Abstract

An integrated circuit includes a semiconductor substrate, contact pads, testing pads, conductive posts, dummy posts, and a protection layer. The contact pads and the testing pads are distributed over the semiconductor substrate. The conductive posts are disposed on the contact pads. The dummy posts are disposed on the testing pads and are electrically floating. The protection layer covers the conductive posts and the dummy posts. A distance between top surfaces of the conductive posts and a top surface of the protection layer is smaller than a distance between top surfaces of the dummy posts and the top surface of the protection layer.
