摘要
Dangling bonds of silicon atoms tend to take place in silicon oxide grown on a silicon wafer due to oxygen deficiency; hypofluorous acid is introduced into the silicon oxide so that the hypofluorous acid reaches the dangling bonds through diffusion; the hypofluorous acid is decomposed into fluorine atoms and hydroxyl groups, and the fluorine atoms and hydroxyl groups deactivate the dangling bonds of silicon atoms; even if electric charges are injected into the silicon oxide, the deactivation is never broken so that the silicon oxide layer is stable and highly reliable.
