Abstract:
A method of manufacturing a capacitor of a semiconductor device, comprising:forming a metal or metal oxide electrode over a semiconductor substrate;forming a Ta.sub.2 O.sub.5 film on the metal or metal oxide electrode;heat-treating the Ta.sub.2 O.sub.5 film at a temperature lower than a crystallizing temperature of the Ta.sub.2 O.sub.5 film to compensate for oxygen deficiencies and remove impurities; andheat-treating the Ta.sub.2 O.sub.5 film having been subjected to said heat-treating at the temperature lower than the crystallizing temperature of the Ta.sub.2 O.sub.5 film at a temperature higher than or equal to the crystallizing temperature of the Ta.sub.2 O.sub.5 film after said heat-treating step to crystallize the Ta.sub.2 O.sub.5 film.
