Abstract
The invention relates to a method for obtaining a metal contact on a substrate, comprising the following steps: (a) depositing a metal pattern in the form of a paste formed from a mixture of a metal power and a solvent, (b) heating the assembly formed in step (a) in order to evaporate the solvent, and (c) annealing same in order to form a metal contact between the metal pattern and the substrate. The invention is characterised in that it also includes a step (d) in which the metal contact is heated by laser at an energy density of between 0.5 J/cm2 and 15 J/cm2.
