Abstract:
Method for producing a conductor structural element with a layer sequence having an internal layer substrate, including the steps: providing a rigid carrier having an underside and a top side; defining a cut-out section on the rigid carrier; applying at least one electrically insulating layer with a recess in such a way that the cut-out section is exposed; placing an internal layer substrate above the cut-out section with formation of a cavity between the rigid carrier and the internal layer substrate; aligning and fixing the internal layer substrate relative to the rigid carrier; laminating the layer construction prepared in this manner such that resin material of the at least one electrically insulating layer liquefies and encloses the internal layer substrate with the cavity being left free; producing a cut-out by cutting the cut-out section out of the rigid carrier from the outer underside of the rigid carrier.

An electronic component includes dielectric layers laminated along a lamination direction and shield electrodes. The dielectric layers include first and second dielectric layers. The side surfaces of the first dielectric layer are not covered with the shield electrodes. The side surfaces of the second dielectric layer are covered with the shield electrodes. The dielectric constant of the first dielectric layer is lower than the second dielectric constant of the dielectric layer.

Abstract:
A wiring substrate includes wiring layers and insulation layers alternately stacked. Via holes are formed in the insulation layers. First via wirings are formed in the via holes to electrically connect the wiring layers to one another. Through holes extend through a lowermost one of the insulation layers in a thickness direction. The lowermost insulation layer covers a lowermost one of the wiring layers. Second via wirings are formed in the through holes to define an identification mark that is identifiable as a specific shape including a character, a symbol, or a combination thereof. A lower surface of each of the second via wirings is exposed from a lower surface of the lowermost insulation layer and is flush with a lower surface of the lowermost wiring layer.
