Abstract

See full text

A conformal coating comprising modified porous silica particles is disclosed. A porous silica particle, such as MCM-14 or SBA-15 is modified with a sulfur gettering functionality, such as a phosphine compound, covalently bonded to silicon atoms in the porous silica particle. The conformal coating comprising the modified porous silica particles may be applied to metallic wiring areas of a circuit component, with the sulfur gettering functionality preventing sulfur from atmospheric gasses from penetrating the conformal coating to the metallic wiring.
