Abstract:
1. A method of fabricating a capacitor, comprising: (a) providing a non-copper metal substrate that has first and second surfaces, wherein the non-copper metal substrate has a thickness in the range between about 40 microns and 120 microns; (b) annealing the non-copper metal substrate; (c) polishing the first surface of the non-copper metal substrate; (d) coating the first surface of the non-copper metal substrate with a buffer layer; (e) depositing a dielectric material on the first surface of the non-copper metal substrate to form a dielectric layer thereon, wherein the depositing the dielectric material is formed after the annealing the non-copper metal substrate, the polishing the first surface of the non-copper metal substrate, and the coating the first surface of the non-copper metal substrate with the buffer layer; (f) depositing a first conductive material on the dielectric layer to form an electrode thereon; (g) removing non-copper metal from the second surface of the non-copper metal substrate to reduce the thickness of the non-copper metal substrate; and (h) depositing a second conductive material on the whole of the second surface of the non-copper metal substrate to form an electrode thereon.
