Abstract: PURPOSE: An improved collimator and a method for making thereof in a sputtering apparatus are provided to prevent deformation of the collimator caused by a difference in a thermal stress between a collimating region and a non-collimating region. CONSTITUTION: In a sputtering apparatus including a target(10) and a wafer(30), a collimator(20) is disposed between the target(10) and the wafer(30). In particular, the collimator(20) capable of collimating metallic particles sputtered from the target(10) to the wafer(30) has a reduced size in due consideration of actual collimating operation. Accordingly, there never occur any thermal stress in the collimator(20), and thereby undesirable deformation of the collimator(20) is effectively prevented. Furthermore, a ring-shaped shield coring(40) having plural hole(42) is equipped under peripheries of the collimator(20). In a fabrication of the collimator(20), an original circular plate is provided, and then plural holes are formed in the original circular plate.
