General description

Tetrakis(ethylmethylamino)zirconium (TEMAZ or TEMAZr) is a colorless, thermally stable organozirconium MOCVD compound. It is soluble in non-polar solvents such as petroleum ether and dichloromethane, but insoluble in water. TEMAZ is widely used as a zirconium precursor in semiconductor manufacturing. We provide it with ≥99.99% purity on a trace metals basis, ensuring ppb-level trace metal impurities, making it suitable for high-quality thin films.

Application

Tetrakis(ethylmethylamido)zirconium(IV) is used
  • As a Zirconium precursor in atomic layer deposition (ALD) to create ZrO₂ nanocoatings on cathode-active materials, enhancing interfacial stability and electrochemical performance in solid-state battery applications.
  • As an organometallic precursor in low-temperature solution processing to synthesize chalcogenide perovskite films, facilitating the formation of carbon-free, oxygen-free BaZrS₃ for optoelectronic applications.
  • As a precursor in plasma-enhanced atomic layer deposition to fabricate high-quality ZrO₂-containing HfₓZr₁₋ₓO₂ thin films, for advanced ferroelectric memory device applications.
We also provide the same materials in 10 g quantities, packaged in stainless steel cylinders(725528).

Features and Benefits

  • High-purity (≥99.99% trace metals basis) precursors to prevent impurities from affecting film properties.
  • Analyzing 32+ elements at ppb levels ensures suitability for forming uniform films in semiconductor applications.
  • Offers <10 ppm chloride by ion chromatography, crucial for high-quality films in semiconductor applications. Chloride can adversely affect film quality by altering composition, increasing surface roughness, introducing defects that degrade electrical performance, and impairing adhesion, leading to delamination or cracking.
