Abstract(in English) | OE-COF packaging technology, including flip-chip bonded optical devices and LSIs on the optical waveguide film with impedance-matched electrical lines, was developed for over 10-Gbit/s transceiver modules. Self-aligned, mechanically reliable OE-COF was achieved by developing low-thermal-expansion OE film whose expansion coefficient was 1/6 that of the original OE film. Good optical interconnection characteristics were obtained by reducing of the optical return noise using refractive index matching cement between flip-chip bonded VCSEL and OE film surface. To evaluate the reliability of the Au-Sn solder bump connection, the thermal-shock test of -55℃-+125℃ was carried out. As a result, there was no change in the bonding strength after 1000 cycles, and it was confirmed to have a high thermal shock resistance. Impedance-matched copper co-planer waveguides formed on the surface of the OE film have -3 dB band width of 40GHz or more. |
