Kyma and Sinmat Enter Cooperation Agreement to Provide Advanced Crystal Fabrication Services

Kyma Technologies, Inc., a leading supplier of ultra-high purity crystalline gallium nitride (GaN) and aluminum nitride (AlN) materials and related products and services, and Sinmat Inc., a leading provider of innovative chemical mechanical planarization (CMP) technologies for wide band-gap materials, have entered into an agreement to cooperate with each other in the area of advanced crystal fabrication to better serve their customers.

A primary goal of the agreement is to provide customers with a single entry point to access a variety of services which until now have been provided separately by Kyma and Sinmat. Together, the companies hope to provide one-stop shopping and enhanced value to their customers, from boule-grinding, slicing, and orientation-fixing, through to mechanical polishing and CMP. These services are available for a wide variety of materials ranging from silicon carbide, sapphire, gallium nitride, aluminum nitride, and silicon to emerging new materials such as diamond.

“This partnership with Sinmat realizes our final goal towards offering our customers a complete portfolio of crystal fabrication services,” said Tamara Stephenson, Kyma’s Technical Sales Engineer.  “Since we announced the opening of our custom crystal fabrication facility earlier this year, customer interest has been excellent, ranging from simple crystal slicing and shaping to more complex device-wafer backside processing.  Our partnership with Sinmat will allow us to go all the way to making epi-ready crystalline substrates for a range of materials.”

Kyma president and CEO Keith Evans added, “Sinmat’s leading expertise and capabilities in advanced surface modification chemistry and engineering is a perfect complement to Kyma’s leading expertise and capabilities in crystal fabrication processing.  By working together our customers can leverage the strengths of both companies together with the simplicity of a simple and organized customer-supplier interface.”

Sinmat’s Vice-President and CTO Rajiv Singh further elaborated “This agreement provides a unique opportunity for crystal growers to transform their boules into epi-ready wafers utilizing state-of-the-art technologies from both companies.”

Sinmat develops advanced planarization-enabled technologies, manufacturing processes, engineered substrates, and semiconductor devices. Sinmat’s technologies enable higher performance and lower cost manufacturing of semiconductor devices.

The company provides several unique Chemical Mechanical Planarization (CMP) manufacturing technologies needed for current and next-generation semiconductor, clean energy, and advanced material industries, such as:

  • Computer chip and memory devices
  • Power grids
  • LED devices
  • Hybrid electric vehicles

Sinmat’s CMP technologies are based on the company’s unique expertise in creating engineered slurries, mixtures of nano-particles and chemicals that smooth out rough topographies and create defect-free surfaces in a rapid, reliable, and cost-effective manner. Such CMP processes are applied to a wide variety of materials and device systems such as silicon and compound semiconductors, and other advanced materials. Sinmat polishing technologies for wide band-gap materials such as diamond, sapphire, silicon carbide and gallium nitride creates ultra-smooth epi-ready surfaces in a rapid, reliable manner.
