20120137369 | MOBILE TERMINAL WITH SECURITY FUNCTIONALITY AND METHOD OF IMPLEMENTING THE SAME - Disclosed herein is a mobile terminal with security functionality and a method of implementing the mobile terminal. The mobile terminal with security functionality includes a storage unit, a first module, a second module, and a third module. The storage unit stores a list of risky function combinations which may cause security risks. The first module monitors functions included in an application to be installed or running in the mobile terminal. The second module assesses security vulnerabilities based on whether a combination of the monitored functions corresponds to a risky function combination and/or security attributes of the mobile terminal. The third module takes countermeasures when a security vulnerability has been found based on the assessment. | 05-31-2012 |
20120137372 | APPARATUS AND METHOD FOR PROTECTING CONFIDENTIAL INFORMATION OF MOBILE TERMINAL - Disclosed herein is an apparatus for protecting the confidential information of a mobile terminal. The apparatus for protecting the confidential information of a mobile terminal includes a storage unit and a confidential information management unit. The storage unit stores at least one piece of confidential information which requires security. The confidential information management unit moves the confidential information from the preset unsecured initial storage area of the storage unit, to the preset secured storage area of the storage unit and stores the confidential data in the preset secured storage area, in order to protect the confidential data, and exclusively manages the secured storage area. The secured storage area is set by the confidential information management unit. | 05-31-2012 |

20090165713 | CHEMICAL VAPOR DEPOSITION APPARATUS - Provided is a chemical vapor deposition apparatus. The apparatus includes a reaction chamber, a gas introduction unit, and a gas exhaust unit. The reaction chamber includes a susceptor on which a wafer is loaded and a reaction furnace in which the wafer is processed by chemical vapor deposition. The gas introduction unit is disposed at an outer wall of the reaction chamber to supply reaction gas from an outside of the reaction furnace to a center portion of the reaction furnace. The gas exhaust unit is disposed at a center portion of the reaction chamber to discharge the reaction gas to an upper or lower outside of the reaction chamber after the reaction gas is used for a reaction in the reaction furnace. Therefore, the gas density inside the chamber can be kept at a substantially uniform state even when process pressure is increased for growing a high-temperature deposition layer. | 07-02-2009 |

20090260572 | CHEMICAL VAPOR DEPOSITION APPARATUS - There is provided a chemical vapor deposition apparatus including: a chamber including a reactor where a deposition object is deposited; a first supplier including a plurality of gas pipes allowing a first gas to be jetted into the reactor in a substantially horizontal direction; a second supplier including a plurality of holes of a predetermined size having the gas pipes inserted therein, respectively; a supply flow path formed between each of the gas pipes and each of the holes, the supply flow path allowing a second gas to be supplied into the reactor in a substantially horizontal direction. | 10-22-2009 |
20090277387 | SUSCEPTOR AND CHEMICAL VAPOR DEPOSITION APPARATUS INCLUDING THE SAME - There are provided a susceptor and a chemical vapor deposition apparatus including the same. The susceptor includes: at least one pocket accommodating a deposition object therein; a seating part stepped downward from a top end of the pocket, the seating part having the deposition object placed thereon; and a recess recessed from the seating part to a predetermined depth, wherein the recess has a radius of curvature ranging from substantially 8000 mm to 25000 mm. | 11-12-2009 |
20100126419 | SUSCEPTOR FOR CVD APPARATUS AND CVD APPARATUS INCLUDING THE SAME - Provided are a susceptor and a chemical vapor deposition (CVD) apparatus including the susceptor. The susceptor has a simple structure and is configured to prevent bending of a substrate for uniformly heating the substrate and maintain wavelength uniformity of an epitaxial layer formed on the substrate. | 05-27-2010 |
20100175620 | CHEMICAL VAPOR DEPOSITION APPARATUS - A chemical vapor deposition apparatus includes a substrate ceiling unit forming a reaction chamber to which a reaction gas is supplied to epitaxially grow a substrate, and an exhaust unit separated from the substrate ceiling unit and serving to discharge an exhaust gas after epitaxial growth reaction. The exhaust unit includes a particle formation part to which particles generated in the epitaxial growth of the substrate are attached. | 07-15-2010 |
