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 13):
The method of  claim 11 , wherein the film stack comprises:\n a first aperture layer comprising a thickness between 5 nm and 30 nm; a first offset layer disposed in physical contact with the first aperture layer, the first offset layer comprising a thickness between 300 nm and 1000 nm; a second aperture layer disposed in physical contact with the first offset layer, the second aperture layer comprising a thickness between 5 nm and 30 nm; and a second offset layer disposed in physical contact with the second aperture layer, the second offset layer comprising a thickness between 20 nm and 50 nm.
