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 3):
The method of  claim 1 , wherein the forming of the bottom electrode layer includes:\n conformally forming a first bottom electrode layer over the plurality of the openings and the supporter layer in such a manner than a gap is defined inside each of the plurality of the openings; and forming a second bottom electrode layer filling the gap over the first bottom electrode layer.
