发明名称 REWORKABLE CHIP STACK
摘要 A method for removing a thinned silicon structure from a substrate, the method includes selecting the silicon structure with soldered connections for removal; applying a silicon structure removal device to the silicon structure and the substrate, wherein the silicon structure removal device comprises a pre-determined temperature setpoint for actuation within a range from about eighty percent of a melting point of the soldered connections to about the melting point; heating the silicon structure removal device and the soldered connections of the silicon structure to within the range to actuate the silicon structure removal device; and removing the thinned silicon structure. Also disclosed is a structure including a plurality of layers, at least one layer including a thinned silicon structure and solder coupling the layer to another layer of the plurality; wherein the solder for each layer has a predetermined melting point.
