Abstract:
1. A method for packaging a microelectronic substrate, comprising: providing a microelectronic substrate having a first surface, a second surface facing opposite from the first surface, and a plurality of first connection sites at least proximate to the first surface; disposing flowable, electrically conductive couplers at the first connection sites; disposing a generally non-conductive material between the conductive couplers; selecting a gap dimension based on a target underfill material flow rate; removing at least a portion of the generally non-conductive material to form a gap between neighboring conductive couplers, the gap having the selected gap dimension in a direction generally normal to the first surface of the microelectronic substrate; connecting the microelectronic substrate to a support member by attaching the conductive couplers to second bond sites of the support member; and flowing an underfill material into the gap at at least approximately the target underfill material flow rate.
