Wherein, the etching arc target and the coating arc target 125 adopt the same structure to connect the fixed magnetic field assembly 127 and the movable magnetic field assembly 128. Since, hereinafter, the connection structure and the operation principle of the fixed magnetic field assembly 127 and the movable magnetic field assembly 128 of the arc target 125 are described by taking the arc target 125 as an example, the connection structure and the operation principle of the fixed magnetic field assembly 127 and the movable magnetic field assembly 128 of the arc target are only needed to refer to the arc target 125, which is not described herein again.

Specifically, the coating arc targets 125 are all mounted on the vacuum chamber 10 through an insulating connection assembly, the fixed magnetic field assembly 127 is disposed outside the vacuum chamber 10 corresponding to the coating arc targets 125, and the movable magnetic field assembly 128 is movably connected with the fixed magnetic field assembly 127 through an adjustment assembly, so that by operating the adjustment assembly, the relative position relationship and the superposition effect of the magnetic field generated by the movable magnetic field assembly 128 and the magnetic field generated by the fixed magnetic field assembly 127 can be changed, so as to generate a variable magnetic field acting on the coating arc targets 125. That is, the variable magnetic field is a superposition of the magnetic field generated by the first fixed magnetic field assembly 127 and the magnetic field generated by the first movable magnetic field assembly.

Through setting up fixed magnetic field subassembly 127, can ensure that variable magnetic field satisfies basic magnetic control requirement, on this basis, through setting up the movable magnetic field subassembly 128 with fixed magnetic field subassembly 127 swing joint for variable magnetic field can be adjusted as required, specifically speaking, only need adjust the position of movable magnetic field subassembly 128 for fixed magnetic field subassembly 127, can realize the regulation to the control magnetic field. Therefore, the variable magnetic field can be adjusted to a desired state, so that the collision ionization probability of electrons and argon can be increased, the deposition rate is improved, the collision probability of electrons and metal atoms is increased, and the metal ionization rate is greatly improved.

Wherein, insulating coupling assembling and lateral part bulk phase are connected, and coating arc target 125 connects in the part that is located the coating film cavity body of insulating coupling assembling to not only can install coating arc target 125 in vacuum chamber 10 through this insulating coupling assembling, can prevent coating arc target 125 and vacuum chamber 10 direct conduction through insulating coupling assembling moreover, ensure that coating arc target 125 can realize discharging and also realize the target evaporation.

The movable magnetic field assembly 128 includes a frame body and a movable magnetic member disposed on the frame body, the frame body is provided with a mounting hole, the frame body is movably sleeved outside the mounting seat 1270 through the mounting hole, so that the movable magnetic member can move synchronously with the frame body, and thus the movable magnetic member moves relative to the mounting seat 1270, that is, the movable magnetic member and the magnetic field generated by the movable magnetic member can be movably mounted relative to the arc target.

Further, the structures of the movable magnetic member of the etching arc source and the movable magnetic member of the plating arc source 12 can be arranged differently, the movable magnetic member of the etching arc source comprises a first movable magnetic member, the movable magnetic member of the plating arc source 12 comprises a second movable magnetic member and a third movable magnetic member, and at least one of the second movable magnetic member and the third movable magnetic member is an electromagnetic coil.

Because the magnetic field of the movable magnetic field assembly 128 of the etching arc source is only generated by the first movable magnetic member, and the magnetic field generated by the movable magnetic field assembly 128 of the coating arc source 12 is formed by overlapping the magnetic field of the second movable magnetic member and the magnetic field of the third movable magnetic member, the arrangement rule of the magnetic lines of force of the magnetic field generated by the coating arc source 12 can be more three-dimensional, so that the coating magnetic control is more accurate, the coating quality is improved, the structure of the etching arc source is simpler, and the cost control is facilitated on the premise of meeting the etching magnetic control requirement.

When the adjustment sleeve 120 is rotated with respect to the outer plate 130, the fixing sleeve 121 rotates with respect to the adjustment sleeve 120, and the fixing sleeve 121 moves in the height direction of the mount 1270 while rotating.

Such as forward rotation of the adjustment sleeve 120, the fixed sleeve 121 is raised relative to the mounting block 1270 and causes the movable field assembly 128 to raise relative to the fixed field assembly 127 to effect a forward superposition adjustment of the control field, whereas, such as reverse rotation of the adjustment sleeve 120, the fixed sleeve 121 is lowered relative to the mounting block 1270 and causes the movable field assembly 128 to lower relative to the fixed field assembly 127 to effect a reverse superposition adjustment of the variable field. So that the variable magnetic field can be conveniently adjusted as required by the adjusting assembly.

In this embodiment, as an implementation of the structure of the insulating connection assembly, the insulating connection assembly includes an insulating spacer 123, a target fixing flange 122, and an insulating ring 124.
