Claim:
1. A method comprising: providing a reusable carrier having a first surface and a second surface; disposing a die-bonding adhesive layer on the reusable carrier first surface; placing at least one magnetic holding structure proximate the reusable carrier second surface; providing at least one microelectronic die having an active surface and an opposing back surface with at least one sidewall extending therebetween and having a plurality of interconnection structures extending from the microelectronic die active surface, wherein the at least one microelectronic die includes at least one dummy magnetic column disposed on at least one of the microelectronic die active surface and the microelectronic die back surface; aligning the at least one microelectronic die with a magnetic force between the at least one magnetic holding structure and the at least one microelectronic die dummy magnetic columns; adhering the plurality of interconnection structures to the die-bonding adhesive layer; disposing an encapsulant material over the at least one microelectronic die; attaching a backside carrier to the encapsulant material with an adhesive layer; and removing the reusable carrier and the die-bonding adhesive layer.
