  • Processes for depositing silicon-containing films using halidosilane compounds and compositions
    Patent number: 11913112
    Abstract: Processes for depositing silicon-containing films (e.g., silicon, amorphous silicon, silicon oxide, silicon nitride, silicon carbide, silicon oxynitride, silicon carbonitride, doped silicon films, and metal-doped silicon nitride films) are performed using halidosilane precursors. Examples of halidosilane precursor compounds described herein, include, but are not limited to, monochlorodisilane (MCDS), monobromodisilane (MBDS), monoiododisilane (MIDS), monochlorotrisilane (MCTS), and monobromotrisilane (MBTS), monoiodotrisilane (MITS).

  • Process for preparing novel composite imaging materials and novel composite imaging materials prepared by the process
    Publication number: 20090011352
    Abstract: The invention relates to a versatile process for preparing composite powders that can be used as novel electrostatic charge control agents, dry or liquid toners, and specialty imaging materials. The process involves impregnating specific sized, porous, inorganic core particles with chemical compositions that include one or more polymers or waxes and at least one additional chemical chosen from dyes, pigments, carbon black, inorganic chemicals or organic chemicals. The impregnated core may optionally be coated with additional components to produce a core/shell structure.
