SDS 6K
6 kW Microwave Plasma CVD System

Newest system for gem, tool and poly diamond production

• Excellent process stability and repeatability
• Operable in low- to high-power density plasma for accelerated growth rates
• Unique temperature control capabilities at high power densities
• Wide pressure operating range: 10-200 Torr
• Clamshell lid for easy-access substrate placement and chamber cleaning
• Recipe-driven automatic, semiautomatic and manual control

Applications

• Single crystal diamond (gems, tools, electronics) — high quality, high growth rates      (2” diameter)
• Optical grade micro-crystalline diamond — highest quality (2-3” diameter)
• Various grade micro-crystalline diamond — high growth rate  (2-4” diameter)
• Nano and ultra-nano crystalline diamond — (2-4” diameter)

The Seki Diamond SDS 6K Microwave Plasma CVD Diamond System is a high-performance, high-reliability, high-repeatability reactor, one of the most advanced for gem, tool and polydiamond applications. The chamber features a clamshell lid for easy placement of substrates and easy cleaning, and it has an efficient all-copper water-cooled stage.

The system’s stable plasma enables long process durations for thick diamond growth, and its friendly user interface and data-logging features make for easy operation. The 6K provides in-situ monitoring of temperature by IR pyrometer and allows the connection of additional metrology tools including an optical emission spectrometer and interferometer for plasma diagnostics and film thickness monitoring. This system may be used in recipe-driven automatic, semiautomatic or manual mode, and it also offers remote Internet capability. It is field proven for high-volume production operation.

The SDS 6K system is available in multiple configurations. For detailed product information and suggested configurations/options for specific diamond synthesis applications — for research or production — please contact us.

Lab-grown gem diamonds

Creating artisan lab-grown gem diamonds for the jewelry industry is one significant application for Seki Diamond systems. Notably, CVD diamonds produced by our systems can match or exceed the quality and characteristics of natural diamonds — at much lower cost.

In this video you can see diamonds being grown in the lab on a Seki Diamond system at Cardiff University in the UK.
