General description

Please inquire for bulk quantity, pricing, and packaging options.

Application

Tetrakis(dimethylamido)titanium(IV) (TDMAT) is a precursor to titanium nitride (TiN) thin films by organometallic chemical vapor deposition (OMCVD)and titanium dioxide thin films by atomic layer deposition (ALD).TDMAT undergoes exothermal reaction with excess cyclopentadiene to yield tris(dimethylamido)(η5-cyclopentadienyl)titanium(IV).
