Look Towards A New Future

Power GaN 2012

The GaN power device industry has probably generated less than $2.5M revenues in 2011, as only 2 companies (IRF & EPC Corp.) are selling products on the open market. However, the overall GaN activity has seen extra revenues as R&D contracts, qualification tests and sampling for qualified customers was extremely buoyant.

At very short term, IRF and EPC will likely remain the two main vendors of GaN power devices on the open market in early 2012. This market is likely to stay below $10M for devices, with the rest being made through R&D sales.

2013 should signal the transition from qualification to production ramp-up for several new entrants.The device market could reach the $50M threshold. In 2014, most of these new entrants will ramp-up their capacity, and by 2015 the availability and adoption of qualified 600V+ GaN devices should see the market grow very quickly, and open doors to non-consumer applications. In 2015, 12-15 players will share the consumption of more than 100,000 x 6” (equiv.) epiwafers.

Power device makers usually buy polished Silicon wafers, conduct the epi (or buy Si epi-wafers) if needed (FZ thin wafer doesn’t require epitaxy) then process the devices. This model is roughly the same for SiC technology.

For those who plan to enter in the GaN field, 2 scenarios could occur:
  • Some may not integrate MOCVD GaN epitaxy. They will buy GaN epiwafers and process it in the existing CMOS Front-End lines, as they use to do with Silicon substrates (or SiC).
  • Some will try to fully integrate the GaN process, from the bare silicon, the GaN epi and the Front-End.
This report provides a complete analysis of the GaN device and substrate industry in the power electronics field along with key market metrics. It provides company involvement as well as technology state-of-the-art. In addition, an extensive review of the possible substrates for GaN is provided, offering the most complete view of the Power GaN industry available to date.

Beyond that, if GaN is qualified in the EV/HEV sector, GaN device business could top the billion dollar line and the GaN-on-Si substrate market could exceed $300M revenues by 2019. However, it is still unclear how car makers will choose between SiC, GaN or the current Silicon technology. At the substrate end, R&D activities are still quite fragmented between several options involving
GaN-on-Sapphire, GaN-on-SiC, GaN-on-GaN, GaN-on-AlN and GaN-on-Silicon. Nevertheless, GaNon-Si is likely to take a dominant position as 6” is now available with more than 7μm thick GaN epi and 8” is under qualification. 8” diameter availability is probably the parameter that will make this technology choice obvious.
It is now obvious that the GaN power world attracts numerous newcomers. We have screened 5 companies positioned on the epiwafer business side and more than 6 GaN device pure-players, aside to another 15 Si-based power firms developing GaN technology.

A new trend is LED players now starting looking at this new business opportunity and wondering how to put in place a strategy of diversification to convert their existing extra LED capacity into power. That represents an “epsilon” today, but we assume it may create some disturbances in the natural and organic expected growth…
GaN power electronics past, present and future business is inseparable to the LED industry. Both are linked in technology and market dynamics.
In the past, the premises of GaN epi technology came from the LED industry that has brought this technology from the labs to mass production.
Today, the extensive developments of GaN-on-Si epiwafers fertilized both the LED and the Power industry. Most of the epiwafer vendors are targeting these 2 segments with dedicated products and offers.
Tomorrow, it is likely some incumbent LED pure-players will enter in the Power industry world, using their extra-capacity and existing tool-sets to make, at least epiwafers, or even power devices.
