The invention relates to a method for manufacturing a high performance multi layer ceramic capacitor, comprising the steps of: a) providing a substrate having a first edge and a second edge arranged opposite to the first edge, b) depositing a bottom electrode layer onto the substrate using a thick-film and/or thin-film deposition method such that the electrode layer extends all the way from the first edge towards the second edge of the substrate such that a trench free of the bottom electrode layer is provided adjacent in between the deposited bottom electrode layer and the second edge of the substrate, d) depositing a high-k dielectric ceramic layer onto the electrode layer using a thick-film and/or thin-film deposition method such that the high-k dielectric ceramic layer extends all the way to the first edge and to the second edge of the substrate, f) depositing a low-k dielectric layer comprising silicon nitride, silicon dioxide and/or aluminum oxide onto the high-k dielectric ceramic layer using a thin-film deposition method such that the low-k dielectric layer extends all the way to the first edge and to the second edge of the substrate, h) depositing another electrode layer onto the low-k dielectric layer using a thick-film and/or thin-film deposition method such that the another electrode layer extends all the way to the first edge and to the second edge of the substrate, j) etching the capacitor for cutting a trench through the another electrode layer and through the low-k dielectric layer deposited during steps f) and h) such that the trench is arranged distant to second edge of the substrate, m) cutting the capacitor on both edge sides through the extension of the trenches perpendicular to the extension of the substrate, and n) metalizing both cuffed sides of the capacitor by using a thick-film deposition method. |
