Abstract:
The present invention provides composite particles with sufficient strength and hardness and excellent heat resistance, a production process thereof, an aqueous dispersion containing the composite particles, a CMP slurry which is suitable for manufacture of semiconductor devices, and a process for manufacture of semiconductor devices that employs it. The composite particles are prepared by bonding a silane coupling agent and the like, to divinylbenzene polymer particles and then reacting a specific metal alkoxide, colloidal metal oxide and colloidal silica therewith to form a metal compound section and the like, consisting of a metalloxane bond-containing section or metal oxide particle section on at least one of the interior and surface of the polymer particles. The metal compound section, and the like. can also be formed without using a silane coupling agent. The metalloxane bond-containing section, metal oxide particle section and the like, are preferably bonded by chemical bonding and/or non-chemical bonding to the polymer particles via a silane coupling agent and the like, or directly, but they may also be sequestered without bonding. CMP slurries containing these particles can be advantageously utilized for manufacture of various semiconductor devices, and particularly for polishing of wafer surfaces.
Abstract:
A composite material having a structure in which negatively charged colloidal silica having an average particle diameter of not greater than 50 nm and remaining substantially in the form of primary particles is attached to the outer surfaces of negatively charged polymer particles. By using this composite material, there can be obtained molded articles wherein colloidal silica is dispersed in a resin while remaining substantially in the form of primary particles.
