Abstract
A deposition apparatus, which forms a film on a substrate, includes a rotation unit configured to rotate a target about a rotating axis; a striker configured to generate an arc discharge; a driving unit configured to drive the striker so as to make a close state which the striker closes to a side surface around the rotating axis of the target to generate the arc discharge; and a control unit configured to control rotation of the target by the rotation unit so as to change a facing position on the side surface of the target facing the striker in the close state.
Claims2
A deposition apparatus which forms a film on a substrate, comprising:
- a moving unit configured to move a target along a moving axis;
- a striker configured to generate an arc discharge;
- a driving unit configured to perform rotation-drive of the striker so as to make a state in which the striker and a side surface around the moving axis of the target are electrically connected to each other to generate the arc discharge;
- and
- a control unit that is configured to control movement of the target by the moving unit so as to change a facing position on the side surface of the target facing the striker in the state,
- wherein an axis of the rotation-drive of the striker is parallel to the moving axis;
- wherein the control unit is further configured to change the facing position each time a size of an arc spot generated in the target by the arc discharge becomes larger than a predetermined size.
