Abstract:
Technologies for manufacturing spin transfer torque memory (STTM) elements are disclosed. In some embodiments, the technologies include methods for interrupting the electrical continuity of a re-deposited layer that may form on one or more sidewalls of an STTM element during its formation. Devices and systems including such STTM elements are also described.

Claim (Index 26):
A method of forming a spin transfer torque memory (STTM) element, comprising:\n providing an STTM precursor comprising a substrate, a conductive layer on the substrate, and a material stack on the conductive layer, at least a portion of the material stack defining a magnetic tunnel junction (MTJ) including a fixed magnetic layer, a first dielectric layer comprising a first dielectric material, and a free magnetic layer, the magnetic tunnel junction comprising at least one sidewall, wherein a re-deposited layer is present on at least one of said sidewalls, the re-deposited layer comprising components of at least one of said fixed magnetic layer, dielectric layer, and free magnetic layer; depositing a non-conformal second dielectric layer comprising a second dielectric material on an upper surface of said substrate, said conductive layer, and said MTJ, such that at least a portion of said re-deposited layer is exposed; and selectively removing at least some of the exposed portion of said re-deposited layer, so as to form a gap in said re-deposited layer.
