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 2 00 mW) and scanning speed (from 10 to 200 mum/s) dependence of pyrolyt ic 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 f or slow writing can significantly be improved by the increase of scann ing speed. At speeds exceeding 0.1 mm/s well defined lines without mac rostructure and of excellent morphology can be written and all the imp ortant characteristics of the lines remain virtually unchanged in a wi de range of processing parameters.
