Abstract:
A method for cleaving a semiconductor structure into subsections, the structure being provided with scribe marks defining a dimension of the subsections, said method comprising the steps of:transporting a plurality of the structures between elongated, opposed upper and lower sheets of flexible material in a direction generally perpendicular to the scribe marks, the structures being aligned along the length of the sheets with their scribe marks extending laterally of the sheets, the sheets being supported on a stabilizing surface to prevent their vibration;passing a leading edge of the structure over a raised, stationary breaker assembly, one of said sheets being in contact with the stabilizing surface beyond the breaker assembly in the direction of transportation;directing an air stream at said leading edge from above, whereby a subsection defined by the leading edge and one of the scribe marks is separated from the structure along said one scribe mark.
