Abstract

Exemplary substrate locking system, device, apparatus and method for chemical and/or electrolytic surface treatment of a substrate in a process fluid can be provided. For example, it is possible to provide a first element, a second element and a locking unit. The first element and the second element can be configured to hold the substrate between each other. The locking unit can be configured to lock the first element and the second element with each other. The locking unit can comprise a magnet control device and a magnet. The magnet can be arranged at or near the first element and/or the second element. The magnet control device can be configured to control a magnetic force between the first element and the second element.

Claims (37)

1. A substrate locking system for at least one of a chemical surface treatment or a electrolytic surface treatment of a substrate in a process fluid, comprising:

a first element and a second element, wherein the first element and the second element are configured to hold or maintain the substrate between each other; and

a locking arrangement configured to lock the first element and the second element with each other,

wherein the locking arrangement comprises a magnet control device and at least one magnet,

wherein the at least one magnet is arranged at at least one of the first element or the second element,

wherein the magnet control device is configured to control a magnetic force between the first element and the second element, and wherein the first element is a substrate holder, and the second element is a first contact loop; and

a second contact loop configured to hold a further substrate between a reverse side of the substrate holder and the second contact loop, wherein the locking arrangement is configured to independently lock each of the first and second contact loops and the substrate holder with one another.

2. The substrate locking system according to claim 1 , wherein the first element is a first contact ring, and the second element is a second contact ring, and wherein the first and second contact rings are configured to hold at least one substrate between each other.

3. The substrate locking system according to claim 1 , wherein the at least one of the magnets is arranged at or near the first element.

4. The substrate locking system according to claim 1 , wherein the at least one of the magnets is a permanent magnet configured to lock the first element to the second element.

5. The substrate locking system according to claim 4 , wherein the magnet control device is configured to reduce or eliminate the magnetic force of the permanent magnet to facilitate a release of the second element from the first element.

6. The substrate locking system according to claim 4 , wherein the magnet control device is configured to control the magnetic force between the first element and the second element by applying a voltage.

7. The substrate locking system according to claim 1 , wherein the second element at least partially comprises a magnetic material.

8. The substrate locking system according to claim 1 , wherein the second element is at least partially electrically conductive.

9. The substrate locking system according to claim 1 , wherein the second element comprises a plurality of contact fingers made of magnetic material.

10. The substrate locking system according to claim 9 , wherein the first element comprises an electrical conductor rod extending along the first element.

11. The substrate locking system according to claim 1 , further comprising a sealing arrangement provided between the first element and the second element, wherein the sealing arrangement is configured to ensure a liquid-tight connection between the substrate, the first element and the second element.

12. The substrate locking system according to claim 11 , wherein the first element is a substrate holder, and the second element is a contact loop, wherein the substrate holder and the contact loop are configured to hold at least one substrate between each other, wherein the sealing arrangement comprises (i) an inner sealing configured to ensure a liquid-tight connection between the substrate and the contact loop, and (ii) an outer sealing configured to ensure a liquid-tight connection between the substrate holder and the contact loop.

13. The substrate locking system according to claim 1 , wherein the locking arrangement comprises a plurality of magnets distributed at or near the first element along the substrate to be held.

14. A substrate locking system for at least one of a chemical surface treatment or a electrolytic surface treatment of a substrate in a process fluid, comprising:

a first element and a second element, wherein the first element and the second element are configured to hold or maintain the substrate between each other; and

a locking arrangement configured to lock the first element and the second element with each other,

wherein the locking arrangement comprises a magnet control device,

wherein the second element comprises arrays of contact fingers arranged in contact with a plurality of magnets distributed at or near the first element,

wherein at least one of the magnets is arranged at or near at least one of the first element or the second element,

wherein the magnet control device is configured to control a magnetic force between the first element and the second element, and wherein the first element is a substrate holder and the second element is a first contact loop; and

a second contact loop configured to hold an additional substrate between a reverse side of the substrate holder and the second contact loop, wherein the locking arrangement is configured to independently lock each of the first and second contact loops and the substrate holder with one another.

15. A substrate locking system for at least one of a chemical surface treatment or a electrolytic surface treatment of a substrate in a process fluid, comprising:

a first element and a second element, wherein the first element and the second element are configured to hold or maintain the substrate between each other; and

a locking arrangement configured to lock the first element and the second element with each other,

wherein the locking arrangement comprises a magnet control device and a magnet,

wherein the magnets is arranged at or near at least one of the first element or the second element,

wherein the magnet control device is configured to control a magnetic force between the first element and the second element,

wherein the first element comprises an electrical conductor rod extending along the first element,

wherein the second element comprises a plurality of contact fingers made of a magnetic material,

wherein one end of the contact fingers contacts the magnet, and wherein the magnet contacts the electrical conductor rod, and wherein the first element is a substrate holder and the second element is a first contact loop; and

a second contact loop configured to hold a further substrate between a reverse side of the substrate holder and the second contact loop, wherein the locking unit is configured to independently lock each of the first and second contact loops and the substrate holder with one another.
