abstract = {The relation between surface preconditioning and metal
deposition in the direct galvanic metallization of different
insulating polymer surfaces by the so-called PLATO technique
was studied using electrochemical and surface analytical
methods. AFM, XPS and contact angle measurements show that
the chromic acid etching of original polymer surfaces leads
to an increase of the surface energy and hydrophilicity of
polymer substrates due to both surface roughening and the
formation of -COOH and/or -COH surface groups. However,
decisive for the subsequent surface activation with cobalt
sulfide is the increase in surface roughness. The influence
of the degree of activation and the electrode potential on
the kinetics of Ni metallization was studied by current
transient measurements on activated line-shaped structures.
The results suggest that the electrochemical reduction of
cobalt sulfide to cobalt is a necessary step to induce the
process of Ni electrodeposition. Successful Ni metallization
could be obtained on ABS (acrylonitrile-butadiene-styrene)
and PEEK (poly-ether-ether-ketone) surfaces. The lateral
propagation rate, V-x, of the depositing Ni layer depends
exponentially on the applied potential and was found to be
several orders of magnitude higher than the Ni deposition
rate, V-z, in the normal z-direction (V-x/V-z=10(2)-10(4)).
It was demonstrated that the approach involving cobalt
sulfide pre-activation can also be applied successfully for
metallization of oxidized porous silicon surfaces.},
