Last week, El Segundo, Calif.-based Efficient Power Conversion, announced that its offering two types of power transistors made from gallium nitride that it has priced cheaper than their silicon counterparts. “This is the first time that something has really been higher performance and lower cost than silicon,” CEO Alex Lidow says. “Gallium nitride has taken the torch and is now running with it.”

Alex Lidow, CEO and co-founder of EPC, talks with Alix Palutre of Power Systems Design on a new family of eGaN FETs that has superior performance, smaller size, high reliability, and a low price point. With this announcement, the last barrier to the widespread adoption of GaN transistors as silicon MOSFET replacements has fallen.

Alex Lidow, the CEO of Efficient Power Conversion has made it his life’s work to prolong the lifespan of Moore’s Law. How? As Intel and others have found, traditional chip technology which relies on silicon is approaching a ceiling — pretty soon, somebody is going to make a silicon chip that is as cheap and powerful as that material allows. Lidow says he’s found a semiconducting material that is superior to silicon in many ways: gallium nitride (GaN). Both in laboratories and in practice, GaN chips have outperformed silicon in a number of use cases and are also cheaper to manufacture, building on the infrastructure required to make silicon chips while being more resilient and requiring fewer protective elements.

Moore’s predictions became a self-fulfilling prophecy. The computing power of chips not only did double every 24 months, they had to double every 24 months or the tech industry — and the economy at large — would suffer dire consequences, stifling innovation and economic advancement.

Dean Takahashi at VentureBeat profiles Alex Lidow. Silicon chips have had a decades-long run as the foundation for modern electronics. But a new kind of chip, based on the compound material gallium nitride (GaN), promises to unseat silicon because it has higher performance, less power consumption, and lower cost.

Enhancement-mode gallium nitride (GaN) transistors have been commercially available for over five years. Commercially available GaN FETs are designed to be both higher performance and lower cost than state-of-the-art silicon-based power MOSFETs. This achievement marks the first time in 60 years that any technology rivals silicon both in terms of performance and cost, and signals the ultimate displacement of the venerable, but aging power MOSFET.

Ashlee Vance at Bloomberg Business profiles EPC. Silicon has enjoyed some serious staying power. For going on 60 years, it’s been the semiconductor of choice at the heart of transistors—the tiny switches that power the Information Age. A valley has been named after it. Many billion-dollar empires have been forged from it. And now—look away, silicon—it may finally be on the verge of being replaced.

For the first time in 60 years, a new higher-performance semiconductor technology is less expensive to produce than the silicon counterpart. Gallium nitride (GaN), has demonstrated both a dramatic improvement in transistor performance and the ability to be produced at a lower cost than silicon. GaN transistors have unleashed new applications as a result of their ability to switch higher voltages and higher currents faster than any transistor before. These extraordinary characteristics have ushered in new applications capable of transforming the future. But this is just the beginning.

DesignCon 2015’s Thursday (January 29th) keynote speaker will be Dr. Alex Lidow, CEO and co-founder of Efficient Power Conversion Corporation (EPC). For most of his career, Alex has focused on improving the efficiency of power conversion in hopes of reducing the environmental impact of energy production and consumption. As an R&D engineer at International Rectifier, he co-invented the HEXFET power MOSFET. The patents from this invention brought in more than $900M. Alex holds numerous additional patents in power semiconductor technology, including basic patents in power MOSFETs as well as in GaN FETs. He recently co-authored the first textbook on GaN transistors, “GaN Transistors for Efficient Power Conversion”. You can catch Alex’s keynote speech at DesignCon 2015 on Thursday, January 29, 12:00 PM – 12:30 PM.

Gallium nitride (GaN) is one of the technologies that could well displace silicon MOSFETs in the next generation of power transistors. As silicon approaches its performance limits, GaN devices conduct better and switch faster. In this short podcast, Alex Lidow talks about the differences between GaN and silicon power devices.
