Abstract: A semiconductor chip includes a semiconductor substrate including a bump region and a non-bump region, a bump on the bump region, and a passivation layer on the bump region and the non-bump region of the semiconductor substrate. No bump is on the non-bump region. A thickness of the passivation layer in the bump region is thicker than a thickness of the passivation layer in the non-bump region. The passivation layer includes a step between the bump region and the non-bump region.
