Abstract:
A semiconductor device includes a substrate, a stack, and channel structures penetrating the stack. The stack includes gate electrodes and insulating layers alternately and repeatedly stacked on the substrate, and extending in a first direction. The channel structures in a first row are spaced apart from each other in the first direction. The stack includes a first sidewall that includes first recessed portions and first protruding portions. Each of first recessed portions is defined by an adjacent pair of the first recessed portions. Each of the first recessed portions has a shape recessed toward a first region of the stack between an adjacent pair of the channel structures of the first row. Each of the first recessed portions has a width that decreases in a direction toward the first region when measured along the first direction.
Abstract:

Abstract:
An apparatus and a method for photographing an image in an electronic device having a camera are disclosed. The electronic device may include an image sensor, an image signal processor configured to process an image obtained by the image sensor, an audio processing unit configured to process a sound received from a microphone, a storage unit configured to store data, and a control unit configured to implement the method. The method may include recording for a set period of time, a series of images and a series of sounds using the image sensor and the microphone when a sound photographing mode is active, selecting a particular sound from the series of sounds having a high correlation with a particular image from the series of images, and synthesizing the particular sound with the particular image and store in the storage unit the synthesized particular sound with the particular image.
