Abstract:
A high-frequency module, comprising:a substrate made with organic material and having multiple alternating pattern wiring layers and dielectric insulating layers made with organic material, a buildup surface layer on an upper surface of the substrate, an insulating layer on the buildup surface; and a high frequency element layer formed over the buildup surface, the high frequency element layer including an insulating layer on the buildup surface, and an inductor insulated from the buildup surface by the insulating layer, wherein, the substrate has a wiring pattern-free region void of any wiring pattern, the wiring pattern-free region extending from the upper surface to at least a mid section of the substrate along the thickness direction of the substrate, and the inductor of the high-frequency element layer is located directly above the wiring pattern-free region along the thickness direction of the substrate.
