PLZT CAPACITOR AND METHOD TO INCREASE THE DIELECTRIC CONSTANT

TAYLOR RALPH S / FAIRCHILD MANUEL RAY / BALACHANDRAN UTHAMALINGAM / LEE TAE H

A ceramic-capacitor (10) includes a first electrically-conductive-layer (14), a second electrically-conductive-layer (18) arranged proximate to the first electrically-conductive-layer (14), and a dielectric-layer (16) interposed between the first electrically-conductive-layer (14) and the second electrically-conductive-layer (18). The dielectric-layer (16) is formed of a lead-lanthanum-zirconium-titanate material (PLZT), wherein the PLZT is characterized by a dielectric-constant greater than 125, when measured at 25 degrees Celsius and zero Volts bias, and an excitation frequency of ten-thousand Hertz (10kHz). A method (20) for increasing a dielectric constant of the lead-lanthanum-zirconium-titanate material (PLZT) includes the steps of depositing PLZT to form a dielectric-layer (16) of a ceramic-capacitor (10), and heating the ceramic-capacitor (10) to a temperature not greater than 300° C.
