The optimized conditions to obtain supple and monolithic interconnect in PM
DA-ODA polyimide are exposed here, by a dry process which makes use of ion
irradiations in the 100 keV energy range. The ohmic conditions for direct c
urrent conduction are determined. The electrical power dissipated along mil
limeter lines is studied. Equivalent electrical parameters for the direct c
urrent conduction are calculated. The real thickness of the surface conduct
ive layer is clearly determined by physical investigations. (C) 2001 Elsevi
