Soitec acquires NOVASiC to strengthen the its silicon carbide wafer technology

Takeover of NOVASiC to speed up Soitecs Technology development and strengthening of the positioning in the automotive and industrial markets

NOVASiCs expertise in wafering, polishing and reclaiming complements Soitecs technology portfolio to deliver an optimal end product and the indUstrialization of SmartSiC, based on Soitec´s unique and patented technology

Bernin (Grenoble), France, November 30, 2021 – Soitec (Euronext Paris), a global leader in the development and manufacture of innovative semiconductor materials, acquires NOVASiC, an advanced technology company specializing in the polishing and preparation of wafers on silicon carbide (SiC). The takeover enables Soitec to advance the development of semiconductors for power supply systems in electromobility and industrial applications. The transaction is expected to close before the end of calendar year 2021.

In a strategic step to meet the needs of the automotive and industrial markets for performance and energy efficiency, Soitec is expanding its product portfolio beyond Silicon on Insulator (SOI) with silicon carbide. This crystal material enables higher performance, optimized design and lower environmental impact for the power electronics, making it particularly suitable for electric vehicles and other energy efficient applications.

SmartSiC ™ substrates, which result from the application of Soitec’s unique and patented proprietary technology SmartCut ™ on SiC, will achieve a new level of performance and energy efficiency compared to conventional silicon carbide bulk through higher reusability of donor wafers, improved yields and lower die -Sizes allow. SmartSiC ™ will not only reduce the environmental impact of silicon carbide in the production process, it will also act as a catalyst to accelerate the adoption of electric vehicles. SmartSiC ™ is currently at the device prototyping level with several key partners.

NOVASiC was founded in 1995 and offers laboratories and industrial customers state-of-the-art wafering, reclaim and polishing services for high-performance semiconductors and industrial crystals with a special focus on silicon carbide. The company has developed innovative polishing processes that enable improved device performance with a scratch-free, low roughness, ultra-clean epi-ready surface and no damaged layers.

With the takeover Didier Marsan, CEO of NOVASiC and international expert, will become Senior Technical Advisor for Soitec.

SoitecS. SmartSiC Substrates will be the backbone of energy-efficient electromobility,called Bernhard Asparagus, COO of Soitec. “The acquiredon from NOVASiC and the integration of its know-how in the areas of wafering, polishing and reclaiming brings Soitec the latest technology building block to deliver an optimal end product and the industrialization phase of our SmartSiC Range of products. The eExpertise from NOVASiC will help us further accelerate the time to market and rollout of our smart silicon carbide applications in the promising and demanding automotive and industrial markets.

We are very excited to become part of a leading global supplier of semiconductor mateRials like Soitec,called Didier Marsan, CEO of NOVASiC. We look forward to contributing our expertise to the Soitec. to supports new, very promising product line and a contribution to the introduction of Soitec´s intelligent silicon carbide solutions.
