Abstract:
A method for fabricating a semiconductor device includes: forming a mold stack pattern including a plurality of openings in an upper portion of a substrate and including a mold layer and a supporter layer which are stacked; forming a bottom electrode layer filling the plurality of the openings and covering the supporter layer; forming a filler portion disposed inside the plurality of the openings, a barrier portion extended upwardly from the filler portion, and an electrode cutting portion exposing a surface of the supporter layer by selectively etching the bottom electrode layer; forming a supporter by using the barrier portion as an etch barrier and etching the supporter layer exposed by the electrode cutting portion; selectively removing the barrier portion to form a hybrid pillar-type bottom electrode disposed inside the plurality of the openings; and removing the mold layer.

Claim (Index 9):
The method of  claim 1 , wherein the forming of the filler portion disposed inside the plurality of the openings, the barrier portion extended upwardly from the filler portion, and the electrode cutting portion exposing the surface of the supporter layer by selectively etching the bottom electrode layer includes:\n forming a supporter mask layer over the bottom electrode layer; and etching the bottom electrode layer by using the supporter mask layer as an etch barrier, wherein a bottom surface of the electrode cutting portion is disposed at a depth, with which the electrode cutting portion does not overlap with the filler portion.
