sp3 Diamond Technologies,
Inc. (sp3), a leading supplier of diamond film products, equipment and services,
today brought to market the newest member of its Model 650 Series of Hot Filament
CVD (chemical vapor deposition) Diamond Coating Systems with the Model 655D
for doped diamond applications. The Model 655D incorporates advanced process
capabilities to dope diamond as it is deposited, making it electrically conductive
with resistivity from .05 to 10 ohm-cm, while maintaining excellent uniformity.
The Model 655D has been configured with two dopant flow ranges giving the user
flexibility to tailor processes with very specific electrical characteristics.
By adding gas loops to the baseline diamond deposition configuration, the 655D
has the ability to deliver Boron dopant via a Hydrogen carrier gas. Boron is
required to dope diamond films in order to render them electrically conductive.
The Model 655D also integrates new system controls and a dedicated user interface
to assure process repeatability and intrinsically safe operation.
“Over the past 15 years, sp3 has gained a deep understanding of the potential
applications for diamond based on extensive customer experience and in-house
R&D activities,” said Dwain Aidala, president and COO for sp3 Diamond
Technologies. “In the Model 655D, and the entire Model 650 Series, sp3
is bringing its industry leadership in diamond deposition to market in the form
of turnkey systems that are fully configured and ready-for-use for specific
sp3’s hot filament diamond deposition technology offers customers a critical
advantage in terms of reduced development time and shortened time-to-market.
By incorporating electrically conductive diamond into its reactor’s broad
range of commercial applications, which includes cutting tools, wear surfaces
and wafer-scale diamond, sp3 is expanding future customers’ opportunities
to implement thin film diamond in conductive diamond applications, such as in
coated electrodes for water treatment and electrochemistry. Having been developed
originally for internal use, the company has deployed over twenty hot filament
CVD diamond coating systems around the world.
