Embodiment Construction

[0013] Hereinafter, preferred embodiments of the cutting device according to the present invention will be described in further detail with reference to the drawings.

[0014] figure 1 A perspective view of a cutting device constructed in accordance with the present invention is shown in . figure 1 The cutting device shown has a substantially cuboid device housing 2 . In the device case 2, a chuck table 3 as a workpiece holding member for holding a workpiece is arranged so as to be movable in a direction indicated by an arrow X (X-axis direction) which is a cutting feed direction. The chuck table 3 has a suction chuck support table 31 and a suction chuck 32 arranged on the suction chuck support table 31, and the suction chuck 32 is placed on top of the suction chuck 32 by operating a suction member (not shown). The holding surface of the surface attracts and holds the workpiece. In addition, the chuck table 3 is configured to be rotatable by a not-shown rotation mechanism. ...

Abstract

Provided is a cutting device capable of recovering cutting water supplied to a cutting portion of a cutting tool by a cutting member and regenerating it into water that does not damage a workpiece. The cutting device includes: a workpiece holding member that holds a workpiece; a cutting member that has a rotatable cutting blade that cuts the workpiece held on the workpiece holding member; A water supply mechanism that supplies cutting water to a cutting portion of a cutting tool based on a cutting member, the cutting device having: a cutting water receiving member that receives cutting water supplied to a cutting portion of a cutting tool based on a cutting member; A chip removing member removes chips mixed in the cutting water received by the cutting water receiving member; and a pump sends the cutting water from which chips have been removed by the chip removing member to the cutting water supply mechanism.

Description

technical field [0001] The present invention relates to a cutting device for cutting a workpiece such as a semiconductor wafer. Background technique [0002] In the manufacturing process of a semiconductor device, a plurality of regions are divided by dividing lines formed in a grid on the front surface of a substantially disk-shaped semiconductor wafer, and devices such as ICs and LSIs are formed in the divided regions. Individual semiconductor devices are manufactured by cutting the semiconductor wafer formed with a plurality of devices in this manner along planned dividing lines to divide regions where the devices are formed. [0003] A cutting device for cutting a semiconductor wafer along a planned dividing line includes: a workpiece holding member that holds a workpiece; cutting the workpiece on the surface; a cutting water supply member, which supplies cutting water to the cutting part of the cutting tool based on the cutting member; and a processing feed member, whi...
