Fabrication of Metallization by Laser Sintering of Micro Powders

Abstract

In this paper, a method of producing the metallization on the alumina ceramic substrate by micropowders of ruthenium dioxide sintering using laser radiation with 10.6 micrometers length (carbon dioxide laser) is described. During the work parameters of the mask, allowing to reduce the width of the laser spot as well as to get a mildly sloping profile of the radiation intensity, due to which more uniform sintering of the powders and pastes based on them takes place, are calculated.
