Abstract
A 3D semiconductor device and a method of manufacturing the same are provided. The method includes forming a first semiconductor layer including a common source node on a semiconductor substrate, forming a transistor region on the first semiconductor layer, wherein the transistor region includes a horizontal channel region substantially parallel to a surface of the semiconductor substrate, and source and drain regions branched from the horizontal channel region to a direction substantially perpendicular to the surface of the semiconductor substrate, processing the first semiconductor layer to locate the common source node corresponding to the source region, forming a gate in a space between the source region and the drain region, forming heating electrodes on the source region and the drain region, and forming resistance variable material layers on the exposed heating electrodes.
