Problems solved by technology

As a result, there is a problem that it is more difficult to remove chips
[0010] Moreover, if the semiconductor chip divided by such a cutting device is moved directly to the subsequent process in a state where cutting chips are attached to the semiconductor chip, the cutting chips will fall on the circuit of the product and become a cause of product failure.

Abstract

The invention provides a cutting device which more surely prevents adhering of chips to the surface of a workpiece. This cutting device is provided with: a cutting blade, a cutting liquid supply means for supplying cutting liquid to the cutting blade and a machining point of the workpiece; and a blade cover arranged to cover an outer periphery of the cutting blade. The cutting device is further provided with a cutting chip control means oppositely arranged to hold the cutting blade on both spindle axial direction sides of the cutting blade to inject liquid toward a position separated by a prescribed distance from the machining point on the surface of the workpiece from both sides of the cutting blade. The cutting chip control means forms liquid walls along the cutting direction on both the sides of the cutting blade not to splash the chips generated by cutting the workpiece in the spindle axial direction by injecting the liquid, and separates the chips from the surface of the workpiece by a flow of the injected liquid.

Description

technical field [0001] The present invention relates to a cutting device, in particular to a cutting device capable of preventing cutting chips from adhering to the surface of a workpiece. Background technique [0002] For example, in the manufacturing process of semiconductor equipment, circuits such as ICs and LSIs are formed in a plurality of regions divided by grid-like blocks (cutting lines) formed on the surface of a roughly disc-shaped semiconductor wafer or other workpiece, and circuits such as ICs and LSIs are formed along the Semiconductor chips are fabricated as the blocks are divided to form the various regions of the circuit. The semiconductor chips thus manufactured are packaged and widely used in electrical equipment such as cellular phones and personal computers. [0003] As a dividing device for dividing such a workpiece such as a semiconductor wafer, a cutting device is generally used as a dicing device. This cutting device performs cutting by relatively ...
