Kyma Demonstrates 10-Inch Diameter Aluminum Nitride on Sapphire Template Product

Kyma Technologies, a supplier of crystalline aluminum nitride and gallium nitride materials and related products and services, has announced the successful demonstration of a 10-inch diameter aluminum nitride on sapphire template.

 

Kyma’s AlN templates are manufactured using its patented plasma vapor deposition of nanocolumns  technology, which provides GaN LED manufacturers with throughput, cost, and performance benefits. Light emitting diode manufacturers choose Kyma’s PVDNC AlN templates as a replacement for bare and patterned sapphire substrates by manufacturers of blue, green, and white light emitting diodes (LEDs).

 

The 250-mm (10-inch) diameter sapphire substrate was provided courtesy of Monocrystal, of Stavropol, Russia.

 

Until recently, the wafer diameter standard for GaN LED wafer manufacturing has been 50mm (2”). Recently, sapphire manufacturers have made much progress in increasing the size of sapphire boules from which ever larger sapphire substrates can be sliced, with sapphire diameter demonstrations up to 12” being achieved by certain sapphire providers. This has enabled some of the major GaN LED manufacturers to begin transitioning to larger diameter sapphire, up to 150-mm (6-inch) in some cases, to enhance manufacturing throughput and to achieve better economies of scale. While 10-inch sapphire based AlN templates are simply a demonstration today, Kyma believes the LED community will begin looking beyond 150mm (6-inch) diameter in the next few years.

 

In February 2011 Kyma announced the successful commissioning of its new high volume PVDNC AlN template manufacturing tool and the demonstration of the world’s first 300mm (12-inch) diameter AlN on silicon template that is suitable for high quality gallium nitride growth. In November 2011, Kyma announced successful customer qualification of products manufactured on that same tool.

 

“Over the past year we have demonstrated several firsts in AlN template manufacturing, in each case leveraging Kyma’s new volume manufacturing tool, including customer qualification of our 2” sapphire based product and large diameter demonstrations on both silicon and sapphire,” said Ed Preble, Kyma’s Chief Technology Officer. “Together these results confirm the diameter scalability of the PVDNC AlN process as well as its robustness and flexibility for growth on different starting substrates.”
Connecting the Compound Semiconductor Industry

The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.

Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
