Classification: CPC H | IPC H

Claim 14:
15. The method of claim 14, wherein forming the redistribution circuit structure further comprises:
forming a first seed layer prior to forming the first metallization layer, wherein the first metallization layer is electrically coupled to the semiconductor die through the first seed layer;
forming a second seed layer prior to forming the first portion of the second metallization layer, wherein the first portion of the second metallization layer is electrically coupled to the first metallization layer through the second seed layer; and
forming a third see layer prior to forming the second portion of the second metallization layer, wherein the second portion of the second metallization layer is electrically coupled to the first portion of the second metallization layer through the third seed layer,
wherein a thickness of the third seed layer is greater than a thickness of the first seed layer and a thickness of the second seed layer.
