Electroless copper metallization of polyphenylquinoxaline (PPQ) was ca
rried out using a palladium acetyl acetonate (Pd(acac)2) precursor. A
continuous wave Ar ion laser was used to decompose the Pd(acac)2 organ
ometallic layer deposited onto the PPQ. The samples were then processe
d in a copper electroless plating solution of conventional composition
. The sample surfaces were analysed by X-ray photoelectron spectroscop
y before any treatment, after laser irradiation and at the very first
stages of copper growth. An estimate of the temperature reached by the
polymer under the laser beam was obtained by analysing the interferen
ce pattern reflected by the surface. Breakdown fields of the polymer d
ielectric were found in the region of 1 MV cm-1 and are weakly affecte
d by the electrochemical processes.
