QUEST FOR HIGH-QUALITY LOCAL ELECTROLESS LASER DEPOSITION FROM THE LIQUID-PHASE - DECOMPOSITION OF AMMONIUM MOLYBDATE

A systematic study on concentration (0.001-0.1M), laser power (up to 200 mW) and scanning speed (from 10 to 200 mum/s) dependence of pyrolytic laser decomposition of ammonium molybdate is reported. It is shown that there exists an optimal concentration range in which best quality deposition is observed and all the disadvantageous features typical for slow writing can significantly be improved by the increase of scanning speed. At speeds exceeding 0.1 mm/s well defined lines without macrostructure and of excellent morphology can be written and all the important characteristics of the lines remain virtually unchanged in a wide range of processing parameters.
