Soitec and Tokai Carbon to develop polycrystalline SiC substrates

Soitec and Tokai Carbon  have entered into a strategic partnership for the development and supply of polycrystalline silicon carbide substrates specifically designed for Soitec SmartSiC wafers.

        

Silicon carbide is a disruptive compound semiconductor. SmartSiC-engineered substrates accelerate the adoption of silicon carbide for electric mobility, industrial and smart grid applications by delivering superior manufacturing and cost efficiencies with an improved environmental footprint.

Under this partnership, which will see Tokai Carbon supply 150mm and 200mm poly-SiC wafers to Soitec, the two companies are harnessing their advanced R&D capabilities to enhance the SmartSiC ecosystem. 

Tokai Carbon’s advanced technology and manufacturing capacity in polycrystalline silicon carbide (polySiC) combined with the right to use Soitec specifications for polySiC coarse wafers compliant with Soitec SmartSiC is expected to make a strategic contribution to the global ramp-up of SmartSiC wafer production.

Cyril Menon, COO, Soitec, stated: “This partnership with Tokai marks yet another key step in the ramp-up of Soitec’s SmartSiC technology to address fast-growing markets such as electric mobility and industrial electrification. Tokai’s top quality SiC products and R&D capabilities, combined with Soitec’s innovative SmartSiC technology, can help to accelerate global adoption of electric mobility and other SiC technologies. This is an important milestone in terms of perception and value creation for SmartSiC ecosystem.”

Hajime Nagasaka, CEO of Tokai Carbon, commented: “The polycrystalline SiC substrate to be supplied to Soitec is a strategic product in our solid SiC product series. We are pleased to see our long years of research and development come to fruition in this way. We have high expectations for this product in the SiC semiconductor market, which is expected to expand significantly in the future. The partnership with Soitec is also very meaningful in terms of contributing to the realization of a sustainable society.”
