Abstract
A method for forming a semiconductor structure is provided. The method includes forming an interconnect structure, and forming a conductive feature electrically connected to the interconnect structure. The method also includes forming a first passivation layer over the interconnect structure and the conductive feature, and etching the first passivation layer to form an opening that exposes the conductive feature. The method further includes performing an electrical test on the conductive feature, filling the opening with an oxide material, and attaching a carrier substrate over the oxide material using a bonding layer.
