Abstract
Multilayered hardmask structures are provided which can prevent degradation of the performance of a magnetic tunnel junction (MTJ) structure. The multilayered hardmask structures include at least a halogen barrier hardmask layer and an upper hardmask layer. The halogen barrier hardmask layer can prevent halogen ions that are used to pattern the upper hardmask layer from diffusing into the MTJ structure.
