Abstract

The present invention provides a machining apparatus that can solve the case of grinding the holding surface of a chuck table and the case of sucking and holding a wafer on the holding surface of the chuck table to perform the grinding process. non-constant problem. The machining apparatus includes a chuck table mechanism including a chuck table configured to hold the wafer and a table base configured to support the chuck table in a detachable manner. The chuck table includes a porous plate having a suction surface that sucks the wafer, a frame body surrounding surfaces of the porous plate other than the suction surface of the porous plate, a wafer suction hole formed in the frame body and configured to transmit a suction force to the suction surface of the porous plate, and a bolt hole formed in the frame body and configured to fix the frame body to the table base.

Description

technical field [0001] The present invention relates to a processing device comprising: a holding unit that suction-holds a wafer; a processing unit that has a rotatable grinding wheel that grinds the wafer held by the holding unit; and processing The liquid supply unit supplies the processing liquid to the wafer. Background technique [0002] The wafer divided by a plurality of intersecting dividing lines and formed with multiple devices such as IC and LSI on the front side is ground and processed to a desired thickness on the back side, and then divided into individual device chips by a dicing device and a laser processing device. The device chips obtained by dividing are used in electronic equipment such as mobile phones and personal computers. [0003] The grinding device has: a holding unit that attracts and holds the wafer; a processing unit that has a rotatable grinding wheel that grinds the wafer held by the holding unit; and a processing fluid supply unit that The...
