Abstract: A method of manufacturing a semiconductor device may include forming a material layer on a substrate, performing a selective oxidation process to form a capping oxide layer on a first surface of the material layer, wherein a second surface of the material layer is not oxidized, and etching the material layer through the second surface to form a material pattern. An etch rate of the capping oxide layer is less than an etch rate of the material layer. A semiconductor device may include a lower electrode on a substrate, a data storage part on a top surface of the lower electrode, an upper electrode on the data storage part, and a capping oxide layer arranged on at least a portion of a top surface of the upper electrode. The capping oxide layer may include an oxide formed by oxidation of an upper surface of the upper electrode.

Abstract: A semiconductor device includes a semiconductor substrate, a peripheral device on the semiconductor substrate, a lower insulating structure on the semiconductor substrate and covering the peripheral device, a first conductive line on the lower insulating structure, a memory cell structure on the first conductive line, and a second conductive line on the memory cell structure. The memory cell structure may include an information storage material pattern and a selector material pattern on the lower insulating structure in a vertical direction. The selector material pattern may include a first selector material layer including a first material and a second selector material layer including a second material. The second selector material layer may have a threshold voltage drift higher than that of the first material. The second selector material layer may have a second width narrower than a first width of the first selector material layer.

Abstract: An augmented reality (AR) device including a variable focus lens of which a focal length may be changed by adjusting refractive power and adjusting the position of a focus adjustment region of the variable focus lens according to a direction of the user's view. The AR device may obtain an eye vector indicating a direction of the user's view using an eye tracker, adjust a refractive power of a first focus adjustment region of a first variable focus lens to change a focal length for displaying a virtual image, and complementarily adjust a refractive power of a second focus adjustment lens with respect to the adjusted refractive power of the first focus adjustment region.
