    摘要: A magnetic memory cell and a magnetic random access memory that are highly reliable and low-power consuming. An upper electrode having a connecting area smaller than the area of a ferromagnetic free layer of a magnetic memory cell is connected to the ferromagnetic free layer. A current is applied to produce an uneven magnetic field over the magnetic memory cell, whereby spin-transfer torque magnetization reversal can be realized with low current and at small write error rate.

A channel layer 11 formed of a transparent semiconductor such as zinc oxide ZnO. A transparent electrode is used for all of a source 12, a drain 13 and a gate 14, or a part of them. As the transparent electrode, a transparent conductive material such as conductive ZnO doped with, for example, group III elements is used. As a gate insulating layer 15, a transparent insulative material such as insulative ZnO doped with elements capable of taking a valence of one as a valence number or group V elements is used. If a substrate 16 must be transparent, for example, glass, sapphire, plastic or the like can be used as a transparent material.

    摘要: A nuclear spin control device comprises a first semiconducting layer with spin-up carriers, a second semiconducting layer with spin-down carriers; and a third semiconducting layer arranged between the first and the second semiconducting layers. The third semiconducting layer can be tunnelled selectively by the spin-up carriers and the spin-down carriers such that nuclear spin in the third semiconducting layer selectively interacts with the carriers so as to be oriented into a desired direction. The device may be adapted to control the shape of a wave function so as to cover nuclear spins in the third semiconducting layer and propagate information of one nuclear spin to another nuclear spin.

    摘要: In a thin film transistor, a gate insulating film having a first insulating film and a second insulating film is formed on a gate electrode, and a semiconductor layer including ZnO etc. is formed on the second insulating film. The first insulating film is formed by using SiNx having a high insulating characteristic, and the second insulating film is formed by using an oxide (for example, SiO2). This structure improves a crystalline characteristic of the semiconductor layer that constitutes an interface in combination with the second insulating film, and decreases a defective level of the interface between the semiconductor layer and the second insulating film. Further, the second insulating film is constituted of the oxide, so that it is possible to restrain a material for the second insulating film from depriving oxygen of the semiconductor layer. This keeps a crystalline characteristic of the semiconductor layer under a preferable condition in the vicinity of the interface between the second insulating film and the semiconductor layer. As a result, it is possible to realize a thin film transistor such that: a leak current level at an OFF area is low, and the mobility is high, and a switching characteristic is preferable. Thus, in the thin film transistor having a transparent semiconductor film, a TFT characteristic is improved.

    摘要: [Object] To provide a method of manufacturing a perpendicular magnetization-type magnetic element, which does not need a step of depositing MgO.[Solving Means] The method of manufacturing a magnetoresistive element 1 according to the present invention includes laminating a first layer 30 on a base 10, the first layer 30 including a material containing at least one of Co, Ni, and Fe. Next, a second layer 40 is laminated on the first layer 30, the second layer 40 including Mg. Next, the Mg in the second layer 40 is oxidized to form MgO by applying an oxidation treatment to a laminated body including the first layer 30 and the second layer 40. Next, the second layer 40 is crystallized by applying a heat treatment to the laminated body, and the first layer 30 is caused to be perpendicularly magnetized. According to the manufacturing method, it is possible to manufacture a perpendicular magnetization-type CoFeB—MgO magnetic element without causing a problem arising from the deposition of MgO.
