Abstract
A semiconductor device includes a bottom electrode structure disposed over a semiconductor substrate. The bottom electrode structure includes a first metal layer, a second metal layer, a third metal layer, a fourth metal layer, and a fifth metal layer from bottom to top. The first metal layer, the third metal layer and the fifth metal layer include a first metal material, and the second metal layer and the fourth metal layer include a second metal material different from the first metal material. The semiconductor device also includes a high-k dielectric structure disposed on opposite sidewalls of the bottom electrode structure. The opposite sidewalls of the bottom electrode structure are step-shaped. The semiconductor device further includes a top electrode structure laterally surrounding the bottom electrode structure and separated from the bottom electrode structure by the high-k dielectric structure.
