Abstract
A substrate having a first side and a second side opposite the first side is processed by providing a protective film having a front surface and a back surface opposite the front surface and providing a holding frame for holding the substrate. The holding frame has a central opening. The holding frame is attached to the back surface of the protective film so as to close the central opening of the holding frame by the protective film, and the first side of the substrate or the second side of the substrate is attached to the front surface of the protective film. The substrate is processed from the side of the substrate which is opposite the side of the substrate attached to the front surface of the protective film, and/or the side of the substrate which is attached to the front surface of the protective film.
