Vacuum coating machines and dynamic magnetic field magnetron sputtering source

Motorized vacuum coating magnetic field magnetron sputtering vacuum coating sources, including the target substrate, solder or crimp ring is fixed in front of the target substrate sheet target, shielding ring, magnet board, within the magnet mounted on a magnet board and outside the magnet, the improvements made are: the diameter of the magnet is greater than the radi...us of the target substrate, and smaller than the diameter of the target, the target substrate magnet axis offset from the axis of the substrate, the substrate magnet fixed gear on a positive side, the coating machine ring gear meshing with the spur gear installed on the rack, the rear side of the installation located spur gear motor, motor power output shaft fixed to the frame turn handle, mounted on the gear shaft turn handle. Motor power output shaft and the ring gear coaxial with the target board settings.

The positive effect of this invention is: get a revolution and rotation of the annular magnetic field to scan to each target position, so that the target in a larger area to be etched shot off evenly. High target utilization, coating uniformity.
A moving magnetic field magnetron sputtering vacuum deposition coater, comprising a vacuum deposition chamber in front of the target substrate, welded or fixed to the sheet-shaped pressure ring positive target target substrate, covering the peripheral side surface of the target substrate and the target substrate positive target shielding material outside of the ring portion, an annular outer magnet disposed in combination target substrate on the back of the magnet substrate, the magnet is mounted on the center position of the magnet toward the substrate and the target substrate side circumferential position or arranged in rings outside the magnet,
Its features are: the diameter is larger than the radius of the target substrate magnet, and smaller than the diameter of the target, the target substrate magnet axis offset from the axis of the substrate, the substrate magnet fixed gear on a positive side, the installation and the coating machine frame ring spur gear, is mounted on the rear side of the spur gear rack located motor, the motor power output shaft fixed turn handle, mounted on the gear shaft turn handle.
