Claim 0:
1. A method of forming multi-level device contact, comprising:
providing a substrate, the substrate defining a plane of the substrate and having an array of spacer features, disposed over an array of active device features, arranged in a first level; and
directing a reactive beam to the array of spacer features, the reactive beam defining a non-zero angle of incidence with respect to a perpendicular to the plane of the substrate, wherein a seed layer is deposited on a first portion of the array of spacer features, and is not deposited on a second portion of the array of spacer features,
wherein the reactive beam comprises a metallic species, and wherein the seed layer forms an array of staggered contacts, having an S-shape.
