Semiconductor device with an antenna and fabrication method therefor

摘要

A semiconductor device with an antenna comprises one or more antenna units (20) for sending and receiving signals and a semiconductor element (12) electrically connected to the antenna units (20). The antenna units (20) are formed by pressing or etching a thin metal sheet having substantially the same flat surface size as the semiconductor element (12), and the antenna units are integrally coupled to the surface of the semiconductor elements (12). When the antenna units (20) are formed in a plurality of layers they are separated by insulating layers (16), and the antenna units (20 a,b,c) formed on the respective layers are connected electrically in series with each other.
