Abstract:
A method of making a capacitor structure comprising the steps of:forming a dielectric layer over a first electrode layer substrate, said forming a dielectric layer comprising the steps of: introducing a vapor formed from a tantalum containing liquid precursor comprising TBTDET or EITDET-c into a chamber in which the substrate resides; introducing a first reactant into the chamber; and reacting the vapor formed from the precursor comprising TBTDET or EITDET-c and the reactant to form and deposit the dielectric layer over the first electrode layer; and forming a second electrode layer over the dielectric layer, said forming a second electrode layer comprising the steps of: introducing the vapor formed from a tantalum containing liquid precursor comprising TBTDET or EITDET-c into a chamber in which the substrate, including the dielectric layer resides; introducing a second reactant into the chamber; and reacting the vapor formed from the precursor comprising TBTDET or EITDET-c and the second reactant to form and deposit the second electrode layer over the dielectric layer.
