Claim 12:
13. A semiconductor package, comprising:
a die, having a first center axis;
a redistribution structure disposed below and electrically connected to the die, comprising a plurality of conductive patterns and a plurality of conductive vias; and
a plurality of under-ball metallurgy (UBM) patterns, the plurality of conductive vias disposed between and in direct with the plurality of conductive patterns and the plurality of UBM patterns, wherein one of the plurality of conductive vias has a second center axis, a respective one of the plurality of UBM patterns under the one of the plurality of conductive vias has a third center axis, and a distance between the second center axis and the first center axis is larger than a distance between the third center axis and the first center axis.
