Zusammenfassung:A silicon dry etching method of the invention, includes: preparing a silicon substrate; forming a mask pattern having an opening on the silicon substrate; forming a deposition layer on the silicon substrate in accordance with the mask pattern while introducing a first gas; carrying out a dry etching process with respect to the silicon substrate in accordance with the mask pattern while introducing a second gas, and thereby forming a recess pattern on a surface of the silicon substrate; and carrying out an ashing process with respect to the silicon substrate while introducing a third gas.
