Publication number: US20220181174A1
Application number: 17/457,706

A wafer manufacturing apparatus includes an ingot grinding unit for grinding an upper surface of an ingot to planarize the upper surface of the ingot, a laser applying unit for forming peel-off layers in the ingot at a depth therein, which corresponds to the thickness of a wafer to be produced from the ingot, from the upper surface of the ingot, a wafer peeling unit for holding the upper surface of the ingot and peeling off a wafer from the ingot at the peel-off layers, a tray having an ingot support portion and a wafer support portion, and a belt conveyor unit for delivering the ingot supported on the tray between the ingot grinding unit, the laser applying unit, and the wafer peeling unit.

Application number: 17/457,090

A grinding method for grinding a workpiece by use of a grinding apparatus including a holding table that holds the workpiece by a holding surface, and a grinding unit that grinds the workpiece held by the holding table by a grinding wheel having a plurality of grindstones arranged in an annular pattern includes a groove forming step of grinding the workpiece by bringing the grindstones into contact with the workpiece to form the workpiece with an arcuate groove having a depth of less than a finished thickness of the workpiece, and a grinding step of bringing the grindstones into contact with a surface side of the workpiece where the groove is formed to grind the workpiece until the thickness of the workpiece becomes the finished thickness.

Application number: 17/455,993

A processing method of a wafer includes trimming the wafer along its outer peripheral edge while causing a cutting blade to cut from a front surface into a chamfered portion to a depth greater than a finish thickness, so that an annular stepped portion is formed in an outer peripheral surplus region. A protective member is bonded to a side of the front surface of the wafer, and the wafer is ground from its back surface to thin the wafer to a finish thickness. Between trimming and grinding, a laser beam is applied to the stepped portion, so that annular modified layers which are to be fractured under a pressing force to be applied by the grinding are formed in the stepped portion, whereby the fractured fragments of the stepped portion are subdivided.
