Kyma Expands Its Aluminum Nitride Template Manufacturing Capacity

Kyma Technologies, Inc., a leading supplier of crystalline aluminum nitride (AlN) and gallium nitride (GaN) materials and related products and services, is pleased to announce expansion of its AlN template manufacturing capacity for both sapphire and silicon based AlN template products.

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

The expansion of Kyma’s AlN PVDNC™ template manufacturing capacity is based on successful customer qualification of products fabricated in its newest high volume PVDNC™ reactor, the commissioning of which was announced by the company earlier this year.

LED customer feedback indicates significant improvements in LED brightness, reverse voltage, and electro-static discharge (ESD) yield. Similar benefits have been previously verified using Kyma’s lower volume manufacturing tools which the company has used since it was founded in 1998.

Kyma has also qualified the tool for production of PVDNC™ AlN on silicon wafers. Several customers report improved device properties for both RF and power switching applications.

Qualification of this new tool was not a small task. Its design is totally new compared to earlier designs, with key design changes targeting improved tool uptime, shorter process cycle time, and better process repeatability and uniformity.

“We are pleased to qualify our new reactor for both sapphire and silicon based PVDNC™ AlN template products,” said Heather Splawn, Kyma’s Chief Operating Officer. “Doing so represents not only a significant boost to our manufacturing capacity; it also validates our improved tool design approach which should prove beneficial for our continued expansion plans going forward.”
