X-Fab Silicon Foundries has made it possible to put galvanic isolation based on capacitive coupling into chips made on its XA035 process.
Based on a 350nm process node, XA035 is designed to cater for automotive sensors and high-voltage industrial devices. The addition of high-voltage isolation is meant to improve reliability in harsh environments with less need for external protection. X-Fab says the galvanic-isolation option will enable the manufacture of robust components that are AEC-Q100 Grade 0 compliant and the module is supported by a PDK.
“We see a growing demand from our customers for robust foundry solutions to design galvanically isolated products. X-Fab has been in production for several years with its proven high-reliable isolation layer for discrete coupler implementations,” states Tilman Metzger, marketing manager for high-voltage products at X-FAB. “By leveraging the very same process module, we are now able to offer even more flexibility in designing such products by enabling the direct integration with CMOS circuits on the same die.”
