What is HAFNIUM TERT-BUTOXIDE?

The Uses of HAFNIUM TERT-BUTOXIDE

Hafnium tert-butoxide [Hf(OtBu)4] is a mononuclear; volatile; and highly promising precursor for the deposition of HfO2 and other hafnium doped thin films by vapor deposition techniques. The deposited films show high dielectric constant suitable for semiconductor devices.
