Abstract:
PROBLEM TO BE SOLVED: To provide a vertical type GaN light emitting element capable of improving characteristics of a horizontal type light emitting element by a metal protection film layer and a metal support layer.SOLUTION: A thick metal protection film layer 1100 of 10 micron or more is formed on the side surface and/or the lower surface of a vertical type GaN-LED, so that an element can be protected from an external impact and chip separation can be easily performed. And also, a metal substrate is used instead of a sapphire substrate so that heat that is generated at the time of element operation can be easily released, thereby suitable for use in a high output element. Thus, an element having improved optical output characteristics can be manufactured. A metal support layer 1900 is formed so that a phenomenon such that the element is distorted at the time of chip separation or damaged by an impact can be prevented. A p-type electrode 1200 is partially formed in a network on a p-GaN 1300, so that radiation of photon formed in an active layer 1400 toward an n-GaN layer 1500 can be maximized.

PROBLEM TO BE SOLVED: To provide a T-gate forming method for a high electron mobility transistor and a gate structure thereof. SOLUTION: The T-gate forming method for the high electron mobility transistor includes: a first step of coating a semiconductor substrate with a first, a second and a third resist, each having an electron beam sensitivity different from each other; a second step of performing a first exposure process by using an electron beam and then selectively developing the third resist; a third step of defining a gate head area 402 by selectively developing the second resist to have a developed width relatively wider than that of the selectively developed third resist; a fourth step of performing a second exposure process by using an electron beam on the semiconductor substrate having the third resist and second resist selectively developed and then selectively developing the first resist at a temperature relatively lower than in the development of the second and the third steps; and a fifth step of depositing metallic materials along the selectively developed resists and then removing them to form a T-gate having the gate head and a gate foot 404.

Abstract:
PROBLEM TO BE SOLVED: To provides peptides that stimulate release of arachidonic acid in target cells and peptides inducing release of calcium in cells. SOLUTION: The present inventors have identified 24 peptides that participate in arachidonic acid release in neutrophil-like differentiated HL60 (dHL60) cells, and found that these peptides act as chemotactic substances for human phagocytes. Several peptides binds to the formyl peptide receptor-like 1 (FPRL1). Some of the peptides are also bound to other receptor(s) expressed in HL60 cells. In addition, each peptide can stimulate shared and distinct intracellular signaling pathways. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a nanoporous tungsten carbide catalyst that can be used as an electrode of a fuel cell, and a preparation method thereof. SOLUTION: Provided are the nanoporous tungsten carbide catalyst, which includes tungsten carbide crystalline particles and has nanopores of a mean pore diameter ranging from 2 nm to 5 nm and a nanopore volume of 0.08 to 0.25 cm 3 per gram of the catalyst, the preparation method thereof, an electrode and a fuel cell, such as a direct methanol fuel cell and a polymer electrolyte membrane fuel cell, to which the nanoporous tungsten carbide catalyst is applied. The nanoporous tungsten carbide catalyst has high electrochemical activity and enhanced resistance to poisoning by carbon monoxide. This catalyst can keep high activity even when used as the electrode of the fuel cell for a long period of time. Since this catalyst has a wide surface area, a metallic active component can be dispersed suitably in this catalyst and consequently a metallic active component-supported catalyst can exhibit higher catalytic activity even when the metallic active component of the amount smaller than that of the conventional noble metal catalyst is supported. The electrode and the fuel cell employing this catalyst can be manufactured at lower costs, respectively. COPYRIGHT: (C)2008,JPO&INPIT
