RASIRC Presents Low Temperature ALD of Titanium Nitride at MAM 2017

Company Shows Low Resistivity Results Enabled by Ultra High Purity Hydrazine

San Diego, Calif – March 23, 2017–RASIRC will present at the Materials for Advanced Metallization conference held March 26-29, 2017 in Dresden, Germany. The poster describes an innovative chemistry for low temperature nitride films. Chief Technology Officer Daniel Alvarez will present the poster Low Temperature ALD of Titanium Nitride: Low Resistivity Enabled by Ultra High Purity Hydrazine on Monday March 27 from 13:45 – 15:30.

RASIRC Presents at MAM 2017New device architectures are driving the need for low temperature ALD methods (<400°C) to grow TiNx metal gate electrodes. TiN films require low resistivity and must be ultrathin, continuous, defect free and oxygen free. Hydrazine has very promising thermochemistry for this application but has had several challenges as well. The poster presents a method to overcome these challenges and results that show reduced flammability, reduced water contamination and improved low temperature TiNx film growth on SiON substrate.

“This new TiN metal study shows good feasibility to grow low resistivity TiNitride films at temperatures below 400C. We now have a viable alternative to plasma and high temperature ammonia,” said Jeffrey Spiegelman, RASIRC President and Founder. “This development paves the way for thermal ALD incorporation of ultrathin nitride films in 3D structured devices.”

RASIRC BRUTE® Hydrazine uses a proprietary chemical formulation to deliver ultra-high purity hydrazine from a liquid source that is safer and has quantified low water levels. The company recently released a compact Laboratory version designed for use under vacuum draw. This plug-and-play version enables universities, research institutes and smaller testing environments to work with the chemistry without changing the laboratory tools.
