Abstract

Surface modification for improved wetting of substrate land pads was done in this research using PECVD. N2 ion source was used and the effect of N+ plasma with varying extractor potentials on the surface properties was examined using topographical AFM analysis, cross-sectional SEM, and EDS analysis. From the AFM surface roughness calculations, as the accelerating voltage is increased, the smoothness of the substrate surface is improved. This supports the theory that higher energy ions provided by higher accelerating voltage results in a higher impact bombardment of surfaces. The flux-supplied solder ball attachment produced generally the same cross-sections with contact angles approximately measuring 75°.
