The outstanding smoothness of ADT's UNCD products with surface roughness of the order of 10 nanometers is well known, and their new UNCD Horizon product level has reached a new level - surface roughness up to 1 nanometer. Such smooth diamond materials can be combined with other materials and have achieved breakthrough applications in RF, MEMS, nanoimprint lithography, diamond nanophotonics, biosensors, and biomedical devices. On the other hand, this product can also directly connect the diamond heat sink to the transistor, thus solving one of the most headaches in the semiconductor industry. In addition, it allows for epitaxial silicon deposition directly on the diamond material.
In order to achieve the ultra-high finish of UNCD Horizon, ADT applied a standard semiconductor processing technology, chemical mechanical polishing, and used it in the processing of UNCD series materials. "Chemical mechanical polishing opens up huge possibilities for the development of diamond devices using wafer-scale processing technology," commented John Carlisle, chief technology officer of ADT. As the hardest material in the world. It is extremely difficult to achieve flattening of diamonds. ADT's UNCD platters have been very smooth, and they have applied chemical mechanical polishing techniques to achieve ultra-high flatness.
UNCD Horizon enables potential applications for surface acoustic wave devices in the integrated movement of diamond and highly optimized aluminum nitride piezoelectric films. The device combines low insertion loss, higher operating frequency, and direct integration with CMOS driver circuitry to improve overall performance. Flatness is critical to reducing energy consumption. In this regard, Dan Stevens, chief technology officer of Vectron International, said: "The ability to produce such ultra-smooth surface diamonds will likely lead to many new applications for diamonds in the field of RF electronics, especially for filter devices operating in the Gyrtz frequency range. â€
Columbia University is using UNCD Horizon in nanoimprint lithography to print nanoscale patterns with resolutions above 10 nanometers on substrates that are used in the manufacture of biological flow cells and semiconductors. Because UNCD Horizon achieves excellent mechanical properties, low adhesion, and good biocompatibility within a few nanometers of feature size, it is particularly well-suited for use in nanoimprint dies. Mark Schvartzman of Columbia University's Nanotechnology Center believes that "the extremely low surface roughness of UNCD Horizon materials meets our needs in the manufacture of nanoimprint stencils that can withstand high pressures and mechanical forces."
Through the use of UNCD Horizon, researchers at Harvard University are developing diamond nanophotonics for use in biochemical sensing, optical information processing, and nanomachinery. "I believe that the diamond nanophotonics technology we are currently developing will play an important role in quantum information processing and remote sensing applications," said Dr. Marko Loncar, Principal Investigator, Harvard University's Nano-Optics Laboratory.
UNCD Horizon has been used to study the feasibility of using nano-imprint lithography hard masks using focused ion beam technology. The use of diamond as a hard mask material eliminates the key issue of adhesion in imprint lithography, and focused ion beam technology increases flexibility and simplifies the mask manufacturing process. Dr. Warren McKenzie from the University of New South Wales presented a diamond hard mask with the ADT logo (shown below), which was published in the July 2009 issue of Microscopy and Microanalysis.
ADT's UNCD materials meet particle count, disk deflection and cleanliness requirements, can be patterned using reactive ion etching, and can be integrated into complex films of heterostructures. It allows the diamond to be used to make an integrated film or sacrificial layer. Diamond has long been highly regarded as an engineering material. Now, UNCD Horizon allows diamonds to be integrated into MEMS and semiconductor manufacturing.
American ADT Company Launches World's Smoothest Diamond Products
On October 6, 2009, ADT Corporation of the United States announced the launch of the world's smoothest vapor deposited diamond product, UNCD Horizon. This product represents a new generation of diamond wafer technology. The surface roughness level of this diamond film is comparable to that of electronic grade silicon wafers, opening up new prospects for diamond applications in a variety of electronic and biomedical devices.
