Claim Text:
1. A packaging substrate, comprising: an interposer having opposing first and second surfaces and a plurality of conductive gels interconnecting the first surface and the second surface, wherein each of the conductive gels has opposing first and second ends, such that the first end protrudes from the first surface of the interposer, and a circuit redistribution structure is disposed on the second surface of the interposer and electrically connected to the second ends of the conductive gels; an encapsulating layer that encapsulates and is in direct contact with side surfaces and the first surface of the interposer; and a circuit built-up structure disposed on the encapsulating layer above the first surface of the interposer and electrically connected to the first ends of the conductive gels.
