Abstract:
1. A method for forming a semiconductor package comprising: providing at least one die having active and inactive surfaces, wherein the active surface of the die includes a plurality of conductive die pads; providing a planar permanent carrier having first and second planar surfaces; attaching the at least one die to the second planar surface of the planar permanent carrier, wherein the inactive surface of the at least one die is facing the planar permanent carrier which supports the die during assembly; and forming a cap having first and second surfaces to encapsulate the at least one die, wherein the cap surrounds the at least one die without contacting the active surface of the at least one die, the second planar surface of the planar permanent carrier covers the inactive surface of the at least one die and the first surface of the cap, and the second surface of the cap is disposed at a different plane than the active surface of the die.
