    Abstract: Some embodiments of the present disclosure relate to a method that achieves a substantially uniform pattern of magnetic random access memory (MRAM) cells with a minimum dimension below the lower resolution limit of some optical lithography techniques. A copolymer solution comprising first and second polymer species is spin-coated over a heterostructure which resides over a surface of a substrate. The heterostructure comprises first and second ferromagnetic layers which are separated by an insulating layer. The copolymer solution is subjected to self-assembly into a phase-separated material comprising a pattern of micro-domains of the second polymer species within a polymer matrix comprising the first polymer species. The first polymer species is then removed, leaving a pattern of micro-domains of the second polymer species. A pattern of magnetic memory cells within the heterostructure is formed by etching through the heterostructure while utilizing the pattern of micro-domains as a hardmask.

    Abstract: Some embodiments of the present disclosure relate to a method that achieves a substantially uniform pattern of discrete storage elements comprising a substantially equal size within a memory cell. A copolymer solution comprising first and second polymer species is spin-coated onto a surface of a substrate and subjected to self-assembly into a phase-separated material comprising a regular pattern of micro-domains of the second polymer species within a polymer matrix comprising the first polymer species. The first or second polymer species is then removed resulting with a pattern of micro-domains or the polymer matrix with a pattern of holes, which may be utilized as a hard-mask to form a substantially identical pattern of discrete storage elements through an etch, ion implant technique, or a combination thereof.

    Abstract: Some embodiments of the present disclosure relates to a hybrid gate dielectric layer that has good interface and bulk dielectric properties. Surface traps can degrade device performance and cause large threshold voltage shifts in III-N HEMTs. This disclosure uses a hybrid ALD (atomic layer deposited)-oxide layer which is a combination of H2O-based and O3/O2-based oxide layers that provide both good interface and good bulk dielectric properties to the III-N device. The H2O-based oxide layer provides good interface with the III-N surface, whereas the O3/O2-based oxide layer provides good bulk properties.
