摘要： Disclosed is a method for microwave plasma processing characterized by providing a plasma processing period of time having no radio-frequency voltage applied to the sample stage. Particularly, if the present invention is used for the shaping by etching of the conductive material layer provided on an underlying insulation material, effects such as shortening of processing time and improvement of etching accuracy can be obtained in the case that the radio-frequency voltage is applied only for the period of time for removing the surface oxide film of the portion to be etched, or in the case that the radio-frequency voltage is further applied until nearly the time to initiate over-etching, and, the latter case is also effective for making the side wall of the portion to be etched vertical.

摘要： In a dry-processing apparatus adapted for vapor phase deposition or vapor phase etching, the processing space in its processing chamber is covered with a cooled member provided for trapping reflecting active particles and preventing degassing, thereby permitting processing with gas of high purity substantially free from impurities. The active particles are incident upon a workpiece in a unidirectional flow. Means for uniformalyzing the direction of movement of active particles may be further provided. The apparatus is especially useful for vertical etching of a semiconductor substrate with neutral radicals.
