Multilayer Filter, Multilayer Filter Assembly, and Methods for Forming a Multilayer Filter

Abstract: filters, filter assemblies, and methods of forming filters are provided. for example, a filter includes a plurality of dielectric layers stacked in a z-direction to form a substrate having a top and a bottom, and at least one conductive layer is formed over a dielectric layer. the conductive layer is positioned at a location along the z-direction between the top and bottom of the substrate that is about 200 �m or less from the bottom of the substrate. an assembly includes the filter attached to a device substrate. a method of forming the filter includes forming the dielectric layers and the at least one conductive layer, such as by forming the conductive layer over a dielectric layer, and stacking the plurality of layers to form a substrate with the conductive layer disposed about 200 �m or less from a bottom of the substrate.
