Abstract
To provide a semiconductor device having a structure suitable for higher integration. This semiconductor device includes: a first semiconductor substrate; and a second semiconductor substrate. The first semiconductor substrate is provided with a first electrode including a first protruding portion and a first base portion. The first protruding portion includes a first abutting surface. The first base portion is linked to the first protruding portion and has volume greater than volume of the first protruding portion. The second semiconductor substrate is provided with a second electrode including a second protruding portion and a second base portion. The second protruding portion includes a second abutting surface that abuts the first abutting surface. The second base portion is linked to the second protruding portion and has volume greater than volume of the second protruding portion. The second semiconductor substrate is stacked on the first semiconductor substrate.
