A method of forming successive metal layers of varying widths on a substrate is disclosed. A mask having a through going aperture is provided, the mask including a constricted neck portion between its upper and lower surfaces. Successive metal layers are applied over the substrate through the aperture in the mask sequentially by sputtering methods which form a metallic layer wider than the constricted neck portion of the mask and by vapor deposition method which forms a narrower metal layer corresponding to the transverse dimension of the constricted portion of the mask.

Method of encapsulating conductors

Disclosed is a multilayer capacitor consisting of a plurality of laminae with each of the laminae including a conductive plate portion and a non-conductive sheet portion. The conductive plate portion has at least one tab projecting to at least one edge of the conductive plate portion with the maximum number of tabs per conductive plate portion being limited to avoid excessive lateral congestion. The laminae are divided into different groups with the laminae from each group having the same number and location of tabs and with the laminae from different groups differing by at least the location of the tabs. The laminae are interleaved so that:
