Abstract

The laser initiated formation of Cd-deposits from dimethylcadmium (DMCd) on quartz substrates has been investigated at various wavelengths between 337 and 676 nm. In this range substrate and DMCd are both transparent. The deposition mechanism is initiated by multiphoton dissociation of DMCd molecules adsorbed at the glass substrate and continues by pyrolysis of DMCd molecules at the laser-heated metallic deposit. Metal structures with a resolution below 1 μm have been obtained.
