Abstract: A semiconductor device includes a plurality of first conductive patterns separated by a damascene pattern, a second conductive pattern buried in the damascene pattern, and a spacer including an air gap between the second conductive pattern and the first conductive patterns.

Abstract: An apparatus and method for storing an image in a storage folder corresponding to a file name in a mobile device are provided. The method includes obtaining a keyword list by analyzing a file name of the data to be stored, searching for at least one storage folder having a folder name corresponding to at least one keyword included in the keyword list, determining one of the found storage folders, and storing the data in the determined storage folder.

Abstract: A mobile communication terminal for providing a Radio Frequency IDentification (RFID) service interworking with video telephony and a method thereof are provided. The mobile communication system includes a first mobile communication terminal for generating RFID service information by using RFID tag information and for transmitting the generated information to a second mobile communication terminal, and the second mobile communication terminal for parsing the RFID service information received from the first mobile communication terminal and for outputting the parsed RFID service information.

Abstract: An apparatus and method for storing an image in a storage folder corresponding to a file name in a mobile terminal are provided. The method includes detecting a keyword by analyzing a file name of data to be stored, and storing the data in a storage folder corresponding to the keyword.

Abstract: An apparatus and method for sending/receiving a text message during a video call in a mobile terminal are provided. The method for sending the text message during the video call in the mobile terminal includes detecting a key input for a text message to be sent to at least one other party during the video call; creating a video call control message containing key input data of the text message; and sending the video call control message to the at least one other party. Because the text message is sent and received over a communication channel that has been already connected during the video call, the mobile terminal can provide a real-time text message service and can also provide a video call service even in a situation where a user cannot hear the at least one other party's voice.

Abstract: An apparatus and a method for casting video and audio data to a web during video telephony in a mobile communication terminal are provided. The method includes sending a transmitting request message to a counterpart terminal, if a transmitting request menu is selected in a video telephony mode, sending authentication information to a server, if a transmitting accept message is received from the counterpart terminal, and transmitting video telephony data to the server, if an authentication complete message is received from the server.
