Definition of "Passivation" |
A chemical reaction that eliminates the detrimental effect of electrically reactive atoms on a photovoltaic cell's surface. / A chemical reaction that eliminates the detrimental effect of electrically reactive atoms on a semiconductor's surface. / Passivation, in physical chemistry and engineering, refers to a material becoming "passive," that is, being less affected by environmental factors such as air and water. / the process in which an insulting dielectric layer is formed over the surface of the die. Passivation is normally achieved by thermal oxidation of the silicon and a thin layer of silicon dioxide is obtained in this manner. Other passivation dielectric coatings may also be applied, such as silicon glass. |
