A unit semiconductor chip and stacked semiconductor package and method of
manufacturing with center bonding pads and at least one circuit layer to
reduce the length of bonding. The unit semiconductor chip includes a
first series of bonding wires connected to a plurality of center bonding
pads of a semiconductor chip, at least one circuit layer connected to the
first series of bonding wires and including a series of circuit layer
wiring patterns, and a second series of bonding wires connecting the
series of circuit layer wiring patterns and a series of wiring patterns.
The stacked semiconductor package further includes a second series of
wiring patterns, connected to the first series of wiring patterns, the a
second series of wiring patterns and the series of circuit layer wiring
patterns providing connections to adjacent lower and upper unit
semiconductor packages, respectively.
