PROBLEM TO BE SOLVED: To provide a perpendicular magnetic tunnel junction structure and a magnetic element including it, and to provide a method of manufacturing the same. SOLUTION: The perpendicular magnetic tunnel junction includes a free layer in any one magnetic layer out of an upper magnetic layer and a lower magnetic layer. A polarization reinforcement layer and an exchange blocking layer are laminated between a tunneling layer and the free layer. The exchange blocking layer is an amorphous non-magnetic layer, and the polarization reinforcement layer is any one layer of an Fe layer, an Fe based alloy layer having a body-centered cubic (bcc) structure, a CoFeB based amorphous alloy layer, an L21 type Heusler alloy layer, and their composite layer. The amorphous non-magnetic layer is any one layer of a zirconium-based amorphous alloy layer, a titanium-based amorphous alloy layer, a palladium-based amorphous alloy layer, an alminium-based amorphous alloy layer, and their composite layer. The amorphous non-magnetic layer is an amorphous in whole and may have a nanocrystalline structure locally. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a method of manufacturing an integrated thin-film solar cell in which a non-effective area of the cell is reduced, which eliminates the need for turning over or cleaning of a substrate, and which does not expose the substrate to an atmosphere. SOLUTION: The method of manufacturing an integrated thin-film solar cell includes: a step of preparing a substrate on which trenches are separately formed at given intervals; a step of forming a first electrode layer on a portion of the bottom and one side face of each of the trenches using a first conductive material; a step of forming a solar cell layer on the first electrode layer and on a portion of the trench on which the first electrode layer is not formed; a step of obliquely vapor-depositing a second conductive material on the solar cell layer to form a second electrode layer; a step of etching the solar cell layer formed on the trenches such that the first electrode layer may be exposed; and a step of obliquely vapor-depositing a third conductive material on the second electrode layer to form a conductive layer such that the exposed first electrode layer and the second electrode layer may be electrically interconnected.

Abstract:
Provided are a phase change memory device that can operate at low power and improve the scale of integration by reducing a contact area between a phase change material and a bottom electrode, and a method for fabricating the same. The phase change memory comprises a current source electrode, a phase change material layer, a plurality of carbon nanotube electrodes, and an insulation layer. The current source electrode supplies external current to a target. The phase change material layer is disposed to face the current source electrode in side direction. The carbon nanotube electrodes are disposed between the current source electrode and the phase change material layer. The insulation layer is formed outside the carbon nanotube electrodes and functions to reduce the loss of heat generated at the carbon nanotube electrodes.

PROBLEM TO BE SOLVED: To provide an interaction device using kinesthetic feedback, and its operation method. SOLUTION: In the interaction device connected by mutual communication, each interaction device using kinesthetic feedback includes: a driving part which operates the interaction device in accordance with user's operation and generates kinesthetic feedback; a sensor which measures power applied to the driving part, physical quantity and pathway; a conversion part which converts an operation signal of a driving part measured by the sensor to an electrical signal for transmission; and a communication module for sending and receiving the electrical signal. Its operation method is also achieved. Consequently, it is also possible to transmit kinesthetic feedback by user's operation to a contact destination through a mobile terminal other than voices.
