Abstract
A semiconductor device may include a first electrode, a second electrode, an insulating layer interposed between the first electrode and the second electrode and including an opening having an inclined sidewall, a variable resistance layer formed in the opening, and a liner interposed between the variable resistance layer and the insulating layer and between the variable resistance layer and the first electrode. The variable resistance layer includes a first surface and a second surface, the first surface facing the first electrode and having a first area, the second surface facing the second electrode and having a second area different from the first area. The variable resistance layer maintains an amorphous state during a program operation.
