  • Ion energy attenuation method by determining the required number of ion collisions
    Patent number: 6013984
    Abstract: A method and an apparatus for controlling the location where the formation of a contamination layer occurs in a plasma processing system is disclosed. The control is accomplished by reducing the released ion's kinetic energy to approximately at most the surface potential of the selected surface to which it is to combine within the desired location.

  • Process for rapidly immobilizing paper coating compositions
    Patent number: 5093159
    Abstract: Rapidly immobilizing paper coating compositions may be prepared by formulating an aqueous coating composition comprising a cationic starch, pigment and sufficient base to obtain a pH above the pK of the starch derivative so that the starch is no longer cationic; coating the paper substrate; and lowering the pH of the coating such that the starch becomes cationic.
