X-FAB and Soitec will begin work to offer Soitec’s SmartSiC™ wafers for the production of silicon carbide power devices at X-FAB’s plant in Lubbock, Texas.
This collaboration follows the successful completion of the assessment phase, during which silicon carbide (SiC) power devices were manufactured at X-FAB Texas on 150mm SmartSiC™ wafers. Soitec will offer X-FAB’s customers easy access to the SmartSiC™ substrate through a joint supply chain consignment model.
X-FAB is the pioneer and leader of the foundry model in the fast-growing SiC market. Silicon carbide (SiC) is a disruptive compound semiconductor material with intrinsic properties providing superior performance and efficiency over silicon in power applications.
SmartSiC™ is a proprietary Soitec technology based on the company’s SmartCut™ process, in which a thin layer of a high-quality monocrystalline (mono-SiC) ‘donor’ wafer is split off and bonded to a low resistivity polycrystalline (poly-SiC) ‘handle’ wafer. The resulting substrate offers improved device performance and manufacturing yields. The process allows multiple re-uses of a single donor wafer, significantly reducing cost and related CO2 emissions.In this fast-growing market, Soitec is ramping production of SmartSiC™ substrates at its new plant of Bernin, near Grenoble (France). X-FAB is increasing production capacity for SiC devices at the Lubbock plant. The use of the SmartSiC™ substrate enables X-FAB’s customers to design smaller devices, resulting in efficiency improvements through an increased number of dies per wafer. The benefit of reduced CO2 emissions from the substrate manufacturing process will also contribute to X-FAB’s initiative to reduce its overall carbon footprint.
Sophie Le-Guyadec VP Procurement of X-FAB, states: “As the leading SiC foundry, we want to provide our customers the full range of opportunities to design innovative and robust SiC devices for electric vehicles, renewable power and industrial applications. To offer the most advanced silicon carbide processes and manufacturing capabilities, we jointly agreed to provide our customers easy access to Soitec’s innovative SmartSiC™ via a consignment model.”
Emmanuel Sabonnadiere, Soitec Executive Vice President Automotive and Industry comments: “Soitec’s SmartSiC substrates and X-FAB’s foundry services are a perfect fit to meet increasing demand for new SiC products. This cooperation is a significant milestone for the deployment of SmartSiC in the U.S. market and internationally, thanks to X-FAB’s global footprint.”Original – X-FAB

X-FAB Silicon Foundries SE, the leading analog/mixed-signal and specialty foundry, has updated its XP018 high-voltage CMOS semiconductor fabrication platform with new 40V and 60V high-voltage primitive devices, which feature an extended SOA for improved operational robustness.
These 2nd generation high-voltage primitive devices exhibit up to a 50% reduction in RDSon figures compared to the previous version. This offers an alternative which is better positioned to address certain key applications – particularly where devices’ footprints need to be reduced and unit costs minimized.
The XP018 platform is a modular 180nm high-voltage EPI technology solution, based on a low mask count 5V single-gate core module. It supports an extended temperature range of -40 to 175°C and offers a wide range of optional devices and modules, including high-gain bipolar devices, standard and high-capacitance MIM capacitors, multi-threshold (Vt) options, Schottky diodes, and depletion devices.
The platform is supported by high-reliability automotive NVM solutions, such as embedded Flash, EEPROM, and OTP, making it specifically designed for cost-sensitive and robust automotive, industrial, and medical applications.
In addition to the new 40V/60V devices, the platform has been enhanced by the inclusion of 5.3V Zener diodes. The new low leakage Zener diode is designed to effectively protect the gate oxide in critical applications, such as Wide Bandgap gate driver applications. Furthermore, there are also new isolated drain high-voltage devices up to 24V and a new 1.8 V medium Vt option on offer.
Tilman Metzger, Product Line Manager for High-Voltage at X-FAB, comments: “With this update of our XP018 platform we are demonstrating X-FAB’s commitment to enhancing established technologies. XP018 has been in production for more than a decade and still sees widespread adoption for new designs from our focus market segments: automotive, industrial and medical. The new competitive high-voltage devices and updates will enable our customers to implement more innovative and cost-effective products. Designers utilizing the new XP018 primitive devices have access to comprehensive PDK support across major EDA platforms like Cadence, Siemens EDA, Synopsys, ensuring seamless integration and optimization for a range of applications.”
A new medium Vt standard cell library is scheduled to be released in Q3 2024. Further details on the XP018 platform can be accessed by going to: www.xfab.com/technology/high-voltage
