A novel SOI CBiCMOS compatible device structure for analog and mixed-mode circuits

A novel SOI CBiCMOS compatible structure has been developed which can be operated as both an MOS and lateral bipolar transistor. During the MOS operation, the new structure provides a very effective body contact to eliminate the floating-body effects such as I-V kink, low breakdown voltage and the anomalous subthreshold characteristics. In the bipolar mode, the structure provides a very efficient base contact with low base resistance compared to most existing base contact schemes.
