Abstract:
A separation apparatus comprising a first and a second scribing devices for scribing front and rear surfaces of a first mother substrate made of a brittle material along first predetermined scribing lines previously provided on the front and rear surfaces of the first mother substrate, the first and second scribing devices being opposed to each other on an upper side and a lower side, and a holding and transferring device for holding and transferring the first mother substrate so that the first predetermined scribing lines of the first mother substrate are located between the first and second scribing devices.

PROBLEM TO BE SOLVED: To provide a wire saw which prevents a workpiece portion cut into a wafer shape from moving like bellows by slurries scattering in a wire cut-in part on the workpiece side, and dropping from the side of a workpiece holding part, and improves warp of sliced wafers.SOLUTION: The wire saw includes: at least a wire which is wound on a plurality of grooved rollers to reciprocate in an axial direction; a nozzle for supplying slurries; a backing plate; and a workpiece feeder which holds a workpiece via a backing plate and a workpiece plate holding the backing plate and feeds them to the wire. The wire-saw supplies the slurries from the nozzle while pressing the workpiece held by the workpiece feeder against the wire to make cut-in feed, and cuts it into a wafer shape. The workpiece feeder has a workpiece holding part, and the maximum width of a lower end of the workpiece holding part is larger than a width of the workpiece to be cut.

PROBLEM TO BE SOLVED: To prevent the adhesion of cutting powders to a back surface of a substrate fixing pallet, concerning the substrate fixing pallet and a substrate machining device suitably used for substrate machining by a router bit. SOLUTION: The substrate fixing pallet is provided with a pallet body 21 on which a substrate 41 to be machined is fixed, and equipped to a dust collecting device 10 sucking cutting powders generated during machining. On the pallet body 21, a ventilating passage 38 in which the sucking air of the dust collecting device 10 flows is formed. COPYRIGHT: (C)2010,JPO&INPIT
