The ring-shaped magnetic element is placed in the ring-shaped concave portion. The adhesive layer covers the first metal portions and the ring-shaped magnetic element. The conductive portions are formed on the adhesive layer. The conductive channels penetrate the conductive portions, the adhesive layer, and the substrate, and are respectively located in an inner wall (122) and outside an outer wall (124) of the ring-shaped concave portion. Each of the conductive channels includes a conductive film (152) electrically connects to the aligned conductive portion and second metal portion.

Abstract:
A parallel resonant circuit is realized by stacking first to fourth wiring patterns (MS21,MS22,MS23,MS24) each having at least an inductance element. One of the adjacent first and second wiring patterns is set to a signal input node (Nin) and the other thereof is set to a signal output node (Nout). Then, the signal input node is connected to the signal output node via inductance elements of the first wiring pattern, third wiring pattern, fourth wiring pattern and second wiring pattern in order. By adjacently forming wiring layers of the signal input and output nodes, a capacitance value between the input and output nodes is increased compared to that when they are separated. Also, by increasing the line width of the first and second wiring patterns, the capacitance value can be further increased. Therefore, it is possible to achieve a large capacitance value in a small area and downsizing of the electronic device.
Abstract:
According to the invention, a microperforation (PMP) process step is combined with the lamination process. To this end, a dielectric layer (11,11') and a prefabricated product (1) are placed between two perforation dies (21,23) or a support and a perforation die. The prefabricated product (1) is partially covered by a conducting layer forming structures to be contacted by microvias. Pressure is applied on the perforation die (21,22), perforation tips of the perforation dies forming microvias for contacting the structures. A surface of the dielectric layer (11,11') or the prefabricated product (1) is configurated or coated to in a manner that the prefabricated product (1) and the dielectric layer (11,11') stick to each other after the pressure has been applied.
