Paper Abstract

Patterns of electrically conducting polymers (100 S cm-1) can be obtained by irradiating thin layers of insulating poly (bis-ethylthio-acetylene) (10-14 S cm-1) with 488 nm Ar+-laser or 351 nm XeF-excimer laser radiation. On the other hand this polymer is a suitable material for laser-induced ablation (photodecomposition), whereby this excimer laser patterned insulating polymer can be made conductive by another Ar+-laser afterwards. The conducting tracks have a stable resistivity both in air (without encapsulation) and in moisture at various temperatures and even in corrosive atmospheres. With these techniques, using a computer-controlled linear positioning system, printed microcircuit boards with integrated passive electronic components can be obtained. Surface mounted devices may be integrated into such circuitry using conductive adhesives.
