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 1):
A substrate processing method for dividing a substrate along a plurality of division lines formed on the front side of said substrate to obtain individual chips and simultaneously providing a desired shape on each chip, said substrate processing method comprising:\n a holding step of holding the back side of said substrate by using a holding tape or a holding jig; and a dividing step of fully cutting said substrate along said division lines to such a depth corresponding to the middle of the thickness of said holding tape or said holding jig by using a shaped abrasive member after performing said holding step, thereby dividing said substrate into said individual chips; said shaped abrasive member having a projection for cutting said substrate, said projection having an inclined side surface or a vertical side surface with a step portion; said dividing step including the steps of cutting said substrate along each division line by using said projection to thereby divide said substrate into said individual chips and simultaneously forming an inclined side surface or a stepped side surface on each chip according to said inclined side surface or said vertical side surface with said step portion of said projection, wherein said inclined side surface or said stepped side surface on each chip is formed so that the lower surface of each chip becomes larger than the upper surface of each chip.
