Yole: SiC rescues the power device market
Despite an overall power electronics 2012 downturn, silicon carbide kept on growing
Starting in late 2011, the power electronics downturn in 2012 was quite severe, exhibiting a 20 percent decline.
Yole Développement says this in its "SiC Market 2013: Technology and Market for SiC Wafers, Devices and Power Modules" report.
Yole's report focuses on the entire value-chain and covers all SiC applications in low, medium and high power ranges and provides all metrics up to 2020.
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 percent increase year over 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 the SiC diode business was the most buoyant due to micro-inverter applications. However Yole is 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 $75 million 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
Yole estimates 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. And Fuji Electric’s new SiC line is now running within the Japanese national program.
No Chinese device maker has emerged yet, however, according to the huge investment plan in R&D, Yole’s analyst suspects new IDMs will soon enter the business.
In the US, Global Power Device and USCi have now exited stealth mode and have strongly affirmed their intentions to take market share.
Ultimately, the unexpected closing down of SemiSouth in October 2012 has created chatter about the quite stable-until-then SiC business. Several reasons have been disclosed that explain this decision (over-sized company, market too long to take-off and so on), however Yole says we can’t ignore that it discredits to some extent the Noff JFET technology. Only the future will tell…
Reshaping from discretes to modules Yole now sees the SiC industry reshaping, starting from a discrete device business and now mutating into a power module business. Originally, this was initiated by Powerex, MicroSemi, Vincotech or GeneSiC with hybrid Si/SiC products, then other players such as Mitsubishi, GPE and more recently Rohm have reached the market with full-SiC modules.
This trend will become dominant in the coming years as integrators require power modules in most of their mid and high power systems (generally starting from >3kW).
Yole forecasts that SiC-based power module demand could exceed $100 million by 2015 and top about $800 million in 2020 depending on whether or not the auto industry will adopt SiC.
Next critical challenges: Cost reduction, packaging & multi-sourcing
SiC enables high frequency and high temperature operation. That said, capturing these 2 added-values remains an issue as no existing set of technologies can fully answer that request now. The path to success for SiC large implementation will need to go through new packaging solutions. Numerous bottlenecks need to be unlocked. These include chip bonding, metallic contact technique, gel filling, encapsulant and EMI.
Power device integrators generally rely on two, or even three sources to lower supply-chain risks. In SiC, it is now easy operating multi-sourcing for diodes, though not yet for transistors. MOSFET, JFET or BJT must be available from at least 2 companies with similar specifications.
