Patent ID: 8350361

Claim:
A semiconductor element having a conductive via, comprising: a silicon chip, comprising: a silicon substrate, having a first surface, a second surface and at least one through hole, the at least one through hole penetrating the silicon substrate; an active circuit layer, disposed on the second surface of the silicon substrate, and having at least one metal layer and an opening, the position of the opening corresponding to the through hole of the silicon substrate, and the opening exposing part of the metal layer; and at least one conductive via, penetrating the silicon substrate, and comprising: a first insulation layer having a thickness between 10 μm to 20 μm, disposed on a sidewall of the through hole and defining a first central groove; and a conductive metal, disposed in the first central groove and the opening of the active circuit layer, electrically connected to the metal layer of the active circuit layer, and a surface of the conductive metal exposing to outside of the first surface of the silicon substrate.
