THE METHOD OF FABRICATING A HIGH CAPACITANCE DEVICE ON A SUBSTRATE WHICH COMPRISE THE STEPS OF: DEPOSITING A FIRST ELECTRODE MATERIAL ON SAID SUBSTRATE AND FORMING A FIRST CAPACITOR ELECTRODE; MIXING BARIUM TITANATE WITH A MATERIAL SELECTED FROM THE GROUP CONSISTING OF STRONTIUM TITANATE, LEAD TITANATE AND LEAD ZIRCONATE IN A FIRST GIVEN RATIO AND SINTERING SAME TOGETHER TO FORM A FIRST FERROELECTRIC MATERIAL; MIXING BARIUM TITANATE WITH A MATERIAL SELECTED FROM THE GROUP CONSISTING OF STRONTIUM TITANATE, LEAD TITANATE AND LEAD ZIRCONATE IN A SECOND GIVEN RATIO DIFFERENT FROM SAID FIRST GIVEN RATIO AND SINTERING SAME TOGETHER TO FORM A SECOND FERROELECTRIC MATERIAL; GRINDING SAID FIRST FERROELECTRIC MATERIAL AND SAID SECOND FERROELECTRIC MATERIAL TOGETHER IN A GIVEN PROPORTION; ADDING GLASS BINDER MATERIAL TO SAID FERROELECTRIC MATERIAL MIXTURE TO FORM A RESULTANT MIXTURE THEREOF, SAID BINDER MATERIAL CONSTITUTING AT LEAST 15%, BY VOLUME, OF SAID RESULTANT MIXTURE, DEPOSITING SAID RESULTANT MIXTURE OVER SAID FIRST CAPACITOR ELECTRODE; FIRING SAID RESULTANT MIXTURE ABOVE THE MELTING POINT OF SAID GLASS BINDER MATERIAL BUT BELOW THE SINTERING TEMPERATURE OF SAID FERROELECTRIC MATERIALS; AND DEPOSITING A SECOND ELECTRODE MATERIAL ON SAID FINAL RESULTANT MIXTURE AND FORMING A SECOND CAPACITOR ELECTRODE.
