Lowering the temperature at which an oxide layer is formed produces a passivation layer with improved adhesion characteristics and crack resistance. The method of forming the passivation layer includes first forming an intermetal dielectric layer over a lower metal layer of a semiconductor device. A via is formed in the intermetal dielectric layer. A metal line is formed on the via. A passivation layer is formed over the substrate including the metal line, the passivation layer being formed at a temperature of 300~350° C. by a high density plasma chemical vapor deposition process.
