Semiconductor device, method of manufacturing semiconductor device, and electronic device

摘要

A semiconductor device includes a semiconductor element (2) and an electronic element (3). The semiconductor element has a first protruding electrode (2a), and the electronic element has a second protruding electrode (3a). A substrate (4) is disposed between the semiconductor element (2) and the electronic element (3). The substrate has a through-hole (4a) in which the first and second protruding electrodes (2a, 3a) are fitted. The first and second protruding electrodes are connected together inside the through-hole (4a) of the substrate.
