  • Publication number: 20140115836
    Abstract: A slide on zipper device is a fastener that is comprised of two zipper tapes with C-type sliders on the sides without zipper teeth to be slid onto two tracks, which are O-type rails attached to one side of tapes. The sides of the tapes without rails are attached to an article where a fastener is desired. The two zipper tapes with sliders can alternatively be a set of individual blocks with two sliders on the underside to be slid onto a pair of tracks or rails to act as a fastener. This device makes a zipper or fastener easy to change and recyclable.

  • Patent number: 8273633
    Abstract: A method of enhancing dopant activation without suffering additional dopant diffusion, includes forming shallow and lightly-doped source/drain extension regions in a semiconductor substrate, performing a first anneal process on the source/drain extension regions, forming deep and heavily-doped source/drain regions in the substrate adjacent to the source/drain extension regions, and performing a second anneal process on source/drain regions. The first anneal process is a flash anneal process performed for a time of between about 1 millisecond and 3 milliseconds, and the second anneal process is a rapid thermal anneal process performed for a time of between about 1 second and 30 seconds.
