Hafnium silicide target for forming gate oxide film, and method for preparation thereof |
| 摘要 |
A hafnium silicide target is provided. The target is used for forming a gate oxide film composed of HfSi1.02-2.00. The target material is superior in workability and embrittlement resistance and is suitable for forming a HfSiO film and HfSiON film that may be used as a high dielectric gate insulation film in substitute for a SiO2 film. A method of manufacturing the above referenced hafnium silicide target is also provided.
