Abstract
A semiconductor device includes a substrate, first and second supporter patterns spaced vertically from the substrate, the second supporter pattern being spaced vertically from the first supporter pattern, a lower electrode hole extending vertically on the substrate, a lower electrode inside the lower electrode hole, contacting a sidewall of the first and second supporter patterns, the lower electrode including a first layer along a portion of a sidewall and bottom surface of the lower electrode hole, a second layer between the first layers, and a third layer on an upper surface of the first and second layers, the first and second layers including a material different from the second layer, and a sidewall of at least a portion of the third layer being concave toward the third layer, overlapping the second layer in the vertical direction, and being spaced apart from the second layer in the vertical direction.
