Abstract: A semiconductor device includes a substrate. A plurality of horizontal structures is stacked on the substrate and spaced apart from each other. A plurality of vertical structures penetrates through the plurality of horizontal structures. Each of the plurality of vertical structures includes a vertical source line, a vertical bit line, a channel layer, and a dielectric layer. The channel layer is in direct contact with the vertical source line and the vertical bit line. The dielectric layer is disposed between the plurality of horizontal structures and the channel layer. Each of the plurality of horizontal structures includes a first conductive layer, a ferroelectric layer surrounding at least a portion of the first conductive layer, and a second conductive layer disposed between the ferroelectric layer and the dielectric layer.

Abstract: A semiconductor device includes a substrate, an etch stop layer on the substrate, a through-hole electrode extending through the substrate and the etch stop layer in a vertical direction substantially perpendicular to an upper surface of the substrate, and a conductive pad. The etch stop layer includes a first surface adjacent to the substrate and a second surface opposite the first surface. The through-hole electrode includes a protrusion portion that protrudes from the second surface of the etch stop layer. The conductive pad covers the protrusion portion of the through-hole electrode. The protrusion portion of the through-hole electrode is not flat.
