An HARQ method for guaranteeing a QoS in a wireless communication system is provided. In a transmitting apparatus using a HARQ for transmitting packet data in a wireless communication system, a retransmission controller determines the size of redundancy information for correcting transmission errors in packet data, and a transmitter transmits the redundancy information of the determined size upon request for a retransmission of the packet data. Transmission of redundancy information of a variable size at each retransmission satisfies the QoS required for each user, maximizes a data throughput, and allows for the efficient reception of an ACK or a NACK for the redundancy information.

A semiconductor device and a method for forming the same are disclosed. The semiconductor device includes a semiconductor substrate including a cell region and a peripheral circuit region, and an active region defined by a device isolation film, at least one dummy gate formed over the active region to expose a center part and both ends of the active region, a bit line contact plug formed between the dummy gates so as to be coupled to the center part of the active region, and a storage node contact plug that is spaced apart from the bit line contact plug by the dummy gate and is coupled to both ends of the active region. As a result, the problem that the storage node contact hole is not open in the semiconductor device can be solved, resulting in improved semiconductor device characteristics.

A touch-screen display device includes a touch panel and a display panel. The touch panel includes a signal terminal portion transmitting a coordinate signal corresponding to a touch position. The display panel is disposed under the touch panel, and includes a display area and a peripheral area that surrounds the display area. An image is displayed in the display area. A first terminal portion is disposed in the peripheral area and electrically connected to the signal terminal portion. Thus, the first terminal portion is formed on the display panel, and thus the coordinate signal may be directly transmitted to a main flexible printed circuit board (FPCB) through the first terminal portion, so that the coordinate signal may be stably transmitted.
