Abstract
An electronic device includes a plurality of stacked substrates. Each of the substrates includes a semiconductor substrate, a columnar conductor, and a ring-shaped insulator. The columnar conductor extends along a thickness direction of the semiconductor substrate. The ring-shaped insulator includes an inorganic insulating layer mainly composed of a glass. The inorganic insulating layer fills a ring-shaped groove that is provided in the semiconductor substrate to surround the columnar conductor.
