A semiconductor device which does not reduce writing property of a memory element and a method for manufacturing the same are proposed even in the case of forming a silicon film at a step portion formed by a surface of a substrate and a wiring formed over the substrate. The semiconductor device includes a plurality of the memory elements comprising a first electrode formed over a substrate having an insulating surface, sidewall insulating layer formed on side surface of the first electrode, a silicon film formed to cover the first electrode and the sidewall insulating layer, and a second electrode formed over the silicon film, and at least one of the first electrode and the second electrode is formed with a material being capable of being alloyed with the silicon film. |
