Patent ID: 8882976

Claim:
A magnetron unit moving apparatus to prevent magnetization of a planar target having a length and a width, comprising: a magnetron unit installed in a vacuum chamber comprising a first region and a second region and disposed adjacent to the target, the magnetron unit consisting of a magnet to generate a magnetic field and a fixing plate supporting the magnet and configured to rotate around an axis parallel with the length of the target; an isolation plate disposed in the vacuum chamber, surrounding the magnetron unit, to isolate the first region from the second region, the isolation plate being configured to absorb the magnetic field; and a movement unit comprising a rotation unit configured to rotate the fixing plate between a first position where sputtering occurs, and a second position where sputtering is prevented, such that the magnet is disposed between the fixing plate and the target, when the fixing plate is in the first position, and the fixing plate is disposed between the magnet and the target and a strength of a magnetic field generated over the target is within a reference strength range that prevents magnetization of the target, when the fixing plate is in the second position.
