Abstract
A system for manufacturing free-standing films from work pieces. The system includes a racetrack structure being configured to transfer at least one work piece and one or more accelerator-based ion implanters coupled to the racetrack structure via an end station. Each of the accelerator-based ion implanters is configured to introduce particles having an energy of greater than 1 MeV to implant into a surface of the work piece loaded in the end station to form a cleave region in the work piece. The system includes one or more cleave modules coupled to the racetrack structure configured to perform a cleave process to release a free-standing film from the work piece along the cleave region. Additionally, the system includes an output port coupled to each cleave module to output the free standing film detached from the work piece and one or more service modules each connected to the racetrack structure.
