Patent ID: 8703539

Claim:
A method for constructing an interposer assembly, comprising the steps of: mounting at least one conductive interposer stud on a conductive mounting plate; molding a carrier plane around the at least one interposer stud, such that at least a first surface of the mounting plate is outside the carrier plane and at least a second surface of the mounting plate is in contact with a first surface of the carrier plane; forming a first redirection layer on the first surface of the carrier plane, the redirection layer in electrical contact with at least one interposer stud; attaching at least a portion of at least a first integrated circuit die to at least a portion of the first redirection layer such that the first integrated circuit die is in signal communication with at least one interposer stud; forming a second redirection layer on the second surface of the carrier plane; attaching at least a portion of a second integrated circuit die to at least a portion of the second redirection layer such that the second integrated circuit die is in signal communication with at least one interposer stud; and attaching at least one first interlevel connection structure to at least a portion of the first redirection layer such that at least one first interlevel connection structure is in signal communication with at least one interposer stud, and wherein the first interlevel connection structure is configured to hold the interposer assembly mounted at a first separation distance from a target carrier board.
