Abstract
A semiconductor device include a substrate including at least a memory cell region formed thereon, an isolation mesh formed on the substrate; and a plurality of storage node contact plugs. The semiconductor device includes a plurality of memory cells formed in the memory cell region. The isolation mesh includes a plurality of essentially homogeneous dielectric sidewalls and a plurality of first apertures defined by the dielectric sidewalls. The storage node contact plugs are respectively formed in the first apertures, and electrically connected to the memory cells respectively.
