Claim 13:
14. The method of claim 12, wherein forming the redistribution circuit structure further comprises:
forming a first portion of a second metallization layer on the second end of the first metallization layer protruded out of the first dielectric layer;
disposing an inter-layer material to embed the first portion of the second metallization layer therein;
planarizing the inter-layer material to form an inter-layer film, wherein at least a portion of the first portion of the second metallization layer is protruded out of the inter-layer film, wherein an interface of the first dielectric layer and the inter-layer film is located at a sidewall of the first metallization layer;
forming a second portion of a second metallization layer on the first portion of the second metallization layer protruded out of the inter-layer film;
disposing a second dielectric material to embed the second portion of the second metallization layer therein; and
planarizing the second dielectric material to form a second dielectric layer, wherein at least a portion of the second portion of the second metallization layer is protruded out of the second dielectric layer, wherein an interface of the inter-layer film and the second dielectric layer is located at a sidewall of the first portion of the second metallization layer.
