Description

Al/M/Al stripes (with M = Hf, Ti or Ti-W) having widths from 0.5 to 200 μm were annealed in N2 and H2 gas. The interdiffusion between layers and hydrogen diffusion in from edges were studied by RBS and nuclear reaction analysis. For Hf and Ti systems, rapid hydrogen diffusion in from the edge was observed. However, this hydrogen did not affect interdiffusion between layers. Al/Hf/Al samples showed an edge-enhanced diffusion, which was likely caused by reactive ion etching (RIE) during processing. For the Ti-W system, the edge diffusion was reduced in H2 during annealing. (orig.)
