    摘要: A method of fabricating a semiconductor device is described. In this method, a starting substrate of sufficient thickness is selected that has the required defect density levels, which may result in an undesirable doping level. Then a semiconductor layer having a desired doping level is formed on the starting substrate. The resulting semiconductor layer has the required defect density and doping levels for the final product application. After active components, electrical conductors, and any other needed structures are formed on the semiconductor layer, the starting substrate is removed leaving a desired thickness of the semiconductor layer. In a VECSEL application, the active components can be a gain cavity, where the semiconductor layer has the necessary defect density and doping levels to maximize wall plug efficiency (WPE). In one embodiment, the doping of the semiconductor layer is not uniform. For example, a majority of the layer is doped at a low level and the remainder is doped at a much higher level. This can result in improved WPE at particular thicknesses for the higher doped material.

    摘要: Systems, methods and apparatus including computer programs encoded on computer storage media optimize display image quality under a variety of imaging environments. Dynamic frame streams such as those present in video applications may require a higher frame rate to adequately convey motion in the stream. A line multiplying image pipeline may be utilized for dynamic frames, which lowers the resolution of the displayed image. When dithering line multiplied images, a noise signal including asymmetrical high frequency components around zero frequency may be utilized. The display of static frames, such as photographs, may be achieved with acceptable image quality using a relatively lower display frame rate. Such a frame rate may enable the display of a high resolution image. A noise signal tailored for higher resolution, non line multiplied frames, such as a noise signal with symmetric high frequency components around zero frequency may be utilized for static frames.
