Abstract
Semiconductor devices are provided. The semiconductor device includes a first dielectric layer, a bump, an etching stop layer and a spacer. The first dielectric layer is disposed over and exposes a conductive structure. The bump is partially disposed in the first dielectric layer to electrically connect the conductive structure. The etching stop layer is disposed over the first dielectric layer aside the bump. The spacer surrounds the bump and disposed between the etching stop layer and the bump.
