Abstract
A lateral bipolar transistor for an intergrated circuit is provided that maintains a high current gain and high frequency capability without sacrificing high Early voltage. More particularly, a lateral bipolar transistor is formed on an integrated circuit having both bipolar and CMOS devices, the lateral bipolar transistor being formed according to the BiCMOS method and without additional steps relative to formation of vertical bipolar devices if provided in the same area. Among other things, an integrated circuit is provided in which P well structures are provided in the collector regions of an LPNP that have been found to affect a significant increase in the product of the Early voltage and the current gain.
