Patent ID: 8652873

Claim:
A process comprising: (a) providing an article comprising one or more insulating films disposed onto at least one surface of a semiconductor substrate; (b)(e) applying a thick-film paste composition onto the one or more insulating films to form a layered structure, the thick-film paste composition comprising: i) 80-99.5 wt % of a source of electrically conductive metal; ii) 0.5 to 20 wt % of a lead-vanadium-based oxide; and iii) an organic medium, wherein the source of electrically conductive metal and the lead-vanadium-based oxide are dispersed in the organic medium and wherein the above wt % are based on the total weight of the source of electrically conductive metal and the lead-vanadium-based oxide, the lead-vanadium-based oxide comprising 52-80 wt % PbO, 10-45 wt % V 2 O 5 and one or more additional oxides with a liquidus temperature of 900° C. or less, said one or more additional oxides comprising at least one oxide selected from the group consisting of 4-18 wt % Bi 2 O 3 , 0.5-8 wt % 1-3 wt % and 0.5-6 wt % TeO 2 , wherein said oxide wt % are based on the total weight of the lead-vanadium-based oxide; and (c) firing the semiconductor substrate, the one or more insulating films, and the thick-film paste wherein the organic medium of the thick film paste is volatilized, thereby forming an electrode in contact with the one or more insulating layers and in electrical contact with the semiconductor substrate.
