However, according to this means, there is a concern that sufficient effects cannot be exhibited unless hard particles are present on the chip surface. Moreover, with this means, it is necessary to mix hard particles at the time of chip preparation, the chip preparation process is extremely difficult, and there is also a risk of abrasion of the device itself due to hard particles, and the chip manufacturing apparatus. There was also a management problem.
