Abstract

A magnetron sputtering electrode 2 is attached to a vacuum chamber 1 to make it retain a Ti target 4 via a back plate 3. A substrate 9 is loaded on a substrate holder 8 provided at a lower portion of the vacuum chamber 1. A collimation plate 6 is provided between the substrate 9 and the Ti target 4 to pass through only the sputtered particles advancing in the vertical direction, and, at its outside, shield plates 5, 7 are provided. The shield plate 5 at the target side is shaped in a wave form and thus its surface area is increased so that nitrogen can be adsorbed as much as possible.
