| Abstract: | The fracture of thin/ultra-thin silicon dies accounts for half of the failures of IC cards,and its failure modes and failure mechanism are not well understood then. The physical mechanismof die fracture is introduced and the impacts of the wafer thinning, dicing, ejector pin and mouldingprocesses of IC cards to the fracture of thin/ultra-thin silicon dies are investigated with regard to thearts and crafts and failure analysis of IC cards. |
