Abstract:
A process for forming a capacitor is presented. The process includes providing a laminate including a dielectric layer disposed on a sacrificial substrate, forming a free-standing metallized dielectric layer and packaging the free-standing metallized dielectric layer to form a capacitor. The dielectric layer includes a polyetherimide. The step of forming the free-standing metallized dielectric layer is performed by: (a) disposing a metal layer on the dielectric layer to form a metalized laminate such that a metalized dielectric layer is formed on the sacrificial substrate, and removing the sacrificial substrate to form the free-standing metallized dielectric layer; or (b) removing the sacrificial substrate from the laminate to form a free-standing dielectric layer, and disposing a metal layer on the free-standing dielectric layer to form the free-standing metallized dielectric layer. A capacitor formed by the process is presented. A process for forming a capacitor by a roll-to-roll processing technique is also presented.
