The Semi Additive Process (SAP) has gained more attraction over the past years because it enables very fine lines and spaces for the production of IC-substrates. When operating with lines and spaces (L/S) of 10/10 μm and less, the copper thickness variation is one of the critical parameters which has to be controlled within a tight range in order to avoid reliability problems in assembly or during the lifetime. This paper contains the results of our investigations on our latest via filling process for IC-substrates with regards to copper thickness variation (WUD), dimple results, filling performance and microsection pictures.
