Beschreibung
Zusammenfassung:	The surface of metallic features are coated with a desensitizer composition comprising an amino-silane to reduce the likelihood of chemical interaction between the metallic feature and a photosensitive functional group that is included in a dielectric composition that is coated over the metallic features. The chemical interaction adversely affects the photosensitivity of the dielectric composition and, thus, inhibits the formation of complete and well defined via interconnections through the dielectric composition.
