Title

Study Of Copper Diffusion In Rf Magnetron Sputtered Boron Carbon Nitride Thin Films

Abstract

Secondary-ion-mass spectrometry (SIMS) analysis was conducted to study the copper (Cu) diffusion into boron carbon nitride (BCN) thin films. BCN, being a dense low-k material, has a potential to be the interlayer dielectric in ultralarge scale integration processes. Hence, the diffusion of Cu into the BCN films is a major reliability factor considered in this study. SIMS analysis performed on the BCN films at different annealing temperatures confirmed very low degree of copper diffusion. Copper diffusion increased with an increase in boron concentration of the BCN film.
