Abstract
PURPOSE: To manufacture a semiconductor having high etching selectivity and high preciseness, either by arranging a molded material made of F-contg. high molecular cpd. in a reaction vessel, or by arranging a Si substrate holder made of the moled material at the same time with the introduction of O2 and N2 into the reaction vessel in order to produce plasma.
CONSTITUTION: A holder 6 composed of a molded material made of a F-contg. high molecular cpd., e.g., TFE, is arranged in a reaction tube 3. The tube 3 is evacuated through an exhaust opening 2, and is charged with etching gas, e.g., O2, N2, and the vacuum is adjusted to about 1 Torr. A high frequency power, e.g., 14MHz, 100W in output, is applied to a coil 4 to produce plasma, so that portions to be etched of the surfaces of a Si substrates 5 set on the holder 6 are reacted with the activated gas so as to cause etching. This method makes it possible to control etching rate by adjusting the surface area of the molded material made of F-contg. high molecular cpd.
