First, it is a highly flammable solid and a dust explosion hazard. Second, zirconium is routinely found with some level of hafnium, since separation of the two elements is very difficult [3].The ...
Read MoreHafnium oxide (HfO/sub 2/) was investigated as an alternative possible gate dielectric. A MOS capacitor using HfO/sub 2/ as dielectric was fabricated and studied. The HfO/sub 2/ film was formed by direct sputtering of Hf in O/sub 2/ and Ar ambient on to a Si substrate and post-sputtering rapid thermal annealing (RTA). XPS results showed that the interface layer formed between the HfO/sub 2 ...
