Abstract
A method for fabricating a semiconductor device includes forming, over a substrate, a plurality of first conductive structures which are separated from one another; forming multi-layered dielectric patterns including a first dielectric layer which covers upper ends and both sidewalls of the first conductive structures; removing portions of the first dielectric layer starting from lower end portions of the first conductive structures to define air gaps, and forming second conductive structures which are filled between the first conductive structures.
