Abstract
A semiconductor device may include a substrate including a first surface and a second surface, a through electrode penetrating the substrate to include a protrusion that protrudes from the second surface of the substrate, and a front side bump electrically coupled to the through electrode and disposed on the first surface of the substrate. The semiconductor device may include a first passivation pattern disposed on the first surface of the substrate to substantially surround a sidewall of the front side bump and may be formed to include an uneven surface, and a second passivation pattern disposed on the second surface of the substrate to include an uneven surface. The protrusion of the through electrode may penetrate the second passivation pattern to protrude from the uneven surface of the second passivation pattern.
