Abstract:
There is provided a processing method for a package substrate having a plurality of division lines formed on the front side. The processing method includes the steps of holding the back side of the package substrate by using a holding tape and fully cutting the package substrate along the division lines to such a depth corresponding to the middle of the thickness of the holding tape by using a profile grinding tool, thereby dividing the package substrate into individual semiconductor packages. The profile grinding tool has a plurality of projections for cutting the package substrate respectively along the plural division lines. Each projection has an inclined side surface.

Claim (Index 3):
The substrate processing method according to  claim 1 , wherein said shaped abrasive member further has a cylindrical base having an abrasive grain layer on the outer circumferential surface thereof, and said projection projects radially outward from the outer circumferential surface of said cylindrical base in an amount set so that when said substrate is fully cut by said projection to the depth corresponding to the middle of the thickness of said holding tape or said holding jig, said abrasive grain layer formed on the outer circumferential surface of said cylindrical base comes into contact with the upper surface of each chip to thereby grind the upper surface of each chip, thereby reducing the thickness of each chip to a predetermined thickness.
