Descrição geral

Trimethylaluminum (TMA) is the most reactive and volatile among all organoaluminium compounds. It is extremely pyrophoric. It acts as a highly reactive reducing and alkylating agent.

Aplicação

TMA is used in a Ziegler Natta catalyst for polymerization and hydrogenation. TMA is mainly used for the production of methylaluminoxane, such as metalorganic chemical vapor deposition (MOCVD) of:
  • Al2O3 using TMA and O2 precursors.
  • Al4C3 layers have been grown on Al2O3 (0001) using TMA and methane as source materials for aluminum and carbon.

Atomic Layer Deposition (ALD) — A Versatile Tool for Nanostructuring

Some of the most innovative uses for atomic layer deposition (ALD) include synthesis of novel structures, area-selective deposition of materials, low-temperature ALD deposition, and temperature-sensitive subtrates.

Tutorial in Microelectronics and Nanoelectronics

As the electronic industry continues to move towards smaller and smaller devices, researchers must continually strive for technologies to deposit electronic materials with precision at ever-smaller scales. This trend has lead to a variety of techniques used in the microelectronics industry to layer materials with precision thicknesses, sometimes down to even the atomic level.
