A carrier shape measurement device includes: a stage which supports a carrier which is to be a subject of measurement; and a measurement section which measures a shape of the carrier, and the stage comprises kinematic coupling pins to support the carrier by a kinematic coupling. The timing controller receives input image data at a first frequency substantially equal to a frame rate of an input image. The method also includes buffering incoming data upon the imminence of the handoff to generate buffered incoming data, the incoming data being addressed to the client device. The oxygen content of the top surface of the silicon substrate is higher than other portions of the silicon substrate, but below an amount that would prevent epitaxial growth. When the indicated time has been reached, the data display control apparatus executes instructions to control the display of the multimedia data.
