Abstract:
1. A method for producing a die assembly comprising: providing a wafer stack having a first wafer and a second wafer arranged in an overlying relationship with each other, a first portion of the first wafer supporting a first component, a second portion of the first wafer supporting a second component, the first component and the second component being located between the first wafer and the second wafer; exposing the first portion and the second portion of the first wafer by removing a portion of the second wafer; and dicing the first wafer between the first component and the second component to form a first die assembly and a second die assembly, the first die assembly including the first portion of the first wafer that extends outwardly beyond the periphery of a first portion of the second wafer, and the second die assembly including the second portion of the first wafer that extends outwardly beyond the periphery of a second portion of the second wafer such that neither the first component nor the second component is located between the first wafer and the second wafer; wherein the wafer stack includes a third wafer, the second wafer being arranged at least partially between the first wafer and the third wafer; and wherein exposing a portion of the first wafer comprises: exposing the first portion and second portion of the first wafer by removing a portion of the third wafer and the portion of the second wafer.
