  • Materials and methods for control of stability and rheological behavior of particulate suspensions
    Publication number: 20040055993
    Abstract: The subject invention relates to a method and materials for the control of the energy barrier to agglomeration with respect to particles. Controlling the energy barrier to agglomeration can, for example, cause the particles to enter suspension and/or depart from suspension, as desired. By fine-tuning the energy barrier, a variety of processes can be enhanced. The subject invention also pertains to the control of the energy barrier between particles and a surface. In a specific embodiment, the subject invention can be utilized for chemical-mechanical polishing (CMP) processes.
