Abstract: Provided is a method of forming a fine pattern using a block copolymer. The method comprises forming a coating layer including a block copolymer having a plurality of repeating units on a substrate. A mold is provided having a first pattern comprising a plurality of ridges and valleys. The first pattern is transferred from the mold into the coating layer. Then, a self-assembly structure is formed comprising a plurality of polymer blocks aligned in a direction guided by the ridges and valleys of the mold thereby rearranging the repeating units of the block copolymer within the coating layer by phase separation while the coating layer is located within the valleys of the mold. A portion of the polymer blocks are removed from among the plurality of polymer blocks and a self-assembly fine pattern of remaining polymer blocks is formed.

Abstract: For patterning during integrated circuit fabrication, an image layer is activated for forming a respective first type polymer block at each of two nearest activated areas. A layer of block copolymer is formed on the image layer, and a plurality of the first type polymer blocks and a plurality of second and third types of polymer blocks are formed on an area of the image layer between outer edges of the two nearest activated areas, from the block copolymer. At least one of the first, second, and third types of polymer blocks are removed to form a variety of mask structures.

Abstract: A photoacid generator represented by Formula 1 or Formula 2: wherein R1, R2, and R3 are each independently a C1-C10 alkyl group, X is a C3-C20 alicyclic hydrocarbon group forming a ring with S+, and at least one CH2 group in the alicyclic hydrocarbon group may be replaced with at least one selected from the group consisting of S, O, NH, a carbonyl group, and R5—S+A?, where R5 is a C1-C10 alkyl group, and A? is a counter-ion.

Abstract: A method of patterning a substrate includes processing first regions of the substrate to form a first pattern, the first regions defining a second region between adjacent first regions, arranging a block copolymer on the first and second regions, the block copolymer including a first component and a second component, the first component of the block copolymer being aligned on the first regions, and selectively removing one of the first component and the second component of the block copolymer to form a second pattern having a pitch that is less than a pitch of a first region and an adjacent second region.

Abstract: A method of processing information inputted while a mobile communication terminal is in an active communications state is provided. The method of processing information inputted while a mobile communication terminal is in an active communications state includes receiving information inputted while the mobile communication terminal is in an active communications state; displaying, if the active communications state is terminated before processing the inputted information, the unprocessed inputted information that exists; and processing the unprocessed inputted information. The inputted information can be input using various input modes such as a numeral, Korean character, English character, and special character input modes.

Abstract: A method of sharing information between mobile terminals using a local wireless communication network is disclosed. The method includes setting information stored in a first mobile terminal with one of at least two security levels; if registration is requested by a second mobile terminal, registering an identifier of the second mobile terminal and an access rights level of the second mobile terminal to the information set with a security level; if a local wireless communication link is formed with the second mobile terminal, displaying a list of information set with a set security level corresponding to the access rights level of the second mobile terminal; and sharing the displayed information according to a request from the second mobile terminal. According to the present invention, information stored in a mobile terminal may safely be shared with another mobile terminal in a local wireless communication area.

Abstract: Provided is a method for tracking a lost mobile station. The method includes, when a replacement Subscriber Identity Module (SIM) card is installed, determining whether the replacement SIM card is registered as a licensed replacement SIM card; when the SIM card is not registered, transmitting a previously stored tracking short message to a preset destination; and upon receipt of a tracking response short message, setting a tracking lock mode for limiting use of some functions of the mobile station.

Abstract: A mobile communication terminal and method for running an application therein. When a user inputs a variable in an idle state, variable-related applications are displayed. When the user selects a predetermined application, the input variable is input as an input value of a predetermined input field of the selected application.
