Microsemi enters SiC epiwafer supply agreement with SemiSouth

Microsemi Corp of Irvine, CA, USA and SemiSouth Laboratories Inc of Starkville, MS, USA have agreed to cooperate on silicon carbide epiwafer supply as well as certain technical exchanges.

SemiSouth, which was spun out of Mississippi State University (MSU) in 2000, specializes in SiC material and device fabrication. In August 2006, the firm opened its high-volume SiC epiwafer and power semiconductor fabrication plant, raised $5m in venture capital financing, and won a five-year Small Business Technology Transfer (STTR) Phase III contract (with an initial value of $3.95m) from the Air Force Research Laboratory, related to extending the design, fabrication, and reliability testing of SiC power devices toward military qualification and reproducible manufacturability .

Microsemi designs and manufactures analog mixed-signal ICs and high-reliability semiconductors which manage and control or regulate power, protect against transient voltage spikes, and transmit, receive, and amplify signals. The main markets include defense, commercial air, satellite, medical, notebook computers, LCD TVs, mobile, and connectivity applications.

“We are pleased to enter into a closer working relationship with SemiSouth,” says Russell Crecraft, Microsemi’s Power Products Group VP and general manager. “Microsemi’s requirements for SiC wafers will grow in the future and we expect that this agreement will help SemiSouth’s talented team of engineers to continue their progress toward highly manufacturable silicon carbide epitaxy.”

“At SemiSouth, our long-term goals have always been to enable the SiC power device market through high-quality SiC epitaxy wafers and devices,” says SemiSouth’s president Jeff Casady. “Microsemi has a great track record of supplying high performance power device products, and this agreement represents a great step forward for the SiC power electronics market.”
