摘要
Thin films of tantalum oxide and tantalum nitride for microelectronics applications can be deposited by MOCVD using direct injection of same liquid precursors of the type R-N = Ta(NEt2)(3). High-k mixed-metal oxides, such as Zr-Sn-Ti-O, metal doped TaOx and zirconium silicate, can also be deposited at relatively low temperatures from liquid mixtures as single-source precursors without solvent, This solventless CVD system is considered a more cost effective and environmentally benign process than conventional liquid injection of metal-organic precursors dissolved In organic solvents, In addition, recent advances in copper CVD precursors are reviewed.
