  • Patent number: 7704843
    Abstract: In a semiconductor device and a method of manufacturing the same, a conductive structure is formed on an active region defined by a device isolation layer on a semiconductor substrate. The conductive structure includes a gate pattern and source/drain regions adjacent to the gate pattern. A first semiconductor layer is formed on the active region by a selective epitaxial growth (SEG) process. An amorphous layer is formed on the first semiconductor layer. A second semiconductor layer is formed from a portion of the amorphous layer by a solid-phase epitaxy (SPE) process. Elevated structures are formed on the source/drain regions by removing a remaining portion of the amorphous layer from the substrate, so the elevated structure includes the first semiconductor layer and the second semiconductor layer stacked on the first semiconductor layer. The device isolation layer may be prevented from being covered with the elevated structures, to thereby prevent contact failures.

  • Patent number: 7669605
    Abstract: A heated eyelash curler comprising a curling head having a heating element, a cover switch engaged with the heated eyelash curler, and a body enclosing operational components of the heated eyelash curler connected to the curling head. The cover switch turns the heating element “on” after exposing the curling head and turns the heating element “off” after covering the curling head instead of the current practice of manually turning the switch “on” and “off”. The engagement between the parts on the cover switch and the heated eyelash curler attaches the cover switch to the body of the heated eyelash curler. The heating element on the eyelash curler can be conventional or it can adopt wiring in a zigzag configuration housed within a conducting tube coated with a non-sticking material.
