Abstract: An operation method and an electronic device thereof is provided. The electronic device includes a touchscreen, and a controller. A pressure of a touch input made to the touchscreen of the electronic device is detected. A crop mode is set based on an association between the crop mode and the pressure. A crop boundary is designated by the touch input according to the set crop mode.

Abstract: A composition for copper plating and associated methods, a method of forming a copper wiring including forming an insulation layer having a recessed portion on a substrate, and forming a copper layer on the insulation layer to fill the recessed portion by performing an electroplating process using a composition that includes an aqueous electrolyte solution containing a copper ion and at least one of a disulfide compound represented by Formula 1, a betaine compound represented by at least one of Formulae 3 and 4, and a triblock copolymer of polyethylene oxide-polypropylene oxide-polyethylene oxide (PEO-PPO-PEO) having a weight average molecular weight of about 2,500 to about 5,000 g/mol and an ethylene oxide content (EO %, w/w) of about 30% to about 60%.
