Abstract: An apparatus and method for processing semiconductor substrates provides a substrate stage being a rotatable disc with a solid surface and a terraced edge with upper, intermediate and lower portions of increasing diameter. A hollow edge ring rests on the intermediate edge portion and a substrate disposed on the rotatable disc is lifted and transported by robot blades positioned beneath the edge ring and which lift the edge ring which holds the substrate around its edges. The rotatable disc and edge ring find application in MOCVD and other semiconductor manufacturing tools.

Abstract: Multiple display device taskbars are described. A system is described that includes at least one or more modules implemented at least partially in hardware. The one or more modules are operable to configure a display environment of a computing device to display a first taskbar for display on a first display device of the display environment, the first taskbar configured to include a representation of a plurality of applications that are executed by the computing device. The one or more modules are also operable to configure a second taskbar for display on a second display device of the display environment, the second taskbar configured to include a representation of at least one application that corresponds to a user interface configured for output on the second display device and does not include a representation of another application that corresponds to a user interface configured for output on the first display device.
