High Voltage Complementary Epi Free LDMOS Module with 70 V PLDMOS for a 0.25 μm SiGe:C BiCMOS Platform

We demonstrate the integration of a low-cost, high-voltage complementary LDMOS module with BVdss of -71V and 83V for the PLDMOS and the NLDMOS, respectively, into an advanced industrial 0.25 mum SiGe:C BICMOS process. The essential deep N-well for the high voltage PLDMOS is formed by a single 6MeV P implantation step. BVdss*ft of the NLDMOS accomplishes record values > 900 VGHz.
