Abstract
A semiconductor device includes a semiconductor substrate in which a through hole is formed, a first wiring, an insulating layer, and a second wiring that is electrically connected to the first wiring in an opening of the insulating layer. The insulating layer has a first curved portion that covers an inner surface of a through hole between a first opening and a second opening and a second curved portion that covers an edge of the second opening. A surface in the first curved portion is curved in a convex shape toward the side opposite the inner surface of the through hole. The surface in the second curved portion is curved in a convex shape toward the side opposite the inner surface of the through hole.
