Abstract

Official abstract text for this publication.

Disclosed is a ruthenium compound useful as a precursor in chemical vapor growth, particularly ALD. The compound has good reactivity with a reactive gas, a high vapor pressure, and a low melting point. The compound is represented by general formula (I), wherein R1, R2, and R3 each independently represent a straight or branched chain alkyl group having 1 to 5 carbon atoms, provided that the total number of the carbon atoms of R1 and R2 is 3 to 10. In formula (I), R1 and R2 are each preferably ethyl or isopropyl.

First claim

Opening claim text (preview).

The invention claimed is: 1. A ruthenium compound represented by general formula (I): wherein R 1 , R 2 , and R 3 each independently represent a straight or branched chain alkyl group having 1 to 5 carbon atoms, provided that the total number of the carbon atoms of R 1 and R 2 is 3 to 10. 2. The ruthenium compound according to claim 1 , wherein R 1 and R 2 are each an ethyl group. 3. The ruthenium compound according to claim 1 , wherein R 1 and R 2 are each an isopropyl group. 4. A material for thin film formation comprising the ruthenium compound according to claim 1 . 5. A process for forming a thin film comprising vaporizing the material for thin film formation according to claim 4 and introducing the ruthenium compound-containing vapor into a deposition chamber having a substrate placed therein to cause the ruthenium compound to decompose and/or chemically react to form a ruthenium-containing thin film on the substrate. 6. A material for thin film formation comprising the ruthenium compound according to claim 2 . 7. A material for thin film formation comprising the ruthenium compound according to claim 3 .
