Abstract

See full text

The present invention discloses small-size battery protection packages and provides a process of fabricating small-size battery protection packages. A battery protection package includes a first common-drain metal oxide semiconductor field effect transistor (MOSFET), a second common-drain MOSFET, a power control integrated circuit (IC), a plurality of solder balls, a plurality of conductive bumps, and a packaging layer. The power control IC is vertically stacked on top of the first and second common-drain MOSFETs. At least a majority portion of the power control IC and at least majority portions of the plurality of solder balls are embedded into the packaging layer. The process of fabricating battery protection packages includes steps of fabricating power control ICs; fabricating common-drain MOSFET wafer; integrating the power control ICs with the common-drain MOSFET wafer and connecting pinouts; forming a packaging layer; applying grinding processes; forming a metal layer; and singulating battery protection packages.
