Hdp passivation

WebA mechanism of the ultraviolet (UV)-induced degradation of SiNx:H passivation is investigated from the viewpoint of PECVD-induced defects. Due to the PECVD, the damaged layer with around 50 nm is formed near the Si surface. These defects are passivated with hydrogen atoms, resulting in low recombination velocity at this region. … WebFeb 21, 2011 · The maximum amount of phosphorous that can be added to the passivation oxide (post metallization) is constrained by the stability of the as-deposited, undensified …
