Claim 17:
18. A redistribution substrate comprising:
a first conductive pattern;
a first via connected to a top surface of the first conductive pattern, the top surface of the first conductive pattern and a lateral surface of the first via are substantially perpendicular;
a first dielectric layer that encapsulates the first conductive pattern and the first via;
a second conductive pattern on the top surface of the first via, the second conductive pattern including:
a second conductive pattern pad connected to the first via, and
a plurality of connection lines spaced apart from the second conductive pattern pad;

a second via connected to a top surface of the second conductive pattern pad, the top surface of the second conductive pattern pad and a lateral surface of the second via are substantially perpendicular;
a second dielectric layer that encapsulates the second conductive pattern and the second via on the first dielectric layer; and
an under bump pad on the second via,
wherein the first dielectric layer is in direct contact with the lateral surface of the first via.
