Abstract :
A base and drain merged bipolar-PMOSFET (BiPMOS) structure was examined. A latch-up phenomenon in this structure associated with a parasitic PNP bipolar was investigated and verified experimentally and analytically. From the standpoint of stability in circuit operation a latch-up-free structure was considered. To evaluate the contribution of this technology to circuit speed performance, the structure was applied to a BiNMOS gate. It was found that the delay time if a merged BiNMOS gate was improved by 10-20% compared with that of the conventional BiNMOS gate. Moreover, at a fan-out of 1, this gate achieved a higher speed than the CMOS gate.<>
