Abstract

Methods of manufacturing a semiconductor device including a multi-layer of dielectric layers may include forming a metal oxide layer on a semiconductor substrate and forming a multi-layer of silicate layers including metal atoms and silicon atoms, on the metal oxide layer. The multi-layer of silicate layers may include at least two metallic silicate layers having different silicon concentrations, which are a ratio of silicon atoms among all metal atoms and silicon atoms included in the metallic silicate layer.
