In 3D printers, these diamond-coated parts can remove material more precisely, creating detailed objects with finer spatial resolution. Tiny diamond-coated drill bits can be used in precision applications from dental implants to drilling holes in circuit boards. This technology is especially useful in applications that require intricate machining. The coating technology was patented by Sumant and licensed by Intel. This technology is now being used by NCD Technologies, a company Heaney started to produce NCD-coated micro-drills. The thin layers of diamond protect and strengthen micro-size cutting tools, extending their working lifespan while preserving their precise geometry. This technique uses hot filaments to deposit coatings of diamond a few tenths of a millimeter thick. Sumant originally developed the technology at the University of Wisconsin-Madison with Patrick Heaney, a former student there. The second award is for a nanocrystalline diamond coating for micro-tools. AKHAN now uses Sumant’s deposition technique in their manufacturing processes, and intends to expand its use to all its low-temperature diamond processes and an additional range of products through a joint agreement between AKHAN and Argonne. Sumant’s partnership with AKHAN was forged when Adam Khan, founder and CEO of the company, approached Sumant after a conference talk. The Miraj Diamond™ platform resulted from the marriage of two scientific breakthroughs: the ability to deposit nanocrystalline diamond films at relatively low temperatures and a doping process that makes NCD into a good semiconducting material. “With these attributes, diamond films have the potential to revolutionize the semiconductor industry,” said Sumant. Diamond films can also be used in power devices, because diamond can carry a high amount of current. Diamond has five times the thermal conductivity of copper, which allows it to act as a heat sink and shuttle heat away from electronic components. Thanks to diamond’s many useful properties, the Miraj Diamond™ process may have wide applications in electronics. AKHAN has created a new technique that makes the doping process much more efficient. The gas is ignited and forms small diamonds that grow on a wafer, producing a continuous thin layer.Īlthough diamond is ordinarily an excellent insulator, it can be altered in a process called “doping” to become a semiconductor, an important component in many different electronic systems. This technique requires only an activation medium like plasma, argon gas and a carbon source, such as methane. ![]() Rather than create diamond films with traditional methods that require extraordinarily high temperatures and pressures, the technique developed at Argonne can deposit a thin diamond film at relatively low temperatures of around 400 degrees Celsius. These technologies together will allow manufacturers to create better integrated circuits for telecommunications, defense and aviation electronics. Sumant and his colleagues developed the low-temperature NCD deposition technology at Argonne’s Center for Nanoscale Materials, while the doping technique was developed at AKHAN Technologies, an industry partner based in Illinois. In 3D printers, these diamond-coated parts can remove material more precisely, creating detailed objects with finer spatial resolution.Īrgonne’s NCD technologies rely on incredibly small diamonds and can be used for mechanical, biological, optical, electronic and electrochemical applications.
