Kyma developed this product in collaboration with a partner as part of an advanced mid UV LED technology research project, which is ongoing. However, AlGaN Templates have great potential to impact other applications too, including high power RF communications and high power switching electronics.


Kyma’s initial AlGaN Template product offering consists of a 5-micron thick epi-ready Al0.9Ga0.1N buffer layers grown on top of a 2” diameter sapphire substrate. Additional compositions and thicknesses will be offered in the future.


“Transistors based on AlN/AlGaN heterostructures have already been demonstrated which outperform their GaN counterparts in high temperature operation that is required for uncooled automotive applications,” stated Ed Preble, Kyma’s Chief Technology Officer. “Our AlGaN templates should support a further boost in transistor performance since they support lower defect density active regions when compared to typical MOCVD or MBE buffer layers grown on SiC or sapphire substrates.”


Keith Evans, Kyma’s president & CEO, added, “Our engineers have accomplished a lot very quickly and have already demonstrated high Al-content crack-free AlGaN layers over 10 microns thick. And we aren’t stopping there. Our goal is to get up to 100 microns within the next six months and to demonstrate free-standing AlGaN in 2012.”


In the future, the company plans to expand their AlGaN Template product offering to other combinations of Al-content, AlGaN thickness, substrate diameter (e.g., 3” and 4”), and substrate composition (e.g., silicon and SiC).


Skyworks to acquire power management guru Advanced Analogic Tech


The firm is expanding its portfolio with Advanced Analogic’s cutting edge analogue products and accelerates Skyworks’ entry into adjacent vertical markets.


Skyworks Solutions, an innovator of high reliability analogue and mixed signal semiconductors


enabling a broad range of end markets, has signed a definitive agreement to purchase Advanced Analogic Technologies Incorporated.


Advanced Analogic is a semiconductor company focused on enabling energy-efficient devices for consumer electronics, computing and communications markets. This acquisition expands Skyworks’ portfolio with highly complementary analogue semiconductor products including battery chargers, DC/DC converters, voltage regulators and LED drivers. The analogue power management market is expected to grow to $12.1 billion in 2014, up from $9.9 billion in 2010 according to Gartner market research.


“Skyworks’ acquisition of Advanced Analogic Technologies will enable us to further capitalise on our strong smart phone, tablet, set-top box and infrastructure positions with an expanded and differentiated product portfolio while accelerating our entry into new vertical markets,” said David J. Aldrich, president and chief executive officer of Skyworks.


“At a higher level, analogue power management semiconductors represent a strategic growth market for Skyworks as our customers increasingly demand both ubiquitous wireless connectivity and power optimization across seemingly every kind of electronic platform. With Advanced Analogic Technologies, Skyworks will be well positioned to address these massive twin market opportunities leveraging our broad customer relationships, innovative product portfolios and increasing operational scale,” he continued.


“The Advanced Analogic Technologies team is excited to be joining forces with Skyworks given their leadership market positions coupled with scale advantages,” said Richard K. Williams, president, chief executive officer and chief technical officer of Advanced Analogic Technologies. “Both companies share a common vision of the enormity and growth potential of the analogue semiconductor market. Together, we can better address our customers’ demand for highly integrated power management solutions across a broader range of markets and applications. We believe this transaction will benefit our customers, employees and, most importantly, our shareholders.”
