However, in the processing method of 1) above, cracks or cracks are likely to occur in the ceramics due to the force applied to the ceramics to be processed at the time of processing and the residual stress, which causes a decrease in yield. There are also problems in terms of cost, such as low machining efficiency and high tool consumption costs. In the machining method of 2) above, removal of abrasives during machining and cleaning after machining Since it requires time and labor, complicated work is required, and noise during processing is also a problem.

In the processing method of 3) above, for example, alumina nitride (aluminum nitride), which is a kind of fine ceramics, is excellent in electrical insulation.
It is also widely used as a material for electronic substrates and the like because it has the property of high thermal conductivity. However, when an electronic substrate made of such an alumina nitride is melt-cut with a laser to be processed, There is a problem that aluminum atoms vaporized by thermal energy are vapor-deposited on the electronic substrate and the insulating property is significantly lowered. Further, when a compound containing a harmful element such as gallium arsenide is used as a material for ceramics, there is a problem that arsenic vapor, which may harm the human body, is generated, which is not preferable. In addition, it has been pointed out that the conventional laser processing machine lacks in its performance, and there is a problem that the laser processing machine lacks mass productivity in terms of the price and running cost of the processing machine itself.
