20100075162 | IMPLANTS COMPRISING BIODEGRADABLE METALS AND METHOD FOR MANUFACTURING THE SAME - The present invention provides an implant consisting of a biodegradable magnesium-based alloy or partially applied with the magnesium-based alloy, and a method for manufacturing the same. The implant according to the present invention is biodegradable, in which its biodegradation rate can be easily controlled, and the implant has excellent strength and interfacial strength to an osseous tissue. | 03-25-2010 |
20100173186 | ORGANIC ELECTROLYTE FOR LITHIUM-ION BATTERY AND LITHIUM-ION BATTERY COMPRISING THE SAME - Disclosed are an organic electrolyte for a lithium-ion battery and a lithium-ion battery comprising the same, wherein the electrolyte includes a base electrolyte containing a lithium salt dissolved in an organic solvent, and diphenyloctyl phosphate added thereto in an amount of 0.1 to 20 wt %. As compared to a conventional organic electrolyte using only a carbonate ester-based solvent, such as ethylene carbonate, ethyl methyl carbonate, etc., the lithium-ion battery employing the organic electrolyte can improve thermal stability of an electrolyte solution, high-rate performance, and charge/discharge cyclability of a battery, while maintaining battery performance of the base electrolyte. | 07-08-2010 |

20080220605 | METHOD OF MANUFACTURING FLASH MEMORY DEVICE - The present invention discloses a method of manufacturing a flash memory device comprising the steps of forming a first insulating layer and a first conductive layer on a semiconductor substrate; etching the first conductive layer, the first insulating layer and the semiconductor substrate to form a trench; forming an isolation layer on a region on which the trench is formed; forming a second conductive layer to make the second conductive layer contact with the first conductive layer; and removing the second conductive layer formed on the isolation layer. | 09-11-2008 |
20100304549 | METHOD OF FORMING ISOLATION LAYER OF SEMICONDUCTOR DEVICE - A method of forming an isolation layer of a semiconductor device includes forming first trenches in an isolation region of a semiconductor substrate. Sidewalls and a bottom surface of each of the first trenches are oxidized by a radical oxidization process to form a first oxide layer. An oxidization-prevention spacer is formed on the sidewalls of each of the first trenches. Second trenches are formed in the isolation region below the corresponding first trenches, wherein each second trench is narrower and deeper than the corresponding first trench. The second trenches are filled with a second oxide layer. The first trenches are filled with an insulating layer. | 12-02-2010 |

20100124669 | JOINING METHOD BETWEEN Fe-BASED STEELS AND Ti/Ti-BASED ALLOYS HAVING JOINT STRENGTH HIGHER THAN THOSE OF BASE METALS BY USING INTERLAYERS AND THE JOINTS PRODUCED USING THE METHOD - A joining method between Fe-based steel and Ti/Ti-based alloys having a joint strength higher than those of base metals by using interlayers. The production of intermetallic compounds at a joint portion between Fe-based steel and Ti/Ti-based alloys can be prevented using interlayers, and strong interface diffusion bonding can be formed at interfaces between interlayers, thereby producing a high-strength joint. Accordingly, the present disclosure can be used to develop high-strength, high-functional advanced composite materials. | 05-20-2010 |
