Description
- General description: Tetrakis(dimethylamido)hafnium(IV) is an organometallic compound consisting of a central hafnium atom (Hf) surrounded by four dimethylamido ligands (NMe2). It is commonly used as a CVD/ALD precursor to produce high-quality Hf thin films. It is a solid with low melting point.
- Application: Tetrakis(dimethylamido)hafnium(IV) can be used:As an atomic layer deposition(ALD) precursor for deposition of hafnium oxide thin films for advanced semiconductor devices.[1]As a precursor to fabricate polymer-derived ceramic nanocomposites.[2]To prepare HfO2, CeO2, and Ce-doped HfO2 thin films on Ge substrates by using tris(isopropyl-cyclopentadienyl)cerium [Ce(iPrCp)3] precursors with H2O via ALD method.[3]To produce Hf3N4 thin films with TDMAH and ammonia at low substrate temperatures at 150−250 °C.[4]
- Analysis Note: Purity excludes ~2000 ppm Zr.
