Kyma's AlN Template Production Ramps Up

The firm says over the past two weeks many customers in multiple nations have said that Kyma has by far the best aluminium nitride templates on the market


Kyma Technologies has provided an update on its AlN template manufacturing capability.

The company is a domestic supplier of crystalline GaN and AlN template materials, as well as bulk GaN substrates.

Most of these products are fabricated beginning using Kyma’s patent protected plasma vapour deposition of nanocolumns (PVDNC) crystal growth process which is implemented on Kyma’s patented and proprietary PVDNC crystal growth tools.

The AlN templates are produced both for commercial sale and for use internally for fabricating GaN templates, bulk GaN substrates, and related products.

Until 2011 Kyma’s PVDNC effort relied on early-generation PVDNC crystal growth tools which were especially useful for the company’s R&D stage but were not designed for high volumes. To keep up with growing demand for Kyma’s AlN and GaN products and the growing interest in larger diameter products, in 2011 Kyma designed and built their first PVDNC production tool which featured a larger diameter platter and much faster growth cycle time.

Related company announcements made in 2011 and 2012 include those of 1) the expansion of AlN template manufacturing capacity, 2) the demonstration of a 12" AlN on silicon template, and 3) the demonstration of a 10" AlN on sapphire template.

Primary applications for Kyma’s AlN templates are for visible LEDs and power switching electronics. Recently demand has also grown for ultra-violet (UV) LED applications. Customers are interested in both AlN on sapphire and AlN on silicon for the LED applications; power electronics customers are focused mostly on AlN on silicon.

Ed Preble, Kyma’s Chief Marketing Officer, and Tamara Stephenson, Kyma’s Technical Sales Engineer, just completed a sales and marketing trip in the Asian Pacific focusing on application of Kyma’s materials for LED applications.

Preble notes, “Over the past two weeks we were told by multiple customers in multiple nations that we have by far the best AlN templates on the market. Such customer input validates our PVDNC process as the technology of choice for creating a high quality nucleation surface for our customers’ device wafer epitaxy processes."



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
