چکیده

The tungsten piperidylhydrazido complex Cl4(CH3CN)W(N-pip) (1) was used as a single-source precursor for growth of tungsten carbonitride (WNxCy) by metal-organic chemical vapor deposition (CVD) in H2 carrier. Multiple spectroscopic techniques were used for preliminary evaluation of the suitability of 1 as a precursor and to suggest possible fragmentation pathways. The effect of growth temperature on film microstructure, lattice parameter, average grain size, chemical composition, chemical bonding states, growth rate, film resistivity, and sheet resistance was studied.

A mixture of the tungsten allylimido complexes Cl(4)(RCN)W(NC(3)H(5)) (3a, R = CH(3) and 3b, R = Ph) was tested as a single-source precursor for growth of tungsten nitride (WN(x)) or carbonitride (WN(x)C(y)) thin films. Films deposited from 3a,b below 550 degrees C contained amorphous beta-WN(x)C(y), while those deposited at higher temperatures were polycrystalline. Film growth rates from 3a,b ...

Diorganohydrazido(2-) complexes of tungsten (L)Cl4W(NNR2) [R2=Me2, Ph2, -(CH2)5-; L=CH3CN, pyridine] were synthesized by reacting the corresponding 1,1-diorganohydrazine with WCl6, followed by reaction with acetonitrile or pyridine. Crystallographic structure determination of (CH3CN)Cl4W(NNMe2) and (CH3CN)Cl4W(NNPh2) allows a comparison of the structural features of the diorganohydrazido(2-) fu...
