Abstract: In a method of forming a pattern using a composition for removing photoresist, a layer is formed on a substrate, and then a photoresist pattern is formed on the layer. A portion of the layer exposed by the photoresist pattern is etched using the photoresist pattern as an etching mask to form the pattern on the substrate. Then, the photoresist pattern is removed using the composition including hydroxylamine, an alkanolamine-based compound, a morpholine-based compound, a polar solvent, a corrosion preventing agent, and water. The composition may effectively remove a photoresist pattern and etched residues without damaging the substrate and/or the pattern including metal, nitride, oxide and/or metal nitride.

Abstract: A method of entering and modifying user data of a mobile communication terminal in a physically remote manner is provided A call is made from a mobile communication terminal to a computer or from a computer to a mobile communication terminal. Here, if a typical voice call or a simple data service call is connected, necessary data cannot be entered into the right memory area of the mobile communication terminal where said data have to be stored. In the present invention, a separate remote data update mode is set up and data and commands for transmission and entry of data are transmitted and received in this mode. According to the present invention, such data which cannot be entered by users in a direct manner to a mobile communication terminal as animation data or image data which are used for display on mobile communication terminal screen, melody data which are used for a ring tone for mobile communication terminal, game programs which are useable in mobile communication terminal, etc.
