摘要： A tantalum nitride film rich in tantalum atoms is formed by simultaneously introducing a raw gas consisting of a coordination compound of elemental tantalum (Ta) having a coordinated ligand of formula: N═(R, R′) (wherein, R and R′ each represents an alkyl group having 1 to 6 carbon atoms) and NH3 gas into a film-forming chamber; reacting the raw gas with the NH3 gas; forming a reduced compound having Ta—NH3 on a substrate; and introducing a hydrogen atom-containing gas into the chamber to form a tantalum nitride film rich in tantalum atoms. The resulting tantalum nitride film has a low resistance, low contents of C and N atoms, and a high compositional ratio: Ta/N, show sufficiently high adherence to Cu film and can thus be useful as a barrier film. Moreover, tantalum particles are implanted in the resulting film according to the sputtering technique to further enrich the film with tantalum.

摘要： Rapid thermal nitridation is carried out to form a nitride film on a lower electrode which is made of silicon, and a tantalum oxide dielectric film is further formed thereon. Then, wet oxidization is carried out to oxidize the lower electrode through the dielectric film and the nitride film, thus an oxide film is formed between the lower electrode and the nitride film. Further, silicon which is not bonded to nitrogen in the nitride film is oxidized, thus an oxide film whose effective thickness is equal to or greater than 2 nm. The oxidization also recrystallizes the dielectric film. Finally, an upper electrode is formed, and the capacitor is completed.

摘要： A tantalum nitride film-forming method comprises the steps of introducing, into a vacuum chamber, a raw gas consisting of a coordination compound constituted by elemental Ta having a coordinated ligand represented by the general formula: N═(R,R′) (in the formula, R and R′ may be the same or different and each represents an alkyl group having 1 to 6 carbon atoms) to thus adsorb the gas on a substrate; then introducing an NH3 gas and then activated H radicals derived from a reactant gas into a vacuum chamber to thus remove the R(R′) groups bonded to the nitrogen atom present in the reaction product through cleavage, and to thus form a tantalum nitride film rich in tantalum atoms. The resulting tantalum nitride film has a low resistance, low contents of C and N atoms, and a high compositional ratio: Ta/N, can ensure sufficiently high adherence to the distributing wire-forming film and can thus be useful as a barrier film. Moreover, tantalum particles are implanted in the resulting film according to the sputtering technique to thus further enrich the film with tantalum.
