Abstract: A coil component is provided. The coil component includes a body having fifth and sixth surfaces opposing each other, first and second surfaces respectively connecting the fifth and sixth surfaces of the body and opposing each other, and third and fourth surfaces respectively connecting the first and second surfaces of the body and opposing each other in one direction, a recess disposed in an edge between one of the first and second surfaces of the body and the sixth surface of the body, a coil portion disposed inside the body and exposed through the recess, and an external electrode including a connection portion disposed in the recess and connected to the coil portion, and a pad portion disposed on one surface of the body. A length of the pad portion in the one direction is greater than a length of the connection portion in the one direction.

Abstract: An apparatus for inspecting a semiconductor and a method for automatically cleaning the tip of a probe card may include an inspection chamber having a probe card for inspecting a wafer, and a chemical-wetting chamber for applying a chemical agent to a cleaning member. The inspection chamber and the chemical-wetting chamber may be integral parts of the apparatus.

Abstract: A data transmission method which maintains the direct current (DC) balancing of each channel and compensates for the skew between channels when digital video data made up of graphic data, control data and clock data is transmitted in series via channels allocated to the data, and a data receiving method, a data transmitter and a data receiver, are provided. In this method, the disparity representing the degree of the direct current (DC) balancing of the graphic data is calculated whenever the graphic data is transmitted. The calculated disparities are accumulated whenever the graphic data is transmitted. Scrambling is performed in which, when the accumulated disparity does not amount to the predetermined critical value, the received graphic data is transmitted without change, and when the accumulated disparity amounts to the predetermined critical value, the received graphic data is inverted.
