摘要:
A semiconductor device, and a method of fabricating the semiconductor device, which is able to prevent a leaning phenomenon from occurring between the adjacent storage nodes. The method includes forming a plurality of multi-layered pillar type storage nodes each of which is buried in a plurality of mold layers, wherein the uppermost layers of the multi-layered pillar type storage nodes are fixed by a support layer, etching a portion of the support layer to form an opening, and supplying an etch solution through the opening to remove the multiple mold layers. A process of depositing and etching the mold layer by performing the process 2 or more times to form the multi-layered pillar type storage node. Thus, the desired capacitance is sufficiently secured and the leaning phenomenon is avoided between adjacent storage nodes.
