A chemical mechanical polishing method includes providing a device layer having a surface to be polished, polishing the surface using an alkaline grinding slurry, removing a residual layer that is been formed on the polished surface using an acid buffer, forming a passivation layer covering the polished surface of the device layer after the residual layer has been removed, and cleaning the passivation layer using deionized water. A semiconductor device thus fabricated has surfaces with excellent flatness, good manufacturing yield and long-term reliability.
