A method for fabricating a storage node electrode in a semiconductor device includes: performing a primary high density plasma (HDP) process to form a first HDP oxide film over an etch stop film; performing a secondary HDP process to form a second HDP oxide film on the first HDP oxide film; forming a support film over the second HDP oxide film; performing a tertiary HDP process to form a third HDP oxide film over the support film; forming a storage node electrode on an exposed surface of the storage node contact hole; partially removing the third HDP oxide film and the support film so that a support pattern supporting the storage node electrode is formed; and exposing an outer surface of the storage node electrode by removing the second HDP oxide film and the first HDP oxide film.
