WebTiCl4 for TiN, TEMAHf for HfN, were reacted with NH3 to grow ALD metal nitride films [10]. HfSiN films were deposited from TEMAHf/Si precursors using the precursor co-injection ALD technique [7] with alternating pulses of NH3. Work functions of these metal gates were extracted from measurements of MOSCAPs. Transistor devices using various WebTEMAHf Share Tetrakis (ethylmethylamido)hafnium (TEMAHf) is a liquid source material for ALD of the high-k gate rielectric such as HfO2 and HfxNy.
