    摘要: Techniques are disclosed for fabricating a self-aligned spin-transfer torque memory (STTM) device with a dot-contacted free magnetic layer. In some embodiments, the disclosed STTM device includes a first dielectric spacer covering sidewalls of an electrically conductive hardmask layer that is patterned to provide an electronic contact for the STTM's free magnetic layer. The hardmask contact can be narrower than the free magnetic layer. The first dielectric spacer can be utilized in patterning the STTM's fixed magnetic layer. In some embodiments, the STTM further includes an optional second dielectric spacer covering sidewalls of its free magnetic layer. The second dielectric spacer can be utilized in patterning the STTM's fixed magnetic layer and may serve, at least in part, to protect the sidewalls of the free magnetic layer from redepositing of etch byproducts during such patterning, thereby preventing electrical shorting between the fixed magnetic layer and the free magnetic layer.

    摘要: Spin-transport elements using semiconductors have had the problem of higher element resistance than conventional GMR elements and TMR elements, making it difficult to obtain high magnetoresistance ratios. A magnetoresistive element including a semiconductor channel layer (3); a first ferromagnetic layer (12A) disposed on the semiconductor channel layer (3); a second ferromagnetic layer (12B) disposed away from the first ferromagnetic layer (12A); and a non-magnetic first reference electrode (20) disposed away from the first ferromagnetic layer (12A) and the second ferromagnetic layer (12B), wherein current is input from the second ferromagnetic layer (12B) to the first ferromagnetic layer (12A) through the semiconductor channel layer (3), a voltage between the second ferromagnetic layer (12B) and the first reference electrode (20) is output.
