Abstract

Communication: Aluminium microstructures, important in electronics packaging applications, can be efficiently produced using a new two-step method which involves thermal CVD from (trimethylamine)trihydridoaluminum onto lasergenerated spatially selective prenucleation patterns of a palladium catalyst. Interestingly, the aluminum continues to grow to heights of more than a few nanometers even after it has completely covered the palladium catalyst.
