摘要: A method for dicing a semiconductor wafer includes the steps of: forming grooves in an integrated circuit layer of the semiconductor wafer; forming a photoresist layer on the integrated circuit layer; forming V-shaped first notches, each of which is further indented from the integrated circuit layer; thinning the substrate; attaching a blue tape to the integrated circuit layer; forming V-shaped second notches, each of which is indented from the thinned substrate and each of which is registered with a respective one of the first notches such that the first and second notches cooperatively define imaginary breaking lines, respectively; and pressing the blue tape at positions that are aligned with the imaginary breaking lines, respectively.
