Abstract: Provided are a camera tracking system and method and a live video compositing system using the same, which track a main camera with a sub-camera attached to the main camera and thus stably calculate the motion of the main camera even in a dynamic case where most of a static background is occluded by a moving foreground object. The camera tracking system and the live video compositing system can connect feature point tracks that are cut by a foreground object which dynamically moves in an image. Accordingly, the camera tracking system and the live video compositing system can perform the more accurate and quick tracking of a camera even in a case where a foreground object occludes background by dynamically moving.

Abstract: A method of fabricating semiconductor devices, such as GaN LEDs, on insulating substrates, such as sapphire. Semiconductor layers are produced on the insulating substrate using normal semiconductor processing techniques. Trenches that define the boundaries of the individual devices are then formed through the semiconductor layers and into the insulating substrate, beneficially by using inductive coupled plasma reactive ion etching. The trenches are then filled with an easily removed layer. A metal support structure is then formed on the semiconductor layers (such as by plating or by deposition) and the insulating substrate is removed. Electrical contacts, a passivation layer, and metallic pads are then added to the individual devices, and the individual devices are then diced out.

Abstract: Methods of forming electrical interconnects include the steps of forming a first electrically conductive layer on a semiconductor substrate and then forming a first electrically insulating layer on the first electrically conductive layer. A second electrically insulating layer is then formed on the first electrically insulating layer. The second electrically insulating layer is then etched to expose the first electrically insulating layer and then a third electrically insulating layer is formed on the first electrically insulating layer. The first and third electrically insulating layers are then etched to define a contact hole therein which exposes a portion of the first electrically conductive layer. A barrier metal layer is then formed. The barrier metal layer is preferably formed to extend on the third electrically insulating layer and on the exposed portion of the first electrically conductive layer.
