Abstract:
1. A method for producing an electromagnetically shielded laminated structure having at least one RF-chip, the RF-chip having a surface area, said method comprising: securing the RF-chip in an embedding layer of the laminated structure, the embedding layer having a first side and an opposing second side; providing at least one first further layer to the first side of the embedding layer, wherein the first further layer has a first surface and a second surface, and the first surface is disposed adjacent to the first side of the embedding layer, forming a first interface layer; providing at least one second further layer to the second side of the embedding layer; wherein the second further layer has a first surface and a second surface, and the first surface is disposed adjacent to the second surface of the embedding layer, forming a second interface layer; providing an electrically conductive connector circuit in at least one of two interface layers; providing electrical connections between the RF-chip and the exterior of the laminated structure via the connector circuit in said at least one interface layer and a plurality of micro-vias through at least one of the further layers; and providing a first electrically conductive layer on the second surface of the first further layer, the first electrically conductive layer having a first area larger than the surface of the RF-chip, and a second electrically conductive layer on the second surface of the second further layer, the second electrically conductive layer having a second area larger than the surface area of the RF-chip such that the RF-chip is positioned between the first and second electrically conductive layer with the first and second areas for electromagnetic shielding.
