Abstract
A semiconductor device according to an embodiment includes a substrate, a bit line and a source line extending in a vertical direction substantially perpendicular to a surface of the substrate, a semiconductor layer disposed between the source line and the bit line on a plane substantially parallel to the surface of the substrate, a non-ferroelectric layer pattern disposed on the semiconductor layer, a floating electrode layer pattern disposed on the non-ferroelectric layer pattern, a ferroelectric layer pattern disposed on the floating electrode layer pattern, and a word line disposed on the ferroelectric layer pattern. An overlap area between the floating electrode layer pattern and the non-ferroelectric layer pattern in the vertical direction is greater than an overlap area between the ferroelectric layer pattern and the word line in the vertical direction.
