Abstract
Cleave systems for cleaving a semiconductor structure are disclosed. The cleave systems may include a cleave arm that is moveable from a starting position to a raised position in which a cleave stress is applied to the semiconductor structure. Spring members store energy as the cleave arm is raised with the stored spring energy causing the structure to cleave into two pieces upon initiation of the cleave across the structure.
