    Abstract: Memory devices include a stack of interleaved conductive patterns and insulating patterns disposed on a substrate. A semiconductor pattern passes through the stack of conductive patterns and insulating patterns to contact the substrate, the semiconductor pattern having a graded grain size distribution wherein a mean grain size in a first portion of the semiconductor pattern proximate the substrate is less than a mean grain size in a second portion of the semiconductor pattern further removed from the substrate. The graded grain size distribution may be achieved, for example, by partial laser annealing.

  • Publication number: 20110186072
    Abstract: An eyelash groomer having multiple functions on a function head portion of the groomer. The number of functions depend upon the number of function head pieces. Each function head pieces is recommended to have a plurality of small bridges protruding perpendicularly from its respective bases to cage a heating element accessible to each function head piece of the function head of the eyelash groomer. The bridges also prevent the skin from directly contacting the heating element but allow the eyelashes direct contact for optimum curling. The bridges also serve as a guide for the eyelashes because the eyelashes enter at the intervals or spaces between the bridges. The heating element run horizontally beneath each function head piece. A heating mechanism heats the heating element and a protection case houses the components of the heating mechanism and serves as a handle for the eyelash groomer.
