TMA (Trimethylaluminium)

Trimethylaluminium (TMA) is an organometallic compound composed of aluminum and organic methyl groups. It’s a highly reactive, oily liquid used mainly in the electronics industry to deposit thin films of materials like aluminum oxide through a process called chemical vapor deposition. TMA aggressively reacts with moisture in the air, so it must be handled with care under controlled conditions. Its primary role is to serve as a precursor in manufacturing advanced electronic devices, ensuring precise and high-quality coatings essential for the performance of semiconductors and other high-tech components.
