- FIG. 1 is a plan view of the workpiece 1 during laser processing
- Fig. 2 is a cross-sectional view along the II-II line of the workpiece 1 shown in Fig. 1
- Fig. 3 is the workpiece after laser processing
- Fig. 4 is a cross-sectional view of the workpiece 1 shown in Fig. 3 along the IV-IV line
- Fig. 5 is a cross-sectional view of the workpiece 1 shown in Fig. 3 along the V-V line.

- the modified region 7 is formed by irradiating the processing object 1 with the laser beam L by aligning the condensing point P inside the processing object 1 under the condition that multiphoton absorption occurs. .
- the condensing point is a portion where the laser beam L is condensed.
- the condensing point P is moved along the planned cutting line 5 by relatively moving the laser beam L along the planned cutting line 5 (that is, along the direction of arrow A).
- the modified region 7 is formed only inside the workpiece 1 along the planned cutting line 5, and in this modified region 7, the cutting start region (scheduled cutting portion) is formed. 8 is formed.
- the laser processing method according to the present embodiment does not form the modified region 7 by causing the processing object 1 to generate heat by causing the processing object 1 to absorb the laser beam L.
- the modified region 7 is formed by transmitting the laser beam L through the workpiece 1 and generating multiphoton absorption inside the workpiece 1. Therefore, since the laser beam L is hardly absorbed by the surface 3 of the workpiece 1, the surface 3 of the workpiece 1 is not melted.
- the workpiece 1 When cutting the workpiece 1, if there is a starting point at the part to be cut, the workpiece 1 Therefore, the workpiece 1 can be cut with a relatively small force as shown in FIG. Therefore, the workpiece 1 can be cut without causing unnecessary cracks on the surface 3 of the workpiece 1.
- the following two types of cutting of workpieces starting from the cutting start region can be considered.
- One is a case where after the cutting start region is formed, an artificial force is applied to the processing target, so that the processing target is cracked from the cutting start region and the processing target is cut. This is, for example, cutting when the thickness of the workpiece is large.
- Artificial force is applied when, for example, bending stress or shear stress is applied to the workpiece along the cutting start area of the workpiece, or thermal stress is generated by applying a temperature difference to the workpiece. It is to let you.

- the cutting start region is formed by one row of modified regions.
- the thickness direction This is made possible by forming the cutting start region by the modified regions formed in a plurality of rows. Even in the case of natural cracking, the crack does not run on the surface of the portion corresponding to the portion where the cutting start region is not formed at the portion to be cut, and corresponds to the portion where the cutting start region is formed. Since only the part can be cleaved, the cleaving can be controlled well. In recent years, since the thickness of workpieces such as silicon wafers tends to be thin, such a cleaving method with good controllability is very effective.

- the horizontal axis represents the peak power density. Since the laser beam is a panorless laser beam, the electric field strength is represented by the peak power density.
- the vertical axis shows the size of cracks (crack spots) formed inside the workpiece by one pulse of laser light. Crack spots gather to form a crack area. The size of the crack spot is the size of the maximum length of the crack spot shape.
- the data indicated by black circles in the graph is for the case where the condenser lens (C) has a magnification of 100 and a numerical aperture (NA) of 0.80.
- the data indicated by white circles in the graph is for the case where the magnification of the condenser lens (C) is 50 times and the numerical aperture (NA) is 0 ⁇ 55. It can be seen that crack spots are generated inside the workpiece from the peak power density of about 10 1 1 (WZ cm 2 ), and the crack spots increase as the peak power density increases.
- the laser beam L is irradiated to the workpiece 1 by aligning the condensing point P inside the workpiece 1 under the condition that multiphoton absorption occurs, and the inside of the workpiece 1 is cracked along the planned cutting line.

Silicon wafers are cracked in the cross-sectional direction starting from the cutting start region formed in the melt processing region, and as a result, the crack reaches the front and back surfaces of the silicon wafer. Disconnected.
- the cracks that reach the front and back surfaces of the silicon wafer may grow spontaneously, or they may grow when force is applied to the silicon wafer.
- the crack grows from the state in which the melt processing area forming the cutting start area is melted, and the cutting start point.
- cracks grow when the solidified region is melted from the melted region that forms the region.
- the melt processing region is formed only inside the silicon wafer, and the melt processing region is formed only inside as shown in FIG. If a cutting start area is formed in the melt processing area inside the workpiece, it is easy to control the cleaving because it is difficult to cause unnecessary cracks off the cutting start area line during cleaving.
- the focusing point is set inside the object to be processed (for example, glass), and the laser beam is emitted under the condition that the electric field strength at the focusing point is 1 X 10 8 (W / cm 2 ) or more and the pulse width is 1 ns or less. Irradiate.

- the cutting starting region is formed as follows in consideration of the crystal structure of the wafer-like workpiece and its cleavage property, etc., with the cutting starting region as the starting point, the force is further reduced. In addition, it is possible to cut the workpiece with high accuracy.
