  • Patent number: 6841201
    Abstract: An apparatus and method that generates plasma using a microwave radiation supply. The plasma is used to treat a surface of a workpiece at approximately atmospheric pressure. Plasma excites a working gas to create an excited gaseous species without degradation from undue heat caused by the plasma. The gaseous species exit an outlet of the apparatus to treat the surface of a workpiece when the outlet is juxtaposed with the workpiece.

  • Patent number: 6739046
    Abstract: A method is provided for connecting two conductive surfaces in an electronic circuit package comprising the steps of forming dendrites on selected regions of a first conductive surface, applying a dielectric insulation material over the first conductive surface such that the dendrites are exposed through the insulation material to leave a substantially planar surface of exposed dendrites, and placing a second conductive surface on top of the exposed dendrites. The second conductive surface may be a surface metal, a chip bump array, or a ball grid array. Also claimed is an electronic circuit package incorporating the dendrites used for electrical interconnection and planarization manufactured in accordance with the present invention.

  • Patent number: 6716806
    Abstract: A detergent composition having a plasma-induced, water-soluble coating for controlling solubility, chemical stability and physical properties is disclosed. A process for making such a detergent composition is also disclosed which involves subjecting a detergent material to a plasma glow zone in which an organic hydrophilic monomer is introduced such that it ultimately deposits on the detergent material to form a water-soluble coating. The detergent compositions are particulate or non-particulate and can be used for laundry, dishwashing or other similar application.

  • Patent number: 6660339
    Abstract: The present invention relates to a process, preferably a continuous process, of coating a substrate, which allows water vapor and preferably air permeation, with a hydrophobic coating. The process preferably uses a thin film vacuum condensation step to create a monomer coating which is cured in situ after the coating. The process has the benefit of allowing continuous operation and providing an alternative to existing processes for hydrophobic coating. The substrates are coated such that the water vapour permeation sites are not blocked by the coating to maintain the desired breathability. The static water contact angle on the surface of such substrates is more than 95°.
