Claims16
A method of manufacturing 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:
- (a) one or more conductive materials;
- (b) one or more inorganic binders;
- and
- (c) organic vehicle,
- wherein 1 to 15% of the conductive materials are submicron particles.
