Claim Text:
1. A substrate comprising: a body including a first surface and a second surface opposite to each other, wherein the body includes a first film; at least one first wiring pattern disposed on the first surface of the body to include a bonding finger; a vent hole penetrated from the first surface of the body to the second surface of the body; an upper insulating pattern disposed on the first surface of the body to cover the overall surface of the at least one first wiring pattern except the bonding finger, wherein the upper insulating pattern includes a second film; a second wiring pattern disposed on the second surface of the body; a lower insulating pattern disposed on the second surface of the body to substantially cover the second wiring pattern, wherein the lower insulating pattern includes another second film; a first via electrode penetrating the body from the first surface to the second surface and coupling the at least one first wiring pattern to the second wiring pattern; a second via electrode penetrating the upper insulating pattern to contact the first wiring pattern; a first conductive layer pattern disposed on the upper insulating pattern to contact the second via electrode; a third via electrode penetrating the lower insulating pattern to contact the second wiring pattern; and a ball land pad disposed on a surface of the lower insulating pattern opposite to the body to contact the third via electrode.
