Optimization of the solution composition for laser-induced chemical liquid phase deposition of copper

Abstract

Optimal compositions of autocatalytic solutions for laser-induced deposition of copper were established. The copper salt concentration range in which the process gives the best results was determined. It is shown that optical microscopy, as a means of controlling the topology of the deposited structures, has limited applicability. The results obtained by this method should be verified by alternative techniques, e.g., electron microscopy or measurements of the electrical conductivity of deposited structures.
