- S I_ ⁇ 2 film is used as the gate insulating film were those best viewed from the interface characteristics.
- the transistor is being miniaturized, but as described above, since the thickness of the SiO 2 film as the gate insulating film is limited, the miniaturization of the transistor does not make sense and the performance is not improved. The problem arose.
- This high-dielectric gate insulating film is a relatively thick film, is capable of obtaining the same capacitance as that of the Si ⁇ 2 film, and has a feature that a tunnel leakage current can be suppressed. Moreover, since it can be assumed that the addition of H f to S i 0 2 S i On, the interface characteristics are also expected to be close to S i 0 2.
- the present invention provides an HfSi ⁇ film and a HfSiON film which can be used as a high-dielectric gate insulating film having characteristics replacing the Si 2 film.
- An object of the present invention is to provide a hafnium silicide evening gate which is suitable for forming a film and which is excellent in workability, embrittlement resistance and the like, and a method for producing the same.
- the present invention is a.

- the relative density is less than 95%, the brittleness is reduced due to insufficient density, and the workability is deteriorated.
- particles increase due to fracture and scattering of brittle crystals. Therefore, it is desirable to be within the above range.
- the oxygen content in the gate oxide film forming hafnium silicide is preferably 500 to 10,000 ppm. If the oxygen is less than 500 ppm, there is a danger of ignition during the manufacture of the evening getter, and if it exceeds 10,000 ppm, the oxygen in the evening get precipitated as an oxide and causes abnormal discharge during the sparkle. This is because the number of particles increases and the product yield decreases.
- the content of zirconium in the target be kept at 2.5 wt% or less. If the zirconium content exceeds 2.5 wt%, process conditions such as voltage, current, and substrate temperature during reactive sputtering for forming an oxide film greatly fluctuate, which is not preferable.

Under the hot-pressing condition at 1700 ° ( ⁇ 1830 ° C), the relative density was similarly improved. As described above, the ratio of Hf: Si was reduced to 1: 0.37 or less. Although the reason was not necessarily clarified by reducing the density, it was confirmed that the density of the sintered body could be stably improved as shown in the examples.
