Abstract:
Methods of fabricating semiconductor devices are provided. A substrate having active patterns and isolating layer patterns is prepared. Each of the isolating layer patterns has an upper surface higher than that of each of the active patterns. A spacer layer having a uniform thickness is formed on the substrate. The spacer layer is etched to form a spacer on a sidewall of each of the isolating layer patterns. A gate structure is formed on each of the active patterns. A selective epitaxial growth (SEG) process is performed on the active patterns having the gate structure to form isolated epitaxial layers that have upper surfaces higher than those of the isolating layer patterns, on the active patterns. Related semiconductor devices are also provided.
Abstract:
A method, system and apparatus for restricting, within a specific area, the photographing function of a camera mounted in a mobile terminal. A control signal is transmitted to a mobile terminal within a photograph-prohibited area and the mobile terminal disables the camera. Upon leaving the photograph-prohibited area, the camera is enabled.
Abstract:
In various embodiments, the present disclosure may provide a storage node. In various implementations, the storage node may include a bottom electrode having a non-planar bottom surface that conforms with and is connected to a non-planar top surface of a diode electrode of a memory device. The storage node may further include a phase change layer on top of a bottom diode and a top electrode on a top surface of a phase change layer.
Abstract:
Provided is a phase-change memory using a single-element semimetallic thin film. The device includes a storage node having a phase-change material layer and a switching element connected to the storage node, wherein the storage node includes a single-element semimetallic thin film which is formed between an upper electrode and a lower electrode. Thus, the write speed of the phase-change memory can be increased compared with the case of a Ge—Sb—Te (GST) based material.
Abstract:
Provided is a Vertical External Cavity Surface Emitting Laser (VECSEL). The VECSEL includes a semiconductor chip, a pump laser, a narrow bandwidth polarization filter, an external mirror, and a Second Harmonic Generation (SHG) element. The semiconductor chip includes an active layer generating light having a wavelength and a reflective layer reflecting the light generated in the active layer. The pump laser emits a pump beam for exciting the active layer. The narrow bandwidth polarization filter is formed on the semiconductor chip and polarizes the light. The external mirror faces the active layer, amplifies the light emitted from the active layer by repeatedly reflecting the light toward the reflective layer, and outputs the amplified light out of the VECSEL. The SHG element is disposed between the narrow bandwidth polarization filter and the external mirror and converts the wavelength of the light.

Abstract:
A process cartridge unit and an image forming apparatus having the same. The image forming apparatus includes a main body, a process cartridge unit removably mounted in the main body, an opening provided in the main body to permit the process cartridge unit to be installed or removed, and a cover rotatably mounted to the main body so as to expose or shield the opening. The process cartridge unit includes a container to store a developer and at least one knob coupled to the container. When the cover is closed, the knob is folded by the cover, and when the cover is opened, the knob is unfolded. Accordingly, since the position of the knob is changed, a mounting space of the process cartridge unit can be decreased, and a user can easily grasp the knob.
