X-FAB and Soitec team up on SmartSiC
Partnership to bring power devices based on Soitec’s SmartSiC wafers to X-FAB’s fabless customers
X-FAB and semiconductor materials firm Soitec will work to offer Soitec’s SmartSiC wafers for the production of SiC power devices at X-FAB’s plant in Lubbock, Texas.
This collaboration follows the successful completion of the assessment phase, during which SiC (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.
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 SiC 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 VP 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.”
Secure Your Hydrogen Supply
A study supply of high-purity hydrogen is critical to semiconductor fabrication. Supply chain interruptions are challenging manufacturers, leading to production slowdowns and stoppages. On-site hydrogen generation offers a scalable alternative for new and existing fabs, freeing the operator from dependence on delivered gas.Plant managers understand the critical role that hydrogen plays in semiconductor fabrication. That important job includes crystal growth, carrier gas, wafer annealing, and in the emerging Extreme UV Lithography (EUV) that will enable new generations of devices. As the vast need for semiconductors grows across all sectors of world economies, so does the need for high-purity hydrogen.
