Kyma increases AlN template manufacturing capacity

Kyma Technologies Inc of Raleigh, NC, USA (which provides crystalline nitride materials, crystal growth and fabrication equipment, and power switching electronics) has increased its capacity for manufacturing aluminium nitride (AlN) templates, including diameters ranging from 2 inches up to 150mm and 200mm.

Kyma manufactures AlN templates using its patented plasma vapor deposition of nanocolumns (PVDNC) technology. The firm says that manufacturers of blue, green and white light-emitting diodes (LEDs) are choosing its PVDNC AlN templates as a replacement for bare sapphire substrates and patterned sapphire substrates (PSS). Feedback from customers indicates that Kyma's AlN-on-sapphire templates provide significant improvements in LED brightness, reverse voltage, and electro-static discharge (ESD) yield. Also, the firm's AlN-on-silicon (Si) templates have been demonstrated to support high-performance GaN transistor manufacturing for both RF and power switching applications.

While Kyma demonstrated large-diameter AlN on both silicon and sapphire substrates several years ago, most customers have ordered primarily 2-inch and 4-inch diameter products. Recently however, to drive down device manufacturing costs, customers have shown growing interest in larger-diameter AlN template products. In response, Kyma has added large-diameter PVDNC manufacturing capacity which, together with proprietary enhancements in its PVDNC process and equipment design, has enabled Kyma to move down the manufacturing cost curve for all of its AlN template products. 

"We have listened to our customers and have responded to their needs," notes Kyma's director of sales Ms Tamara Stephenson. "We are excited to be able to offer more aggressive pricing as well as increased volume availability of all of our AlN template products, including larger-diameter products including 150mm and 200mm."
