Abstract:
Methods for additive formation of a STT-MRAM metal stack using a deposition process through a pre-patterned template that skims away metal ions that are less likely to enable anisotropic deposition on a substrate. The pre-patterned template is formed from a film stack using patterning techniques to form an opening in the film stack that exposes portions of an underlying substrate where a MTJ will be formed for an MRAM cell. The film stack cavity may be exposed to etch processes that selectively pull back the sidewall, such that other layers in the film stack protrude into the cavity. Additional treatments to the other layers may alter the opening sizes in the other layers. Metal deposited through the cavity such that metal ions with anisotropic characteristics will be skimmed away before reaching the substrate.

Claim (Index 7):
The method of  claim 1 , wherein the removing of the at least one offset layer comprises removing portions of a first aperture layer at a higher rate than a second aperture layer that is disposed between the first aperture layer and the substrate.
