发明名称 Semiconductor device fabrication method and fabrication apparatus
摘要 The flatness of the surface of a Si substrate is requested as the present gate length is miniaturized. The present invention is a semiconductor device fabrication method for flattening a silicon surface by continuously supplying a high-temperature fluoride ammonium solution to the surface a silicon substrate in which at least the silicon surface is locally exposed.
