Abstract

A stackable ball grid array (BGA) or fine ball grid array (FBGA) semiconductor package particularly suitable for board-on-chip or chip-on-board applications in which a low profile BGA or FBGA semiconductor package is needed. The stackable ball grid array (BGA) or fine ball grid array (FBGA) provides a semiconductor package that is capable of being burned in and tested in a more efficient and cost effective manner than prior known BGA or FBGA semiconductor packages. A high density, low profile memory module incorporating a plurality of the disclosed BGA or FBGA semiconductor packages in a stacked arrangement is further disclosed.
