    Abstract: The invention provides a composition comprising core-shell nanoparticles, the nanoparticles comprising (a) cationic core material comprising polymer; and (b) a shell material comprising silica. Preferred core materials comprise diblock copolymer micelles comprising one block of dialkylaminoethyl methacrylate units which are partially or fully quaternised and one block of dialkylaminoethyl methacrylate units that remain non-quaternised. The invention also provides a method for the preparation of the said composition, the method involving (a) preparing a cationic core material comprising polymer; and (b) coating the core material with a shell comprising silica by treating the polymer with a silica precursor under ambient conditions. The invention also envisages a composition comprising core-shell nanoparticles which is adapted to facilitate controlled delivery of at least one active agent into a system in response to controlled changes in the pH of the system.

    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.
