Filed:

Jan 28, 2005

Appl. No.:

11/044714

Inventors:

Yongsheng Zhao - Monterey Park CA, US

Eugene J. Ruddy - Claremont CA, US

Assignee:

Lumei Optoelectronics Corporation - El Monte CA

International Classification:

H01L 33/00

US Classification:

257 91, 257 98, 257 99, 257100

Abstract:

A high power, high luminous flux light emitting diode (LED) comprises a substrate, a light-emitting structure, a first electrode and a second electrode. The LED has a top surface layout design in which the first electrode has a number of legs extending in one direction, and the second electrode has a number of legs extending in the opposite direction. At least portions of the legs of the first electrode are interspersed with and spaced apart from portions of the legs of the second electrode. This provides a configuration that enhances current spreading along the length of the legs of both electrodes.

International Classification:

H01L 33/00

US Classification:

257 89, 257 88, 257E33047

Abstract:

A three-dimensional LED structure with vertically displaced active-region includes at least two groups of vertically displaced surfaces on a non-planar substrate. The first group of surfaces are separated from the second group of surfaces by a vertical distance in the growth direction of the LED structure. The first group of surfaces are connected to the second group of surfaces by sidewalls, respectively. The sidewalls can be inclined or vertical and have a sufficient height so that a layer such as an n-type layer, an active-region, or a p-type layer in a first LED structure deposited on the first group of surfaces and a corresponding layer such as an n-type layer, an active-region, or a p-type layer in a second LED structure deposited on the second group of surfaces are separated by the sidewalls. The two groups of surfaces may be vertically displaced from each other in certain areas of an LED chip, while merge into an integral surface in other areas. A method for fabricating the three-dimensional LED structure is also provided.

Assignee:

Allergan, Inc. - Irvine CA

International Classification:

A61L 27/00

US Classification:

427 224

Abstract:

A textured breast implant is provided which generally includes a fluid fillable elastomeric shell having a texture defined by struts, for example, hollow struts, defining interconnected open cells. Methods of making the texture include applying a silicone dispersion to a base material and removing the base material from the coating to form a silicone-based structure comprising struts defining interconnected open cells, said struts including internal surfaces defining cavities within the struts. The method may further include the step of contacting the silicone based structure having cavities with a silicone dispersion to cause the silicone to enter and fill the cavities.
