Abstract: A gate insulating layer, an amorphous silicon layer, a doped amorphous silicon layer and a Cr layer are sequentially deposited on a substrate on which a gate wire is formed. Next, the Cr layer is patterned to form a data line, a source electrode and a drain electrode. The doped amorphous silicon layer and the amorphous silicon layer are patterned at the same time, and the doped amorphous silicon layer is etched by using the data line, the source electrode and the drain electrode as etch stopper. Subsequently, a passivation layer is deposited and patterned to form a contact hole. An ITO layer is deposited and patterned to form a pixel electrode. According to the present invention, an oxide layer is prevented by performing a sequential deposition of the four layers in a vacuum state. As a result, the on current of the TFT is increased, and HF cleaning is not necessary because no oxide layer is formed. Therefore, the overall TFT manufacturing process is simplified.

Abstract: Disclosed is a satellite tracking antenna applied to a satellite tracking antenna system mounted on a vehicle and method using rotation of a subreflector. The antenna includes a reflector controlled to be oriented toward a target satellite, a subreflector for reflecting a signal reflected from the reflector to an entrance end and for identifying relative signals of upper, lower, left, and right sides of the satellite, a subreflector rotating part for rotating the subreflector at a high RPM, a driving device for driving the reflector in at least one of elevation and azimuth directions, and a fixing member for fixing the antenna system on the vehicle. Thus, since the tracking mechanism is realized by operating the elevation and azimuth motors only using the subreflector, the structure of the antenna can be simplified and the satellite tracking is accurately performed.
