Application of interface engineering methods to CVD growth of thin tungsten films on silicon substrate
The interface modeling,thermodynamic considerations and study of the self-organization phenomenon of reaction zone are ap plied to optimization of chemical vapour deposition (CVD) of thin tungsten films on silicon substrate-perspective materials for multilay ered contact metallization of integrated circuits.It was shown that the formation of selflimited nanoscale W,Si,silicide sublayer and low energy coherent interfaces in the W-film/W5 si3-sublayer/Si (001)-substrate heterosysystem in non equilibrium CVD-method are results of the system internal self-organization.Based on interface design methods a procedure to fabricate by CVD stable tungsten thin films of high-conductivity (8×10-6 Ohm·cm)and high adhesion was developed.
