Abstract: A semiconductor device includes a stack structure including interlayer insulating layers and horizontal layers on a lower structure; a memory vertical structure vertically penetrating the stack structure; first and second barrier structures penetrating the stack structure in parallel; a supporter pattern penetrating the stack structure; and through contact plugs penetrating the stack structure. The first barrier structure includes first barrier patterns arranged in a first direction and spaced apart from each other, and second barrier patterns arranged in the first direction and spaced apart from each other. Each of the first and second barrier patterns includes a linear shape extending in the first direction. In a first barrier pattern and a second barrier pattern adjacent to each other, a portion of the first barrier pattern opposes a portion of the second barrier pattern in a second direction perpendicular to the first direction.

Abstract: A window includes a base region and a compressive stress region disposed on the base region. The compressive stress region includes Li+, Na+, and K+ ions. The compressive stress region includes a first compressive stress portion in which a concentration of the K+ ions decreases, a concentration of Na+ ions increases, and a concentration of the Li+ ions increases, from a surface of the window toward the base region. A second compressive stress portion is adjacent to the first compressive stress portion. In the second compressive stress portion, the concentration of the Na+ ion decreases and the concentration of the Li+ ion increases, from the first compressive stress portion toward the base region. The window thereby has a high surface compressive stress value and impact resistance.

Abstract: A cover window of a display device includes: a transparent layer; a light blocking layer disposed on the transparent layer, the light blocking layer defining an opening therein, the opening exposing a portion of the transparent layer which corresponds to a sensor of the display device; and an anti-pollution layer disposed corresponding to the portion of the transparent layer which corresponds to the sensor of the display device and is exposed by the opening. The anti-pollution layer has a surface energy lower than each of a surface energy of the transparent layer and a surface energy of the light blocking layer.
