Abstract

The laser-induced deposition of high purity aluminum is achieved by the pyrolytic decomposition of the aluminum hydride-trimethylamine complex. The nonpyrophoricity and substantial vapor pressure of this aluminum precursor makes it ideal for the rapid deposition of pure aluminum metal. This is a vast improvement over other aluminum alkyl complexes which are either relatively nonvolatile (i.e., triisobutyl aluminum) or decompose to carbon contaminated aluminum films (i.e., trimethyl aluminum).
