- the peaks assigned to Ru 3 d orbitals were observed at 280 e V and 284 e V, and the peaks derived from other elements were not observed at all, which is metallic ruthenium. I found that.
- the resistivity of this metal ruthenium film was measured by the four-terminal method, and it was 13 zQcm.
- the film density of this film was 12.6 gZcm 3 .
- a quartz port container and a quartz substrate in which 0.1 g of the 2, 3 -dimethyl-1, 3-butajenyl ruthenium tetrahydride obtained in the above Synthesis Example 11 is placed in a quartz tubular reaction vessel are provided. I set it. Nitrogen gas was flowed for 30 minutes at a flow rate of 25 OmL / min from the quartz port type vessel side into the reaction vessel at room temperature. After that, a hydrogen / nitrogen mixed gas (hydrogen content 3 V 01%) was flowed into the reaction vessel at a flow rate of 50 mL / min, the pressure in the system was further reduced to 650 Pa, and the reaction vessel was heated to 180 ° C. Mist is generated from the port type container and at the same time the deposit on the quartz substrate is formed to a thickness of 47 OA in 30 minutes It was made.
- Nitrogen gas was flowed for 30 minutes at a flow rate of 25 OmL / min from the quartz port type vessel side into the reaction vessel at room temperature. After that, a hydrogen
- Dry nitrogen gas is introduced to return to normal pressure, and then the reaction vessel is subjected to 350 ° while flowing a hydrogen / nitrogen mixed gas (hydrogen content 3 V 01%) at a flow rate of 50 OmL / min at 101.3 kPa.
- a hydrogen / nitrogen mixed gas hydrogen content 3 V 01%
- the film thickness of this film was 41 OA.
- the peaks attributable to Ru 3 d orbitals were observed at 280 eV and 284 eV, and the peaks derived from other elements were not observed at all, and thus it was metallic ruthenium. understood.
- the specific resistance of this ruthenium metal film was measured by the four-terminal method to be 15. 8 / Q cm.
- the film density of this film was 12.6 g / cm 3 .
