WebTEMAH is used as a precursor for atomic layer deposition (ALD)of hafnium oxide (HfO 2) thin films. Because HfO 2 has a high dielectric constant of 16-25, it is commonly used as a dielectric film in semiconductor fabrication. TEMAH is ideal for ALD because of its low boiling point and its reactivity with water and ozone.
