Abstract
High purity tantalum foils were implanted with 20 keV molecular nitrogen io ns at dose levels varying from 5 x 10(16) to 1 x 10(18) N-2(+) cm(-2). The Fourier Transform Infrared (FTIR) spectra of the implanted layers show the formation of tantalum nitrides of different structures depending on the tot al ion dose. The X-Ray Diffraction (XRD) studies show the formation of Ta2N and TaN0.8 at all doses and TaN at higher doses (5 x 10(17) to 1 x 10(18) N(2)(+)cm(-2)). The FTIR, XRD and electrical studies show sputter limited m aximum nitride concentrations.
