Abstract:
A method of manufacturing a semiconductor device including at least a thin film transistor, said method comprising the steps of:forming a semiconductor island over a substrate;forming a gate electrode adjacent to the semiconductor film;forming a gate insulating film between the semiconductor film and the gate electrode;forming source and drain regions in the semiconductor island;wherein the step of forming the gate insulating film includes the following steps of:arranging a pair of parallel planar type electrodes, wherein a distance between the parallel planar type electrodes is not larger than 10 mm;arranging a plurality of electrodes in such a manner that the plurality of electrodes may cross each other;placing the substrate in a space between the parallel planar type electrodes parallel thereto;supplying a process gas comprising an organic silane into the space;applying a first power to the parallel planar type electrodes to generate a plasma;applying a second power to the plurality of electrodes to form an electric field having a Lissajous' waveform in a plane parallel to a surface of the substrate in order to improve step coverage; andirradiating the substrate with an ultraviolet light.
