Kyma Commissions K200™ HVPE Growth Tool

Kyma Technologies, Inc., a leading developer of advanced wide bandgap semiconductor materials technologies, is pleased to announce it has commissioned its K200™ hydride vapor phase epitaxy (HVPE) growth tool.

Kyma's newly constructed K200™ HVPE tool represents a first for the industry and was designed by Kyma engineers to enable uniform and rapid growth of high quality GaN on a number of different substrates. HVPE has several advantages over metalorganic chemical vapor deposition (MOCVD) including faster growth rates, lower cost starting materials, and a higher purity growth environment aided by the use of elemental group III sources instead of carbon containing metalorganic sources. As a result, HVPE enables better GaN to be grown more rapidly and at lower cost.

The design of the K200™ HVPE tool leverages over a decade of experience at Kyma in designing tools and developing processes for the application of hydride vapor phase epitaxy (HVPE) growth technology to crystalline wide bandgap semiconductor materials including GaN, AlN, AlGaN, and Ga2O3.

The K200™ HVPE tool has the following standard features & capabilities and available options:

  • Standard Features & Capabilities
    • Fully Automated 25 x 200-mm Wafer Carousel Loadlock & Transfer System
    • Designed by Kyma and Brought to Market by a World Class III-N OEM
    • System Leverages Over a Decade of Kyma Process Experience
    • High Uniformity 1x200-mm Diameter Wafer Growth
    • Long Uptime & Fast Maintenance Cycles
    • Growth Rates of 10 – 200μm/hr
    • Standard Design is for GaN Growth
  • Options
    • Base Materials: AlN, AlGaN, Ga2O3, & (Al,Ga)2O3
    • Dopants: Si, Fe, Mg, and Other Dopants
    • Wafer diameter: 150-mm (other configurations possible)

Today's announcement represents a major milestone for Kyma and sets the stage for Kyma to begin testing the materials growth capabilities of its K200™ HVPE tool.
