Polylithic integration of true single chip radio using quartz-on-silicon wafer

Summary form only given. PLIC (polylithic integrated circuit) technology allows one to fabricate heterogeneous systems on a single wafer. In PLIC, various crystals are stacked vertically and different devices having optimum performance on each crystal, are fabricated then connected on the same wafer, all using IC fabrication technology. Then complete system is finally obtained as a single chip after dicing. Thus drastic reduction in cost and size and great improvement in performance and reliability are expected. In this presentation, PLIC using QoS (Quartz-on-Silicon) is taken as an example to demonstrate the feasibility of a true single chip radio, where RF and digital circuits, antenna, and electroacoustic filters are integrated on the same wafer
