Abstract
Fabrication method for a semiconductor memory device and structure are provided, which includes: providing at least two mask layers over a pair of fin structures extended above a substrate, wherein a first mask layer of the at least two mask layers is orthogonal to a second mask layer of the at least two mask layers; and patterning the pair of fin structures to define a pass-gate transistor, wherein the first mask layer facilitates removing of a portion of a first fin structure of the pair of fin structures to define a first pass-gate fin portion of the pass-gate transistor, and the second mask layer protects a second fin structure of the pair of fin structures to define a second pass-gate fin portion of the pass-gate transistor.
