A pellicle frame is mechanically attached to a reticle, without use of an adhesive. An embodiment includes mechanically attaching a pellicle frame to a front surface of a reticle, removing the pellicle frame from the reticle, cleaning the reticle, and mechanically reattaching the pellicle frame to the reticle. Embodiments further include using a clamp to mechanically attach the pellicle frame to the reticle. Embodiments further include forming the pellicle frame with a flange having an opening in the center, and forming the clamp with two portions, one portion with a protrusion that fittingly engages the opening in the flange and with a second opening, and the second portion with a segment that extends behind the reticle and with a second protrusion that fittingly engages the second opening. |
