Abstract: An extreme ultraviolet exposure system includes an exposure chamber having an internal space, upper and lower electrostatic chucks, a power supply, a light source, and a mask. The upper electrostatic chuck includes first and second electrodes that are adjacent to one another and that generate an electric field of different polarities, respectively, to provide an electrostatic force. The mask is attachable to the lower surface of the upper electrostatic chuck by the electrostatic force. The mask has a metal thin film pattern including a first region in which a metal thin film that shields the electric field, and a second region in which the metal thin film is not disposed and through which the electric field is transmitted. When the mask is attached, the electric field transmitted through the second region applies an attractive force or a repulsive force to charged particles in the exposure chamber.
