Displacement of silicon has already begun...




Despite overall power electronics 2012 downturn, SiC kept on growing

Started late in 2011, the power electronics downturn in 2012 was quite severe, exhibiting -20% negative growth. The market suffered from the global economic downturn combined with external factors like China controlling what happened in some selected markets (Wind turbine or Rail traction projects that have been stopped or postponed).

However, the SiC device market kept on growing with a +38% increase year to year.

SiC technology is now commonly accepted as a reliable and pertinent alternative to the silicon world. Most power module and power inverter manufacturers have already included it in their roadmap as an option or as a firm project. However time-to-market differs from application to application as a function of value proposals for cost, specifications, availability and so on….

Despite a quite depressed market last year, PV inverters have proven their appetite for SiC devices in 2012. They are the biggest consumer of SiC devices together with PFCs.

In 2011 and 2012 SiC diode business was the most buoyancy due to micro-inverter applications, however we are confident that both JFET and MOSFET will quickly catch-up and become dominant in revenue by 2016.

SiC device (bare-dies or packaged discretes) market reached about $75M in 2012 with a sharp domination by Infineon and CREE again, however the competition is little by little grabbing market share with STMicroelectronics and Rohm closing the loop.






30 contenders, half-a-dozen of new entrants, 1 dead

There are now more than 30 companies worldwide which have established a dedicated SiC device manufacturing capability with related commercial and promotion activities. Virtually, all other existing Silicon-based power device makers are also more or less active in the SiC market but at different stages.

2012 has seen the ramp-up of some companies, such as Rohm, MicroSemi, GeneSiC or STMicro, facing the 2 giants CREE and Infineon, prefiguring a new market shaping in the coming years.

Four new companies - Raytheon, Ascatron, IBS and Fraunhofer IISB - have decided, almost simultaneously, to launch SiC foundry services or contract manufacturing services. This business model establishment addresses the demand of future SiC fabless and design houses that may look for specific manufacturing partners. It will also probably act as a possible second source for IDMs in cases of production overshoot.

In Asia, Panasonic and Toshiba are now clearly identified as credible contenders, along with Mitsubishi Electric, now developing SiC power modules. Fuji Electric’s new SiC line is now running within the Japanese national program.
