TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The zinc-containing additive comprises zinc oxide. The insulating layer comprises aluminum oxide, titanium oxide, silicon nitride, SiNx:H (where x is not defined), silicon oxide, or silicon oxide/titanium oxide. The insulating layer is a naturally occurring layer.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The paste composition (C1) comprises 0.1-15 wt.% based on solids of the zinc-containing additive. Preferred Components: The surfactant comprises quaternary ammonium compound, coco alkylbis(hydroxyethyl)methyl, ethoxylated methyl sulfate; or alkoxylated ammonium acetate; or an alkoxylated ammonium phosphate and 1,2-ethanediol. The surfactant comprises a substance of formula (I) or (II).X=not defined.    TECHNOLOGY FOCUS - POLYMERS - Preferred Article: In the article (A1), the paste composition has been fired to remove the organic medium and form an electrode having electrical contact with the substrate. Preferred Process: In the process (P1), an insulating layer is present on the first major surface and the paste composition is applied over the insulating layer. In the process (P1), the paste composition is applied onto the first major surface in a preselected pattern. In the process (P1), the firing is carried out in air or an oxygen-containing atmosphere, where the source of electrically conductive metal is finely divided silver particles. Preferred Components: The substrate is a semiconductor substrate. The substrate is a silicon wafer. The substrate comprises an insulating layer present on the first major surface and the paste composition is deposited on the insulating layer. Preferred Definitions:    R1-R4=4-20C alkyl, alkyl/aryl or alkyl/heteroaryl.    At least one of the R1, R2, R3, or R4 comprises a ring containing one or two nitrogen atoms.
