PDMAT
Synonym: Pentakis(dimethylamino)tantalum(V), TADMA, Ta(NMe2)5, Tantalum dimethylamide, Ta(N(CH3)2)5
Pentakis(dimethylamino)tantalum(V), also known as PDMAT or TADMA, is an organotantalum compound with the molecular formula C₁₀H₃₀N₅Ta and a molecular weight of 401.33 g/mol. The structure features tantalum in the +5 oxidation state, coordinated with five dimethylamino groups, making it highly reactive in synthesis. This light yellow to orange powder (99% pure by gravimetric assay) is sensitive to both air and moisture, necessitating storage in an inert, dry environment.
Applications in Organic and Inorganic Synthesis
Pentakis(dimethylamino)tantalum(V) is widely used in chemical vapor deposition (CVD) as a precursor for thin-film applications, especially in semiconductor manufacturing, where it enables precise layering of tantalum-based films.
Precautions for Safe Storage and Handling
Classified with hazard codes H228-2, H260, H314, and H318, PDMAT requires careful handling due to its water-reactive and flammable nature. It should be stored in airtight, inert gas containers, with protective gear necessary for safe handling.
Industrial and Laboratory Applications
PDMAT is essential in semiconductor and electronic component production. Its reactivity and stability make it an ideal precursor for creating high-purity tantalum nitride and oxide layers in advanced manufacturing processes.
PDMAT is used in the semiconductor industry for the deposition of tantalum nitride-based layers by atomic layer deposition (ALD). Also yields tantalum oxide (Ta2O5) thin films when O2, H2O, NO or H2O2 is present during the deposition process. Tantalum oxide thins films show promise as gate dielectric materials in the manufacture of integrated circuits. The synthesis of PDMAT is widely described in the literature (see the links below). Ereztech manufactures and sells this product in small and bulk volumes. Glass ampules, bottles or metal ampules or bubblers are available for packaging.
