A novel device structure and simple process technology for
realizing low-power/high-performance SOI lateral BJTs are presented. Low
base resistance has been achieved by employing a self-aligned external
base formation process. Due to reduced parasitics, the fabricated device
exhibited an fmax of 31 GHz, the highest value for an SOI BJT
reported so far
