| 1 | Why can you always have vexed thing hafnium? | |
| 2 | Addition of Hf to a superalloy is one of the effective approaches to improve its mid-temperature properties. | |
| 3 | Specifically, the present invention provides a metal stack comprising a hafnium-based dielectric; | |
| 4 | Mainly because the quantity of hafnium, utilized in one chip, is negligibly small. | |
| 5 | Tungsten and hafnium in tantalum alloys was determined by ICP-AES. |
