When you’re at a party, you may dread being asked what you do. Often, saying that you work in the compound semiconductor industry will kill the conversation dead, because the person that you are talking to will have little idea of what you do. All they will grasp is that it is very technical.
What they will fail to appreciate, but you as an insider know, is that the CS industry is certainly not a niche, but a rather large collection of them: power electronics, RF devices, lasers, long- wavelength detectors and so on.
What holds all of these disparate sectors together is the way we make our devices: nearly every chip that we produce involves the growth of crystalline layers, either by MOCVD or MBE.
One of the leading manufacturers of MOCVD tools is Aixtron. This German outfit has traditionally taken the largest share of reactor sales, but in recent times Veeco has pulled ahead, thanks to greater success in China. Aixtron’s new boss, Martin Goetzeler, is planning to take the company back to its leadership position, while improving the balance sheet, and on page 33 you can read his interview with this magazine.
In this issue, you can also learn about the development of reactors at the Japanese firm Taiyo Nippon Sanso. This company has traditionally focused on its domestic market,

but now seems to be striving for a more global presence. Another of this firm’s aims is to promote its tools for the growth of power electronic devices and ultraviolet LEDs. Both markets are still in their infancy, but have the potential to drive an increase in reactor sales, which should also get a boost from the uptake of solid-state lighting.
At present, MOCVD manufacturers are still suffering from overcapacity in the LED market, which followed the boom years of 2010 and 2011. But hopefully order visibility will soon improve, with sales taking a steady, maintainable upward path that will enable a healthy business for tool makers, which is ultimately good for all of us.
