Trimethylindium

Description:
Trimethylindium (TMI) is an organometallic compound with the formula In(CH₃)₃. It is characterized by its volatility and reactivity, making it a valuable precursor in the field of semiconductor manufacturing, particularly for the deposition of indium-containing thin films. TMI is a colorless to pale yellow liquid at room temperature and has a relatively low boiling point, which facilitates its use in chemical vapor deposition (CVD) processes. The compound is highly sensitive to moisture and air, leading to hydrolysis and oxidation, which can produce indium oxides or hydroxides. Due to its organometallic nature, TMI exhibits a tetrahedral geometry around the indium atom, with the three methyl groups providing steric bulk. Safety precautions are essential when handling TMI, as it is toxic and can pose health risks upon exposure. Proper storage in inert atmospheres and the use of appropriate personal protective equipment are crucial to mitigate these risks. Overall, trimethylindium is an important compound in materials science and electronics, particularly in the development of advanced semiconductor devices.
