Claim 18:
19. A method for forming an embedded magnetoresistive random access memory (MRAM) device, the method comprising:
forming a bottom electrode contact over one or more of a plurality of conductive lines;
constructing MRAM pillars over the bottom electrode contact, wherein the MRAM pillars have a cone-shaped configuration;
depositing an encapsulation layer over the MRAM pillars to define a tight pitch gap between a pair of the MRAM pillars;
etching the encapsulation layer to form a generally V-shaped gap between the pair of MRAM pillars such that an aspect ratio of the tight pitch gap is reduced; and
depositing a dielectric within the generally V-shaped gap between encapsulation layer portions of two adjacent MRAM pillars, wherein the dielectric fills an entirety of a space defined within the generally V-shaped gap.
