Adding CMOS integration option to galvanic isolation solution

08-11-2023 | X-FAB | Semiconductors

X-FAB Silicon Foundries SE makes further significant progress with its galvanic isolation technology. Building on the 2018 introduction of its advanced process optimised for robust discrete capacitive or inductive couplers, the process can bring existing galvanic isolation elements directly together with active circuits based on its XA035 technology. This integrated approach permits more flexibility in the design of isolation products, managing emerging opportunities in renewable energy, EV powertrains, factory automation, and industrial power.

Based on a 350nm process node, XA035 is ideal for fabricating automotive sensors and high-voltage industrial devices. The high-voltage signal isolation capabilities it now supports mean long-term operational performance is sustained, even in demanding environments. It will facilitate the manufacture of robust components that are AEC-Q100 Grade 0 compliant and industrial-rated, such as digital isolators, isolated gate drivers, and isolated amplifier ICs. The company supplies a comprehensive PDK that supports the new and improved process technology for all major EDA vendors.

“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. We are also excited to see the first integrated customer products nearing production.”
