Microstrip-to-microstrip interconnects with adhesive bonded ribbons for micro- and millimeterwave applications

A simple chip-to-chip interconnect technique with adhesive bonded ribbons is presented. It solves the insertion loss problem of wire bond interconnects in micro- and millimeterwave assemblies. The following paper discusses design and fabrication of such interconnects. A quasistatic model is developed to ease the quality assessment of their electrical behavior. It is validated by measurements on microstrip resonators with and without interconnects. The chip-to-chip interconnect technique with adhesive bonded ribbons exhibit low loss and is useable up to 50 GHz or more.
