Original Abstract Submitted
A semiconductor device includes: a first chip including a first circuit; a second chip disposed to be spaced apart from the first chip in a first direction and including a second circuit; and a transformer chip disposed over the first chip and including a transformer. The first circuit and the second circuit are configured to transmit a signal or power via the transformer. The transformer chip includes: an element insulating layer; and an outer coil and an inner coil disposed as the transformer in the element insulating layer. The inner coil is disposed inside the outer coil so as not to overlap the outer coil when viewed from a thickness direction of the element insulating layer.
