A semiconductor packaging device has a carrier having at least a portion configured
for containing a chip. The chip, affixing to the portion with sidewall, has a back
surface an active surface, which multitudes of bonding pads are on the active surface.
One insulating layer on the active surface and carrier has multitudes of conductive
holes corresponding to the first bonding pads. A multi-layer structure on the insulating
layer is configured for providing electrical connection to the conductive holes.
Another insulating layer, affixed on one of the carrier and the multi-layer structure,
has another conductive holes electrically connected to the conductive holes. Multitudes
of solder balls, on at least one of the carrier and latter insulating layer, electrically
connect the latter conductive holes.
