A semiconductor device manufacturing method, the method including: forming an insulation layer having a protruding portion, the insulation layer having a surface and a rising surface that protrudes upward from the surface, on a semiconductor substrate; forming a conductive layer to cover the insulation layer having the protruding portion; and removing a predetermined region of the conductive layer by patterning the predetermined region according to an etching process using microwave plasma, which uses a microwave as a plasma source, while applying bias power of 70 mW/cm2 or above on the semiconductor substrate, under a high pressure condition of 85 mTorr or above. |
