摘要： A light source and method for making the same are disclosed. The light source includes a substrate and a light emitting structure that is deposited on the substrate. A barrier divides the light emitting structure into first and second segments that are electrically isolated from one another. A serial connection electrode connects the first segment in series with the second segment. A first blocking diode between the light emitting structure and the substrate prevents current from flowing between the light emitting structure and the substrate when the light emitting structure is emitting light. The barrier extends through the light emitting structure into the first blocking diode.

摘要： A light source and method for making the same are disclosed. The light source includes a plurality of Segmented LEDs connected in parallel to a power bus and a controller. The power bus accepts a variable number of Segmented LEDs. The controller receives AC power and provides a power signal on the power bus. Each Segmented LED is characterized by a driving voltage that is greater than 3 times the driving voltage of a conventional LED fabricated in the same material system as the Segmented LED. The number of Segmented LEDs in the light source is chosen to compensate for variations in the light output of individual Segmented LEDs introduced by the manufacturing process. In another aspect of the invention, the number of Segmented LEDs connected to the power bus can be altered after the light source is assembled.

摘要： Gold is used as a micromask to roughen a gallium nitride (GaN) surface in an LED device. In one example, a mesh of ITO (Indium Tin Oxide) is formed on a GaN layer. The mesh has holes that extend down to the GaN. A layer of silicon dioxide is deposited so that it covers the GaN at the bottoms of the holes. A layer of gold is formed over the oxide. A thermal treatment causes the gold to ball up into small gold features. These gold features are used as a micromask in a subsequent etching step. Areas of the bottoms of the holes that are not covered by a gold feature are etched. Etching occurs through the oxide and down into the GaN. The roughening process involves no silver, and involves no harsh cleaning solvents or processes that might otherwise have been used were the micromask made of silver.

摘要： The present invention provides a highly reliable photodiode, as well as a simple method of fabricating such a photodiode. During fabrication of the photodiode, a grading layer is epitaxially grown on a top surface of an absorption layer, and a blocking layer, for inhibiting current flow, is epitaxially grown on a top surface of the grading layer. The blocking layer is then etched to expose a window region of the top surface of the grading layer. Thus, the etched blocking layer defines an active region of the absorption layer. A window layer is epitaxially regrown on a top surface of the blocking layer and on the window region of the top surface of the grading layer, and is then etched to form a window mesa.
