Title: Ceramic-wound-capacitor with lead lanthanum zirconium titanate dielectric

Abstract

A ceramic-wound-capacitor includes a first-electrically-conductive-layer, a dielectric-layer, a second-electrically-conductive-layer, and a protective-coating. The dielectric-layer is formed of lead-lanthanum-zirconium-titanate (PLZT). The protective-coating has a thickness of less than ten micrometers (10 μm) and provides electrical isolation between the first-electrically-conductive-layer and the second-electrically-conductive-layer of the ceramic-wound-capacitor. A method for fabricating the ceramic-wound-capacitor includes the steps of feeding a carrier-strip, depositing a sacrificial layer, depositing a first-electrically-conductive-layer, depositing a dielectric-layer, and depositing a second-electrically-conductive-layer to form an arrangement coupled to the carrier-strip by the sacrificial-layer, separating the arrangement from the carrier-strip and sacrificial-layer, creating an exposed-surface of the first-electrically-conductive-layer, applying a protective-coating to the exposed-surface of the first-electrically-conductive-layer, winding the arrangement with the protective-coating to form a ceramic-wound-capacitor, where the protective-coating is in direct contact with the first-electrically-conductive-layer and the second-electrically-conductive-layer of the ceramic-wound-capacitor.

Wound/stacked ceramic film capacitors, method for making ceramic film capacitors

Patent Ma, Beihai; Balachandran, Uthamalingam; Dorris, Stephen E.; ...

The invention provides a process for making ceramic film capacitors, the process comprising supplying a flexible substrate, depositing a first electrode on a first region of the flexible substrate, wherein the first electrode defines a first thickness, overlaying the first electrode with a dielectric film; and depositing a second electrode on the ceramic film, wherein the second electrode defines a second thickness. Also provided is a capacitor comprising flexible substrate, a first electrode deposited on said flexible substrate, a dielectric overlaying the first electrode; and a second electrode deposited on said dielectric.

Method of making dielectric capacitors with increased dielectric breakdown strength

Patent Ma, Beihai; Balachandran, Uthamalingam; Liu, Shanshan

The invention is directed to a process for making a dielectric ceramic film capacitor and the ceramic dielectric laminated capacitor formed therefrom, the dielectric ceramic film capacitors having increased dielectric breakdown strength. The invention increases breakdown strength by embedding a conductive oxide layer between electrode layers within the dielectric layer of the capacitors. The conductive oxide layer redistributes and dissipates charge, thus mitigating charge concentration and micro fractures formed within the dielectric by electric fields.

PLZT capacitor and method to increase the dielectric constant

Patent Taylor, Ralph S.; Fairchild, Manuel Ray; Balachjandran, Uthamalingam; ...

A ceramic-capacitor includes a first electrically-conductive-layer, a second electrically-conductive-layer arranged proximate to the first electrically-conductive-layer, and a dielectric-layer interposed between the first electrically-conductive-layer and the second electrically-conductive-layer. The dielectric-layer 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 (10 kHz). A method for increasing a dielectric constant of the lead-lanthanum-zirconium-titanate material (PLZT) includes the steps of depositing PLZT to form a dielectric-layer of a ceramic-capacitor, and heating the ceramic-capacitor to a temperature not greatermore » than 300.degree.

Nanostructure multilayer dielectric materials for capacitors and insulators

Patent Barbee, Jr., Troy W. (Palo Alto, CA); Johnson, Gary W [Livermore, CA]

A capacitor is formed of at least two metal conductors having a multilayer dielectric and opposite dielectric-conductor interface layers in between. The multilayer dielectric includes many alternating layers of amorphous zirconium oxide (ZrO.sub.2) and alumina (Al.sub.2 O.sub.3). The dielectric-conductor interface layers are engineered for increased voltage breakdown and extended service life. The local interfacial work function is increased to reduce charge injection and thus increase breakdown voltage. Proper material choices can prevent electrochemical reactions and diffusion between the conductor and dielectric. Physical vapor deposition is used to deposit the zirconium oxide (ZrO.sub.2) and alumina (Al.sub.2 O.sub.3) in alternating layers tomore » form a nano-laminate. « less
