  • Patent number: 6629553
    Abstract: A semiconductor device mounting method and system and an IC card fabricating method which can fabricate high quality products by dicing a thin semiconductor wafer, in a state where it is adhered to an adhesive sheet, into thin semiconductor devices, peeling the group of diced thin semiconductor devices from the adhesive sheet at high speed without damaging or cracking the semiconductor devices, conveying the group of peeled semiconductor devices on a unit basis in serial order, and mounting them onto a mounting board.

  • Patent number: 6602736
    Abstract: In an apparatus for separating semiconductor chips, a semiconductor wafer stuck to an adhesive sheet with its silicon mirror surface facing downwards is sucked as a whole through its circuit surface side by means of a sucker plate capable of sucking the whole of wafer. In order to separate the sheet from a frame fixing the sheet while the sheet being sucked, the sheet is cut by a cutter edge so as to be separated from the frame. To separate the sheet from the wafer, the wafer top surface is guided by a guide plate having a tip angle of 15° and by causing the sheet to profile the tip of the guide plate, the sheet is peeled off in a direction making an angle of 45° to the dicing direction on the wafer.
