Patent ID: 8654503

Claim:
A method of forming a capacitor, comprising: forming a first metal layer on a surface of a first dielectric layer having a moisture vapor transmission rate of less than about 0.25 gram/m 2 ·day, the first metal layer extending along a length and a width of the first dielectric layer but terminating prior to a first edge of first and second edges of the first dielectric layer that define the width of the first dielectric layer; forming a second metal layer on a surface of a second dielectric layer having a moisture vapor transmission rate of less than about 0.25 gram/m 2 ·day, the second metal layer extending along a length and a width of the second dielectric layer but terminating prior to a first edge of first and second edges of the second dielectric layer that define the width of the second dielectric layer; placing the first dielectric layer on top of the second metal layer with the first edge of the first dielectric layer disposed adjacent the second edge of the second dielectric layer to form a layered structure; and rolling the layered structure about itself to form the capacitor.
