Next, in FIG. 10, a dicing process is performed to separate the PoP packages 500 (e.g., 500A, 500B) into a plurality of individual PoP packages. In an exemplary embodiment, a blade 315 with a width of W₃ is used to dice the PoP packages. The width W₃ is smaller than the width W₂ measured between the sidewall 311E of the opening 311 and the sidewall 313E of the opening 313, in some embodiments. In the illustrated embodiment, the blade 315 is positioned in a center region between the sidewall 311E and the sidewall 313E, and therefore, does not overlap or contact the sidewalls 311E/313E during the dicing process. In other words, the blade 315 is laterally between the sidewall 311E and the sidewall 313E. In some embodiments, the width W₃ of the blade 315 is wider than the width W₄ of the remaining portion 140R of the redistribution structure 140′ disposed between the openings 311 and 313. This may allow the blade 315 to remove the remaining portion 140R in one cut to reduce the processing time of the dicing process. For example, the remaining portion 140R of the redistribution structure 140′ may be laterally between opposing vertical sidewalls of the blade 315, such that as the blade 315 cuts downward toward the redistribution structure 140′, the remaining portion 140R is removed in one cut.
