摘要: A manufacturing process is applicable to singulating die from a substrate, where the substrate has layer distinguishable by mechanical property such as brittleness. The can include providing workpiece including and disposed on first surface, modifying compression, deforming region of proximate portion having modified property; fracturing at location deformed substrate. Also, propagating crack through line along layer. formed in this manner also provided.
