This paper deals with the development of a novel polishing technique for the glass substrate for electric devices by applying AC electric field. In order to grasp the movements of the slurry under AC electric field, we have observed slurry behaviors with an observation device we developed, and found that the slurry was smoothly led to the polishing area by AC electric field. Furthermore, effectiveness of the slurry distribution on the polishing area increased by 12%. Polishing rate also increased 22% compared to the conventional polishing when AC electric field was applied. This will contribute to the reduction of the consumption of the cerium oxide abrasives.
