Abstract
A semiconductor device includes a bottom electrode contact disposed over one or more of a plurality of conductive lines, magnetoresistive random access memory (MRAM) pillars constructed over the bottom electrode contact, an encapsulation layer section disposed between a pair of the MRAM pillars such that an aspect ratio of a tight pitch gap between the pair of the MRAM pillars is reduced, and a dielectric disposed within the encapsulation layer section, wherein the dielectric fills an entirety of a space defined within the encapsulation layer section. The MRAM pillars have a generally rectangular-shaped or cone-shaped configuration and the encapsulation layer section has a generally U-shaped or V-shaped configuration.
