ABSTRACT
A process for preparing vertical interconnects for flexible electronics using transfer printing is reported. The interconnects are initially prepared on a sacrificial transfer substrate in a four step process that yields a subassembly of upper electrode, interconnect, and dielectric. This subassembly is printed as a unit onto the lower electrodes. The average contact resistance is less than 1 Ω/25 μm2 interconnect cross section. The quality of the resulting conductive paths is established by fabricating and characterizing (to 5 GHz) the inductances and quality factors of a series of square planar spiral inductors.
