A semiconductor package and a fabrication method thereof are provided, in which
a ground pad on a chip is electrically connected to a ground plane on a substrate
by means of an electrically-conductive wall formed over a side surface of the chip
and an electrically-conductive adhesive used for attaching the chip to the substrate.
Therefore, a wire-bonding process is merely implemented for power pads and signal
I/O (input/output) pads on the chip without having to form ground wires on the
ground pads for electrical connection purposes. This benefit allows the use of
a reduced number of bonding wires and simplifies wire arrangement or routability.
And, a grounding path from the chip through the electrically-conductive wall and
electrically-conductive adhesive to the substrate is shorter than the conventional
one of using ground wires, thereby reducing a ground-bouncing effect and improving
electrical performances of the semiconductor package.
