Abstract: The invention relates to a conductive paste, comprising from 50 to 97 wt % of electrically conductive particles, 3 to 50 wt % of an organic medium and 0 to 20 wt % of a glass frit, the organic medium comprising a solvent, wherein the organic medium additionally comprises 10 to 90 wt % of a hydrocarbon-based lubricating oil and 2 to 60 wt % of a polymeric component, each based on the total amount of the organic medium, the polymeric component having a solubility of at least 100 g/kg in the lubricating oil. The invention further relates to a semiconductor device comprising a semiconductor substrate with at least one surface onto which an electrically conductive pattern is printed by using the paste.
