The theoretical basis for improving the adhesion of the conducting layers of dielectric substrates

Electronics, Electronic Equipment Material ProductionTechnologies

The appearance of great pulling electric fields at anodic bonding process with a conductor surface turns out to be possible due to the interlayer polarization developing in ionic dielectric under the action of electric voltage. This results in a negative charge accumulation in a layer of small (several micrometers) thickness and adhesion enhancement. A physico-mathematical model of the join of ionic dielectric to a conductor is developed.
