High purity silica or fumed silica finds extensive usage in manufacturing semiconductors due to its high purity levels and ability to disperse well. It is used as an additive in chemical mechanical planarization slurries, dielectric films, and photoresist films in semiconductor manufacturing. Growing demand for electronics and requirement of more compact and powerful electronic devices is propelling the semiconductor industry. This in turn is augmenting the need for high purity silica. ... Read more
