Patent ID: 8808514

Claim:
A magnetron sputtering apparatus, comprising: a deposition chamber in which a substrate mount is provided; a processing chamber in communication with the deposition chamber, wherein a target area composed of targets is located at a place where the processing chamber is connected with the deposition chamber; a transfer chamber provided adjacent to the processing chamber, wherein a first gas-tight gate is provided on a wall of the transfer chamber, the first gas-tight gate is capable of being opened or closed so as to control the vacuum degree in the transfer chamber and to accommodate targets for replacement; a transfer device which is provided in the processing chamber or in the transfer chamber, transfers the targets for replacement between the transfer chamber and the processing chamber via a second gas-tight gate provided on the adjacent walls of the transfer chamber and the processing chamber for replacement when the transfer chamber is in a set vacuum degree state; wherein the target area is formed by the combination of a plurality of planar targets or a plurality of rotational targets, a moving base provided at a connection point between the processing chamber and the deposition chamber, wherein the plurality of targets are deployed on a driving rack of the moving base, and the driving rack transmits the targets to be replaced out of the target area for replacement; and a gap adjustment apparatus provided in the path of the driving rack transmitting the targets to be replaced, for adjustment of the gap between adjacent targets.
