  • Method for sequentially depositing a three-dimensional network
    Patent number: 6277449
    Abstract: A method of producing radio frequency discharge plasma film layers having a three-dimensional functional film network. The plasma film layers include a first layer, comprising a plurality of a first functional group, and a second layer, comprising a plurality of a second functional group. The employment of three-dimensional film networks with desired functional groups located either on the periphery or both the periphery and interstitial spaces of the networks provides means for significantly increasing the surface functional density.
    Type: Grant
    Filed: June 30, 1999
    Date of Patent: August 21, 2001
    Inventors: Omprakash S. Kolluri, Robert G. Johanson
  • Plasma deposited substrate structure
    Patent number: 5962138
    Abstract: A substrate structure having three-dimensional functional film network comprising a plurality of radio frequency discharge plasma film layers. The plasma film layers include a first layer, comprising a plurality of a first functional group, and a second layer, comprising a plurality of a second functional group. The employment of three-imensional film networks with desired functional groups located either on the periphery or both the periphery and interstitial spaces of the networks provides means for significantly increasing the surface functional density.
