General description

Tetrakis(dimethylamido)titanium(IV) [Ti(N(CH₃)₂)₄], or TDMAT, is a volatile, colourless to pale yellow liquid. Its high volatility and thermal stability make it suitable for chemical vapor deposition (CVD) and atomic layer deposition (ALD), enabling the controlled deposition of titanium-based films such as titanium nitride (TiN) and titanium dioxide (TiO₂). It also supports uniform film growth at low temperatures, making it compatible with temperature-sensitive substrates

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).

Features and Benefits

  • 99.999% trace metals basis ensures superior quality of deposited films, with minimal defects and consistent properties, critical for microelectronics and optoelectronics applications.
  • High purity reduces the risk of contamination during the coating process, leading to enhanced adhesion, durability, and performance of the final products.
  • The absence of impurities allows for the precise control of particle size and morphology, improving the effectiveness of nanoparticles in targeted applications.
  • High purity ensures that electronic properties are not compromised by impurities, enhancing device performance and reliability.
  • Controlling heavy metals at ppb levels ensures effective contamination control, regulatory compliance, and optimized performance.
