Patent ID: 8748304

Claim:
A method for making a semiconductor device comprising the steps of: (a) providing a semiconductor substrate, one or more insulating films, and the thick film composition; (b) applying the insulating film to the semiconductor substrate, (c) applying the thick film composition to the insulating film on the semiconductor substrate, and (d) firing the semiconductor, insulating film and thick film composition, wherein the thick film composition comprises: (i) one or more conductive materials; (ii) one or more inorganic binders; and (iii) organic vehicle, wherein 1 to 15 wt % of the inorganic components are submicron particles, characterised in that 1 to 15 wt % of the conductive materials have a d50 of 0.2 to 0.6 microns, and 85 to 99 wt % of the conductive materials have a d50 of 1.5 to 10 microns.
