  • Patent number: 6628333
    Abstract: In an illustrative embodiment, an instant camera is provided which includes an imager for receiving an image of an object to be photographed. The imager outputs a signal corresponding to the received image, and a memory device stores the signal. A printer prints instant film photographs corresponding to received or stored images, and has the capability to print at least one image on a single piece of instant film. A preview unit has at least one display for displaying an image corresponding to a received or stored image. A controller, in communication with the imager, the memory device, the printer, and the preview unit, controls the transfer of the signal from the imager to the memory device, from the memory device to the printer, and from the memory device to the preview unit.

  • Patent number: 6524935
    Abstract: A method for forming strained Si or SiGe on relaxed SiGe on insulator (SGOI) is described incorporating growing epitaxial Si1−yGey layers on a semiconductor substrate, implanting hydrogen into a selected Si1−yGey layer to form a hydrogen-rich defective layer, smoothing surfaces by Chemo-Mechanical Polishing, bonding two substrates together via thermal treatments and separating two substrates at the hydrogen-rich defective layer. The separated substrates may have its upper surface smoothed by CMP for epitaxial deposition of relaxed Si1−yGey, and strained Si1−yGey depending upon composition, strained Si, strained SiC, strained Ge, strained GeC, and strained Si1−yGeyC.
