UNCD Wafers:
A Family of Materials
UNCD is ADT's brand name for a family of thin film diamond products.
UNCD
Aqua The Aqua series of UNCD®
films from ADT are electrically insulating phase-pure nanocrystalline
diamond films. Other nanocrystalline diamond films are typically
comprised of graphitically-bonded material intermixed with crystalline
diamond grains.In contrast, UNCD films have no amorphous graphitic
phases.The results are films that capture the hardness, modulus
and other extreme properties of natural diamond but are also smooth
and have very low internal stresses.
- Aqua Series (electrically insulating diamond)
- Aqua 25 - Thin, smooth (~7 nm rms) UNCD film. Perfect
for MEMS devices, smooth nanotechnology application like
nano imprint lithography and in- general, the all-purpose
UNCD product
- Aqua 50 - The best tribological UNCD for industrial low-friction
coatings
- Aqua 100 - The highest thermal conductivity UNCD, appropriate
for heat spreading and transparency in the optical spectrum
- To determine which Aqua product is best for your application,
see the table in the UNCD
Wafer brochure.

UNCD Lightning™:
The Lightning series of UNCD films from ADT are electrically-conductive
versions of the Aqua series. UNCD Lightning has a resistivity
of approximately 0.1 ohm-cm. For more information about UNCD Lightning,
please contact us directly.

NEW! UNCD Horizon™:
The Horizon technology delivers UNCD in ultra-smooth form. The
surface of a Horizon 25 wafer has a roughness value of less than
1nm rms. More information can be found on the press
release and the Horizon
brochure.
UNCD Wafers
UNCD Wafers are wafer-scale diamond products, used for
MEMS development, tribological testing, and unique nano-scale
processing applications. UNCD Wafers offer the ability to create
and experiment with the extraordinary properties of diamond, using
the award winning family of UNCD materials. UNCD Wafers meet a
set of baseline wafer-level specifications for thickness/ property
uniformity, wafer bow, and particle counts suitable for direct
insertion into a MEMS foundry process sequence.

DoSi™ Wafers (diamond
on silicon): A prime silicon wafer with a thin film of UNCD. UNCD
DoSi Wafers are offered for all of the family of UNCD materials.
Wafer sizes available are 100, 150, 200, and 300mm sizes.

DOI™ Wafers (diamond
on insulator): Standard silicon wafers coated with a thermal SiO2
layer (nominal 1 micron thickness) followed by UNCD Aqua 25, 50,
or 100. These substrates are ready for further MEMS processing
using standard surface micromachining techniques to make UNCD-based
cantilevers, resonators, diaphragms, windows, etc. UNCD DOI Wafers
are offered for all of the family of UNCD materials. Wafer sizes
available are 100, 150, 200, and 300mm sizes.

UNCD Diamond Windows: For
a limited time, ADT is offering die of small 300 micron square
diamond windows for purchase. The wafer die is 1.5 cm2, with UNCD
Aqua 25 windows in an array of 2 mm2.
Custom UNCD Wafers: ADT is
happy to work with its customers to develop custom wafer stacks
suitable for creating complex MEMS devices. ADT will also integrate
UNCD into a customer's patterned wafer stack. Please contact
us for pricing and availability.

Custom MEMS Development:
ADT is happy to work with its customers to develop a variety of
custom MEMS diamond products. An example of a project might be
similar to the left image. This is an array of diamond pyramids,
a few microns in height. If you are interested in creating your
MEMS product with diamond, contact us.
