  • Patent number: 8791574
    Abstract: In a manufacturing method of a semiconductor device having a multilevel interconnect layer including a low-k layer, a two-step cutting technique is used for dicing. After formation of a groove in a semiconductor wafer with a tapered blade, the groove is divided with a straight blade thinner than the groove width. The multilevel interconnect layer portion is cut while being covered with a tapered face and then the wafer is separated with a thin blade which is not brought into contact with the multilevel interconnect layer portion. The wafer can thus be diced without damaging a relatively fragile low-k layer.
