Abstract: Provided are a cleaning device and a method for driving the cleaning device which cleans a wafer after chemical mechanical polishing. The cleaning device includes a cleaning modules and a running beam, the running beam including a first blade and a second blade to insert or remove the wafer with respect to one of the cleaning modules in a second direction, the first blade and the second blade being fixed to the running beam and movable in the second direction, and the cleaning modules including an input module, a megasonic module, a first brush module, a second brush module and a drying module. The driving method includes performing an operation of inserting or removing the wafer in the second direction using the first blade in a first area; and performing an operation of inserting or removing the wafer in the second direction using the second blade in a second area.

Abstract: A film with codes, a reader configured to read the film, and an electronic device having a display including the film are provided. The reader may include a first light irradiating section, a second light irradiating section, a control section, and a light capturing section.

Abstract: Disclosed are a film having codes recorded thereon, a reader used to recognize the film having the codes recorded thereon, and electronic equipment including a display device to which the film having the codes recorded thereon is attached. The reader includes a light emitting part irradiating light having a first wavelength onto a film surface printed with a code by using a predetermined fluorescent material, and a light receiving part receiving only a light having a second wavelength radiated by the predetermined fluorescent material if the light having the first wavelength is irradiated on the code. The reader recognizes the codes together with a screen when a code pattern is printed on the surface of the transparent material and the transparent material is attached on the surface of a display part provided in the electronic equipment.
