ABSTRACT:
An incrementally continuous cleaving system allows for sequential flow of "material-to-be-cleaved" through a cleaving apparatus. In particular, a continuous feed tape membrane is used to support sequentially loaded optical bars (or, perhaps, wafers) that are then transported into a cleaving apparatus. The tape is advanced in small increments so that individual cleaving operations are performed at each scribe mark location on the top surface of the optical material. A vacuum pen (assisted by a detach pin) is then used to remove the cleaved section from the cleaving system. A conventional pick-and-place device may be used in the first instance to continuously load the bars (or wafers) onto the tape membrane.
