Value Proposition

Clas-SiC

Dedicated Silicon
Carbide foundry

Clas-SiC

Accelerate R&D
cycle times

Clas-SiC

Scale to medium
rate production

Clas-SiC is unique in offering circa 4 week cycle times for Diode level SiC wafer processing to accelerate R & D and time to market for new device designs.

Mosfets & Switches are targeted at 8 weeks for R & D lots. Clas-SiC has invested in medium scale SiC production capacity to not only deliver time to market advantage but also time to profit as customer R & D is supported by over 200 man-years of Silicon Carbide processing expertise and a suite or library of “off the shelf” Process Module IP blocks to minimise technical risk and optimise R & D cycles to include design for manufacture principles from the outset.

Carl founded II-VI Incorporated (Saxonburg, Pennsylvania USA) in 1971 to develop and manufacture II-VI compound semiconductor materials for optics and electro-optical applications in the then emerging, high-power laser arena. He served the company as its Principal Executive Officer and a Director for 36 years and continued as its Board Chairman for an additional 7 years.

During his career at II-VI, Carl oversaw and participated in or helped motivate company efforts to:

  • Develop and deploy the commercial scale manufacturing of highest-quality, laser-grade Cadmium Telluride (1971), Zinc Selenide (1975), Zinc Sulfide (1985) and diamond (2004)
  • Develop and deploy the commercial scale manufacturing of highest-quality, electronic-grade 3 inch, 100 mm and 150 mm diameter Silicon Carbide substrates (2000)
  • Since 2007, Carl has been active as a Primary Equity Investor in 3 startup/emerging, technology-based businesses and serves as Board Chairman for each of those entities.
  • Carl attained a Bachelors Degree from Purdue University (USA) in 1964, the Masters Degree from Massachusetts Institute of Technology (USA) in 1965, and a Ph.D. Degree from the University of Illinois (USA) in 1969, all in the field of Electrical Engineering.

JD Brookhart, a managing director at CJ&M Holdings, holds a finance degree from Colorado State University. He began his career as an award winning sales executive at Xerox and was recruited to advance his career in medical equipment sales and then engineering software sales. He made a life-changing decision and spent the next 18 years coaching football in the NFL and at the highest level of college. He was a coordinator and head coach at a number of prestigious schools. He now directs CJ&M Holdings and their pursuit of supporting start-up companies. JD also serves as a Board member for several for profit and non-profit entities. He lives in Denver, Colorado with his wife and 4 sons.
