Abstract: A method of fabricating a semiconductor structure is provided. A substrate surface is provided and a first layer is disposed on the substrate surface. A second layer covering the first layer is formed wherein the materials of the first layer and the second layer are different. A first polishing operation is performed on the second layer until a first polished surface exposing a portion of the first layer is obtained. A second polishing operation is performed on the first polished surface to obtain a second polished surface wherein an upper portion of the exposed portion of the first layer is removed. None of the substrate is exposed from the first polished surface and the second polished surface.
