Abstract
Official abstract text for this publication.
A lead-lanthanum-zirconium-titanate (PLZT) capacitor on a substrate formed of glass. The first metallization layer is deposited on a top side of the substrate to form a first electrode. The dielectric layer of PLZT is deposited over the first metallization layer. The second metallization layer deposited over the dielectric layer to form a second electrode. The glass substrate is advantageous as glass is compatible with an annealing process used to form the capacitor.
First claim
Opening claim text (preview).
We claim: 1. A method of forming a capacitor, said method comprising: providing a substrate formed of glass; depositing a first electrode on top of the substrate by electron-beam evaporation; depositing a dielectric layer formed of lead-lanthanum-zirconium-titanate (PLZT) deposited on top of the first electrode using a sol-gel process; and depositing a second electrode on top of the dielectric layer by electron-beam evaporation. 2. The method in accordance with claim 1 , wherein depositing the dielectric layer includes annealing the dielectric layer onto the first electrode and the substrate at six-hundred-fifty degrees Celsius (650° C.). 3. The method in accordance with claim 1 , wherein the method includes rolling the capacitor into a tube-shape, wherein the tube-shape has a radius of less than ten millimeters (10 mm).
