Abstract: Embodiments of mechanisms for forming dislocations in source and drain regions of finFET devices are provided. The mechanisms involve recessing fins and removing the dielectric material in the isolation structures neighboring fins to increase epitaxial regions for dislocation formation. The mechanisms also involve performing a pre-amorphous implantation (PAI) process either before or after the epitaxial growth in the recessed source and drain regions. An anneal process after the PAI process enables consistent growth of the dislocations in the source and drain regions. The dislocations in the source and drain regions (or stressor regions) can form consistently to produce targeted strain in the source and drain regions to improve carrier mobility and device performance for NMOS devices.

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.
