Basic 3C SiC cubic wafer power electronics

Basic 3C Inc., a Longmont startup aiming to go to market soon with a new type of semiconductor, has added about $650,000 from existing investors to a Series A round of funding.

Basic 3C president Bart Van Zeghbroeck said this week that the hope is that the latest funds get the company through the next six months before raising a Series B.

Founded in April 2014, the company — based at 1830 Boston Ave. — has been in product-development mode, but is hoping to commercialize its first product in the next six months.

Basic 3C’s semiconductors will be made from cubic silicon carbide, rather than silicon. Geared toward high-power applications operating at 600 volts or more that require efficient power conversion, the product will have higher thermal conductivity and do well in “operationally rugged environments,” Van Zeghbroeck said. He said targeted applications include solar panels, wind turbines and electric vehicles. A reduced cooling requirement would mean reduced size and weight and thus, in something like an electric vehicle, improved efficiency and range.

“We’re looking at significantly better material properties, and that makes a difference in the end application,” Van Zeghbroeck said.

Investors in the company include Boulder-based Infield Capital and Texas-based Dankat LLC.

Van Zeghbroeck is on leave from the University of Colorado, where he has been an electrical engineering professor since 1990. He and investors purchased the technology and intellectual property for Basic 3C from a Golden company, Silicon Carbide Systems, that had gone bankrupt.

Van Zeghbroeck said Basic 3C will initially do manufacturing at its current space in Longmont. The company has fewer than 10 employees, but he said he expects that number to grow to 15 or 20 within the next 18 months.
