  • METHOD OF METAL PLATING SEMICONDUCTORS
    Publication number: 20140008234
    Abstract: A metal underlayer is selectively plated on semiconductor wafers immediately followed by plating copper on the metal underlayer using a low internal stress copper plating bath. Additional metallization may be done to build up the metal layers using conventional metal plating baths and methods to form current tracks. Formation of metal silicides is avoided. Good adhesion of the metals to the semiconductors is achieved. The metalized semiconductors may be used in the manufacture of photovoltaic devices.

  • Apparatus and method for producing free-standing materials
    Patent number: 8613899
    Abstract: An apparatus includes a manifold with a chamber for mixing multiple reactants. Gases are jetted into the manifold by a plurality of inlet injectors. The inlet injectors are arranged such that the gases passing into the manifold impinge on each other at a common point to form a mixture. The mixture passes through a plurality of holes in one side of the manifold into a deposition chamber where the mixture of gases impinges on additional gases at a common point to provide a reaction resulting in deposition of solid materials in the deposition chamber. The solid materials are free-standing.

  • METHOD OF USING FIBROUS TISSUE SEALANT
    Publication number: 20130337036
    Abstract: Disclosed herein is a fibrous tissue sealant in the form of an anhydrous fibrous sheet comprising a first component which is a fibrous polymer containing electrophilic or nucleophilic groups and a second component capable of crosslinking the first component when the sheet is exposed to an aqueous medium, thereby forming a crosslinked hydrogel that is adhesive to biological tissue. The fibrous tissue sealant may be useful as a general tissue adhesive for medical and veterinary applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures, tissue repair, and to prevent post-surgical adhesions. The fibrous tissue sealant may be particularly suitable for use as a hemostatic sealant to stanch bleeding from surgical or traumatic wounds.
