ABSTRACT:
An ion-beam sputtering apparatus using an insulator target and a method for operating the same which is characterized by interposing a conductor film forming process during the ion beam processings using the insulator target. This conductor film formation prevents undesired charge build up on the inside of the apparatus and prevents undesired occurrence of abnormal discharge in the ion beam processing using an insulator as a target.
