Abstract:
The spacer in a spin-valve is replaced with an organic layer, allowing for numerous applications, including light-emitting structures. The invention demonstrates that the spin coherence of the organic material is sufficiently long that the carriers do not lose their spin memory even in traversing a thicker passive barrier. At least three methods to fabricate the organic spin-valve devices are disclosed, in which the difficulties associated with depositing the ferromagnetic (FM) and organic layers are addressed.
Abstract:
An improved and novel fabrication method for a magnetic element, and more particularly a magnetic element (10) including a first electrode (14) , a second electrode (18) and a spacer layer (16). The first electrode (14) includes a fixed ferromagnetic layer (26) having a thickness t1. A second electrode (18) is included and comprises a free ferromagnetic layer (28) having a thickness t2. A spacer layer (16) is located between the fixed ferromagnetic layer (26) and the free ferromagnetic (28) layer, the spacer layer (16) having a thickness t3, where 0.25t3
Abstract:
Submicron ferromagnets, of selected size and spacing, are introduced into semiconductor by means of ion implantation and subsequent heat treatments. The resulting semiconductor contains ferromagnets at high density and which exhibit Curie temperatures exceeding room temperature. The semiconductor retains its intrinsic physical properties, such as optical and transport properties, after incorporation of the ferromagnetic nanostructures.

Abstract:
A multi-layer magnetic memory cell is provided, with magnetic vectors aligned along a length of the cell. To align the magnetic end vectors, an ellipsoidal shape is formed at the ends of the memory cell. Magnetic vectors aligned along the length prevent from forming high fields and magnetic poles at the discontinuity or ends of the layers. The memory cell with the ellipsoidal shape shows a constant magnetic resistance of the magnetic cell when a magnetic field is applied to the cell and attains a reduction of power consumption for the magnetic cell.
Abstract:
A SiGe HBT is disclosed, which includes: a silicon substrate; shallow trench field oxides formed in the silicon substrate; a pseudo buried layer formed at bottom of each shallow trench field oxide; a collector region formed beneath the surface of the silicon substrate, the collector region being sandwiched between the shallow trench field oxides and between the pseudo buried layers; a polysilicon gate formed above each shallow trench field oxide having a thickness of greater than 150 nm; a base region on the polysilicon gates and the collector region; emitter region isolation oxides on the base region; and an emitter region on the emitter region isolation oxides and a part of the base region. The polysilicon gate is formed by gate polysilicon process of a MOSFET in a CMOS process. A method of manufacturing the SiGe HBT is also disclosed.
Abstract:
A storage medium storing computer readable program, a computer program product, a navigation apparatus and a control method thereof are disclosed. The navigation apparatus comprises a display unit, an input unit and a control unit. The display unit displays an electronic map and a point of interest (POI) cluster, the POI cluster includes a plurality of points of interest, and the input unit correspondingly generates a first operation signal according to a user's manipulation on the POI cluster. The control unit controls the display unit displaying the plurality of points of interest around the POI cluster according to the first operation signal.
Abstract:
A multi-chip module (MCM) is described. This MCM includes at least two substrates that are remateably mechanically coupled by positive and negative features on facing surfaces of the substrates. These positive and negative features may mate and self-lock with each other. For example, the positive features on one of the surfaces may include pairs of counterposed micro-springs, and the negative features may include pits or grooves on the other surface. When the substrates are mechanically coupled, a given pair of positive features may provide a force in a plane of the other surface. Furthermore, by compressing the MCM so that the surfaces of the substrates are pushed toward each other, the mechanical coupling may be released.
Abstract:
Compositions and methods are provided for prognostic classification of inflammatory diseases, e.g. inflammatory demyelinating disease, patients into subtypes, which subtypes are informative of the patient's need for therapy and responsiveness to a therapy of interest. The patterns of cytokines provides for a signature pattern that can identify patients likely to benefit from therapeutic intervention as well as discriminate patients that have a high probability of responsiveness to a therapy from those that have a low probability of responsiveness. Assessment of this signature pattern thus allows improved methods of care. In one embodiment of the invention, the autoimmune disease is multiple sclerosis or neuromyelitis optica.
