Abstract :
A new MM-wave IC concept consisting of flip-chip bonded MM-wave transistors on microstrip lines formed on a Si substrate and its key technologies are introduced. By using benzocyclobutene (BCB) dielectric, the insertion loss of microstrip lines has been reduced to less than 1/3 as compared with that of the conventional SiO2 based one, and the influence of the bonding pad has also been decreased. A 50 GHz HBT amplifier and a 30 GHz HFET/HBT receiver front-end IC are demonstrated as examples of MFIC applications. Results show that MFICs using BCB dielectric and micro bump bonding (MBB) technology have performance and designability suitable for the MM-wave band
