity sensor for an electronic device comprises a proximity module, a lens and an optical module secured in an air gap therebetween. The proximity module has an emitter and a detector and is configured to generate a signal that is a function of light emitted by the emitter, and light detected by the detector, some portion of the detected light having been reflected by a target external to the electronic device. A transmissive-reflective surface of the optical module is aligned with the emitter field of view (FOV) and the detector FOV. The optical module guides emitted light through a transmissive portion of the lens to the exterior of the electronic device, and guides target-reflected light collected by the transmissive portion to the detector. The emitter FOV and the detector FOV are substantially aligned with one another. | 05-19-2016 |
