Abstract
A semiconductor device includes a switching device disposed on a substrate. A buffer electrode pattern is disposed on the switching device. The buffer electrode pattern includes a first region having a first vertical thickness, and a second region having a second vertical thickness smaller than the first vertical thickness. A lower electrode pattern is disposed on the first region of the buffer electrode pattern. A trim insulating pattern is disposed on the second region of the buffer electrode pattern. A variable resistive pattern is disposed on the lower electrode pattern.
