Abstract:
1. A method of making a multilayer device, comprising: in a layer of the multilayer device, providing at least one reference plane, wherein the at least one reference plane is either a voltage plane or a ground connection plane; providing in the layer a plurality of vies connecting the layer in the multilayer device with at least one other layer in the multilayer device, wherein the layer has a via clearance area between the associated with each via in the plurality of vies, the via clearance area providing a space between an associated via in the plurality of vias and the at least one reference plane such that the associated via does not contact the at least one reference plane, the via clearance area comprising a dielectric material; and providing at least one a floating support member in each via clearance area in the layer between the associated via in the plurality of vies and the at least one reference plane, wherein: the floating support member encircles the associated via in the plurality of vies, wherein the floating support member is not electrically connected to the associated via or the at least one reference plane, and the floating support member is not .electrically connected to the at least one reference plane, wherein the at least one floating support member has a ring configuration in the layer.
