ABSTRACT:
A semiconductor memory cell structure having 4F2dimensions and method for forming the same. The memory cell is formed on a surface of a substrate and includes an active region formed in the substrate, a semiconductor post formed on the surface of the substrate over the active region and a capacitor is formed on the semiconductor post. A vertical access transistor having a gate structure formed on the semiconductor post is configured to electrically couple the respective memory cell capacitor to the active region when accessed.
