Abstract: Disclosed herein is a stripline interconnect system for high-frequency signal transmission. The interconnect is positioned within a recessed area of a substrate, enabling a reduced height. Included in this design is a dielectric ramp, manufactured on the substrate, that facilitates a smooth transition from transmission dielectric to height of the wafer. Formed using aerosol jet printing, a center conductor extends from the substrate, traverses the dielectric ramp, and connects to wafer pads. To provide for electromagnetic confinement and reduce external interferences, a dielectric is printed over the center conductor, forming an arch, which is subsequently shielded with a printed metal covering. This design provides for reduced insertion and reflection losses, low dispersion, and increased signal isolation. This stripline interconnect is of particular interest for applications desiring precise high-frequency signal transmission between integrated circuit wafers and external circuitry.
