  • Patent number: 10066290
    Abstract: A sintered compact magnesium oxide target for sputtering has a purity of 99.99 wt % or higher excluding C, a density of 3.57 g/cm3 or higher, and a whiteness of 60% or less. To uniformly deposit a magnesium oxide film, a magnesium oxide target having a higher purity and a higher density is demanded. An object is to provide a target capable of realizing the above and a method for producing such a target. While a magnesium oxide sintered compact sputtering target is produced by hot-pressing a raw material powder, there is a problem in that color shading occurs in roughly ?60 (within a circle having a diameter of 60 mm) at the center part of the target. Conventionally, no particularly attention was given to this problem. However, in recent years, it has become necessary to investigate and resolve this problem in order to improve the deposition quality.
