  • SILICA SPHERICAL PARTICLES FOR SEMICONDUCTOR SEALING MATERIAL
    Publication number: 20220009783
    Abstract: The purpose of the present invention is to provide: silica particles of which the maximum particle diameter can be minimized and which can achieve proper fluidability that cannot be achieved by the conventional techniques; and silica spherical particles which, when used as a filler for a heat-dissipating sheet, can achieve excellent heat conductivity and flexibility. Silica spherical particles characterized in that, when particles each having a size of 5 ?m or more and imaged by an optical measurement are observed, the particle diameter of each of the particles, which is determined from the image, satisfies the following requirements. Requirements: D99?29 ?m, and 10 ?m?Dmode<D99, and D99/Dmode?1.5, and Dmode?20 ?m.
