Abstract:
Methods and architectures for self-aligned build-up of patterned features. An initial patterned feature aspect ratio may be maintained or increased, for example to mitigate erosion of the feature during one or more subtractive device fabrication processes. A patterned feature height may be increased without altering an effective spacing between adjacent features that may be further relied upon, for example to further pattern an underlying material. A patterned feature may be conformally capped with a material, such as a metal or dielectric, in a self-aligned manner, for example to form a functional device layer on an initial pattern having a suitable space width-to-line height aspect ratio without the use of a masked etch to define the cap.

Claim (Index 21):
A nanofabrication method, comprising:\n patterning a pair of features having sidewalls that define a space there between; depositing a first material layer over a top surface of the features and over the sidewalls; depositing a second material layer over the first material layer, wherein deposition of the second material is insufficiently conformal to form the second material layer over all portions of the first material layer adjacent to the sidewalls; and exposing at least a portion of the sidewalls by removing regions of the first material layer unprotected by the second material layer while retaining the first material layer over the top surface of the features.
