This paper examines the feasibility of implementing transmission lines in a commercially-available SiGe HBT BiCMOS technology. Thin film microstrip transmission lines, using the top and bottom metalization layers (with a 3.24 /spl mu/m separation), from a 4 layer metal process SiGe HBT technology were designed, fabricated, and measured up to 110 GHz.

Titania (TiO2) powder, which is material for photoelectrode in dye-sensitized solar cells (DSSCs), was fabricated by hydrothermal synthesis process at 230 degrees C for 12 hours. The crystal structures of all the synthesized nano-structured TiO2 films exhibited anatase phase. Binder-free pastes were prepared with the change of the amount of ammonia water(More)
