Abstract: Embodiments of the present disclosure provide a method of manufacturing a mask, a mask and an evaporation method with a mask. The method comprises: providing a frame and a mask body; and fixing the mask body to the frame to form the mask in a case where at least one of the mask body and the frame is at a predetermined temperature, such that the mask body is elastically deformed by a predetermined amount by tensioning the mask body by the frame by a thermal deformation at a usage temperature different from the predetermined temperature.
