Abstract

A semiconductor chip includes a lower wiring layer, a multilayer wiring layer formed on the lower wiring layer, and an upper wiring layer formed on the multilayer wiring layer. Here, a thickness of a wiring provided in the lower wiring layer is larger than a thickness of each of a plurality of wirings provided in the multilayer wiring layer, and a thickness of a wiring provided in the upper wiring layer is larger than the thickness of each of the plurality of wirings provided in the multilayer wiring layer. A lower inductor which is a component of a transformer is provided in the lower wiring layer, and an upper inductor which is a component of the transformer is provided in the upper wiring layer.
