Abstract:
The purpose of the present invention is to provide a method of manufacturing a semiconductor device, the method being capable of reducing a variation in the height of an active region of a fin by removing the unevenness of the thickness of an element isolation layer, wherein the unevenness is generated in a polarization process of the element isolation layer before a fin recess process. The method of manufacturing a semiconductor device includes forming a free element isolation layer covering a fin formed on a substrate, wherein the free element isolation layer includes a lower free element isolation layer in contact with the fin, and an upper free element isolation layer not in contact with the fin; removing a portion of the upper free element isolation layer through a first polishing process; and performing planarization for the free element isolation layer to place the upper surface of the fin and the upper surface of the free element isolation layer on the same plane through a second polishing process, in which the rest of the upper free element isolation layer is removed.

PURPOSE: A storage device for protecting content, a host device thereof, and a method thereof are provided to protect content providing a security information file by generating information for matching control information for controlling the use of encoded content as an independent security information file. CONSTITUTION: A secure area(310) stores an encoding key for decoding encoded content. The secure area permits the access of a host device authenticated through a safe authentication protocol. The secure area stores control information controlling the use of the encoded content and a security information file for matching the encoding key with the encoded content. The security information file includes an identifier for identifying the control information matched with the content, a storage location of a title key decoding the content, and a key number.

Abstract:
PURPOSE: A data veiling capable of using an ECC(Error-Correction Code), a detection method and an apparatus are provided to use the ECC in order to enhance the efficiency, instead of the previous data veiling and the detection method. CONSTITUTION: A method veiling the protection objective data in a memory comprises followings: a step(410) encoding the protection objective data by using the ECC; a progression inserting step(420) inserting the predetermined progression into the encoded data according to the determined rule; a step(430) combining the data in which the progression is inserted with the error; and a storing step(440) storing the error combined data in an arbitrary position among the total memory area.

Abstract:
PURPOSE: A method for providing a digital rights management service in a service providing device and a method which the digital rights management service is provided in the service providing device and a user terminal are provided to use various digital rights management systems provided from a server without a kind of the digital rights management system installed in the user terminal. CONSTITUTION: A server receives first digital rights management system information installed in user terminal. A database(150) stores a digital rights management server application generating a license and digital rights management proxy server agent software in a digital rights management system supported in a service providing device. A digital rights management system coordinator(145) compares a first digital rights management system installed in the user terminal with the digital rights management system of the service providing device based on the first digital rights management system information.

Abstract:
PURPOSE: A content protecting, a host device thereof, a storage device thereof, and a storage medium read by machinery are provided to safely authenticate the storage device by issuing intrinsic entity information and authentication information to various modules having different functions and performing independent authentication to the modules through the host device. CONSTITUTION: A first module authenticating unit(210) obtains first authentication information about a first module among modules in a storage device and authenticates the first module based on the first authentication information and intrinsic entity information of the first module. A second module authenticating unit(220) obtains second authentication information about a second module and authenticates the second module based on the second authentication information and intrinsic entity information of the second module. When the first and second modules are authenticated, an authentication coordinator(240) permits access to contents stored in the storage device.
Abstract:
PURPOSE: A storing device having an identifier, an authenticating method thereof, and an apparatus are provided to increase usability of a storing device. CONSTITUTION: An ID decoder(141) requests EID(Encoded ID) information in a storing unit and decodes the EID. An authenticating module(142) verifies individual ID information through ID authentication information. The ID information includes the individual ID information according to use of the storing unit.
