Fabrication of Passive Elements using Ink-Jet Technology

Abstract

A novel process has been developed to print passive elements like resistors, capacitors and inductors using demand mode ink-jet technology. The process involves printing intrinsically conductive polymer, thermosetting resin system loaded with conductive particles, ferrite-powders in thermosetting resin matrix, or liquid metals using drop-ondemand printheads and a precision printing platform. The same printing technique can also be used to enhance the yield of current embedded resistor processes by trimming resistor down (reduce the resistance) using intrinsically conductive polymer.
