Kyma Technologies, Inc., a leading supplier of advanced semiconductor materials technologies, is pleased to announce its increased capacity for manufacturing AlN templates including diameters ranging from 2 inches up to 150 mm and 200 mm.

Kyma’s AlN templates are manufactured using its patented plasma vapor deposition of nanocolumns (PVDNC™) technology. Manufacturers of blue, green, and white light emitting diodes (LEDs) choose Kyma’s PVDNC™ AlN templates as a replacement for bare and patterned sapphire substrates. Feedback from Kyma’s customers indicates Kyma’s AlN on sapphire templates provide significant improvements in LED brightness, reverse voltage, and electro-static discharge (ESD) yield. Also, Kyma’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 (Si) and sapphire substrates several years ago, most customers have ordered primarily 2 inch and 4 inch diameter products. Recently, Kyma’s customers have shown growing interest in larger diameter AlN template products to drive down device manufacturing costs. In response Kyma has added large diameter PVDNC™ manufacturing capacity, which, together with proprietary enhancements in Kyma’s PVDNC™ process and equipment design, has enabled Kyma to move down the manufacturing cost curve for all of its AlN template products.

Ms. Tamara Stephenson, Kyma’s Director of Sales, notes, “We have listened to our customers and have responded to their needs. 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 150 mm and 200 mm.”
