    Abstract: A method for forming a semiconductor device structure is provided. The method includes forming an interconnect structure over a substrate. The method further includes forming a passivation layer over the interconnect structure. The method further includes forming a conductive structure over the passivation layer, wherein the conductive structure includes a surrounding portion over the passivation layer, and a concave portion surrounded by the surrounding portion. A height of the surrounding portion is greater than a height of the concave portion calculated from a top surface of the passivation layer. The method further includes forming a liner over the conductive structure, wherein an oxygen-to-silicon ratio of the liner is lower than about 1.8.
