Abstract:
1. A method of producing a semiconductor device comprising: a dicing step of dicing a wafer member using a dicing blade to form a cut portion in the wafer member, said wafer member being formed of a wafer portion, a glass substrate, and an adhesive layer for bonding the wafer portion and the glass substrate in a thickness direction of the wafer member so that the cut portion penetrates the wafer portion and the adhesive layer and reaches a part of the glass substrate; and an individual piece dividing step of applying a mechanical force to the wafer member so that the wafer member is divided into a plurality of semiconductor devices with the cut portion as a fracture initiation portion, wherein, in the individual piece dividing step, a bending force is applied to the wafer member as the mechanical force so that the cut portion substantially matches to a bending center point of the bending force.
