Abstract :
This paper proposes a detailed comparison between three guard ring architectures designed in a BiCMOS process to minimize substrate cross-talk currents injected by a power vertical DMOS switch. The proposed structures consist of isolator and collector regions placed into a p-epi layer at different locations between the power device and the surrounding CMOS structures. Results show that collector guard ring efficiency is improved using a deep and large n-type implanted region preferably located close to the device to protect.
