โœฆ Synopsis


We have developed 0.8 m SOI BiCDMOS process that includes di!erent types of devices like 35 V Bipolar, 5 V CMOS and 60 V LDMOS. The devices are fabricated on an SOI (Silicon on Insulator) and separated by trench technology to be completely isolated by dielectric oxide. This technology can prevent the formation of any parasitic bipolar transistors which have been the cause of device failures with the conventional junction isolation under the severe environment of automotive application. This technology is one of the most suitable mixed process ICs for vehicles. This report introduces an overview of the process and ICs.
