摘要

Electrophoretic deposition (EPD) is a low cost, particle based, electrodynamic forming process suitable forrnparticles in the micron to nanometer size range. It can be used to reproduce patterns of conductor or dielectricrnmaterial with micron scale resolution. This can be applied to the miniaturization of interconnects and componentsrnincorporated into low temperature co-fired ceramic modules.rnThe process for forming these patterns is as follows. First, a conductive pattern is imaged by conventionalrnphotolithography on a plastic film. This pattern can then be coated with particles by EPD. Using a binder, thisrndeposited particulate pattern can be transferred to another surface, where it can be sintered or fused to makerncontinuous conductor lines, dielectric patches or layers with micron scale vias. The photolithographically producedrnconductor pattern can then be re-used repeatedly to create more patterned particulate depositions. In this manner arnsingle pattern produced by photolithography can be used to make multiple parts with photolithographic scalernresolution. Using this process we have created 5 μm wide silver conductor lines on a 10 μm spacing, layers with 5rnμm diameter vias, and 600 nm thick barium titanate dielectric layers.
