Patent ID: 7348215

Claim:
A method of assembling a flip chip semiconductor device assembly, the method comprising: providing at least one semiconductor die having an active surface and a back surface, the active surface having a plurality of conductive bumps protruding transversely therefrom; providing an interposer substrate having a first surface and a second surface, the first surface having a plurality of recesses therein, each extending to expose at least a portion of an elongated conductive element and configured for receiving one respective conductive bump of the plurality of conductive bumps; disposing a non-solid conductive material on each of the plurality of conductive bumps; and placing the at least one semiconductor die with the active surface facing the first surface of the interposer substrate and disposing each of the plurality of conductive bumps protruding transversely from the active surface of the at least one semiconductor die into a recess of the plurality of recesses of the interposer substrate so that each of the plurality of conductive bumps is substantially completely received within one of the plurality of recesses in the interposer substrate.
