- JP 2009-272323 A Japanese Patent No. 5582916
- the grindstone is a so-called reservoir due to the sliding resistance generated in the guide when the guide approaches the wafer. Since it moves by feeding, it was difficult to cut the wafer with a fine grinding amount. If the cutting depth of the grindstone (abrasive grain) is larger than the critical cutting depth (Dc value) of the wafer, as shown in FIG. 7, brittle mode grinding in which the wafer is chipped or cracked during grinding of the wafer. There was a risk of becoming.
- the point that supports the grindstone is separated from the working point to be processed and is often a cantilever type.

- the grindstone and the spindle are lowered along the direction of gravity and force is applied to the wafer. Even if the sharpness of the tip of the grindstone changes, since the wafer is pressed with a constant pressure, a cut corresponding to the sharpness is given to the wafer. This makes it possible to give a cut to the wafer while feeding the grindstone at a predetermined pressure according to the sharpness of the grindstone, compared to the conventional method of feeding the grindstone at a constant speed, giving a stable cut and cracking. Can be suppressed. In addition, since the grindstone is automatically sent according to the speed at which the actual wafer is removed by the processing, it is possible to continue the constant incision processing stably during the processing.

- a constant pressure cylinder 26 is provided on each side of the horizontal direction H across the nut 25a of the spindle feed mechanism 25, and is interposed between the column 22 and the nut 25a.
- the constant pressure cylinder 26 is an air cylinder that employs a known configuration including a cylinder, a piston, a piston rod, a compressor, and the like (not shown).
- the driving pressure of the constant pressure cylinder 26 is set to a value corresponding to the frictional force acting on the grindstone 21 when the grindstone 21 is cut by the critical cutting depth (Dc value) of the wafer W.
- the Dc value varies depending on the material of the wafer W, and is 0.09 ⁇ m for a silicon wafer and 0.15 ⁇ m for a silicon carbide wafer, for example.
- the constant pressure cylinder 26 has a spindle 23 and a spindle feed mechanism 25 suspended in a groove 22b. Specifically, the lower end of the piston rod of the constant pressure cylinder 26 is connected to the nut 25a, and when the frictional force acting on the grindstone 21 during grinding is transmitted to the piston rod, the compression filled in the cylinder of the constant pressure cylinder 26 is performed.

- the feed amount can be controlled with high accuracy.
- the spindle feed mechanism 25 is restricted from being inclined in the horizontal direction H when the spindle feed mechanism 25 is raised. Therefore, as shown in FIG. 5, the wafer W can be subjected to ductile mode grinding in a so-called floating state in which the abrasive grains of the grindstone 21 do not excessively contact the wafer W during grinding.
- the SiC substrate is subjected to ductile mode grinding using the grinder 1
- a # 8000 grindstone 21 is prepared, the rotation speed of the spindle 23 is 2000 rpm, the rotation speed of the chuck 31 is 300 rpm, It is conceivable to set the grinding load to 20 kg and the feed speed of the spindle feed mechanism 25 to 0.4 ⁇ m / s.
- the “load during grinding” corresponds to the driving pressure (500 kPa) of the constant pressure cylinder 26 set when the grindstone 21 is separated from the wafer W by 1 ⁇ m.
- the constant pressure cylinder 26 is replaced with the spindle feed mechanism 25.
- the wafer W is subjected to ductile mode grinding in a state where the spindle 23 is in a floating state by temporarily increasing the pressure and suppressing the pressure concentration at the processing point P, so that the wafer W can be stably ground without damaging it. Can do.
- the spindle feed mechanism 25 is restricted from moving in the horizontal direction H, so that the ductile mode grinding with the spindle 23 floating is further stabilized. Can be done.
- the feeding direction D2 is parallel to the vertical direction V and arranged on a straight line passing through the processing point P of the grindstone 21, the grindstone is used when grinding the wafer W with the spindle 23 floating. Since the spindle feeding mechanism 25 sends out the spindle 23 so as to suppress the reaction force when the 23 comes into contact with the wafer W, ductile mode grinding with the spindle 23 floating can be performed more stably. Further, since the spindle 23 performs grinding while pressing the wafer along the vertical direction V only by its own weight, it has a small sliding resistance and is minute compared to a conventional grinding machine that feeds and grinds a grindstone in the horizontal direction. It is possible to grind with the depth of cut.
- the linear guide 24 arranged around the spindle 23 regulates the attitude of the spindle 23, so that it floats. In this state, ductile mode grinding can be performed stably.
- the specific configuration of the constant pressure feed mechanism is not limited to that described above, and any configuration may be used as long as the spindle can be raised so as to release excessive frictional force acting on the grindstone. .
- the specific configuration of the linear guide is not limited as long as it can regulate the vertical movement of the spindle in the vertical direction.
- the center of gravity of the spindle in a plan view is arranged in the polygon formed by the linear guide.
- the spindle is supported by two linear guides, and the center of gravity of the spindle is arranged on a straight line formed by the two linear guides in plan view. It doesn't matter.
