Abstract
A semiconductor device includes a semiconductor layer having a first surface and a second surface, a through electrode penetrating the semiconductor layer and having a protruding portion that protrudes over the second surface of the semiconductor layer, a front-side bump disposed on the first surface of the semiconductor layer and electrically coupled to the through electrode, a passivation pattern including a first insulation pattern that surrounds a sidewall of the protruding portion of the through electrode and extends onto the second surface of the semiconductor layer and a second insulation pattern that covers the first insulation pattern and has an etch selectivity with respect to the first insulation pattern, and a back-side bump covering an end surface of the protruding portion of the through electrode and extending onto the passivation pattern.
