Abstract
In one embodiment, an electronic device includes first and second substrates, an insulating layer, and a connecting material. The first substrate includes a first conductive layer. The second substrate includes a basement having first and second surfaces, a second conductive layer on the second surface, and a first hole penetrating through the basement. The insulating layer is arranged between the first conductive layer and the basement, and has a second hole. The connecting material connects conductive layers via holes. The first hole has a first opening on a first surface side. The second hole has a third opening on a first conductive layer side which is larger than the first opening.
Claims20
An electronic device comprising:
- a first substrate which includes a first conductive layer;
- a second substrate which includes
- a basement which has
- a first surface opposed to the first conductive layer and separated from the first conductive layer, and
- a second surface opposite to the first surface,
- a second conductive layer which is arranged on the second surface, and
- a first hole which penetrates through between the first surface and the second surface;
- an insulating layer which is arranged between the first conductive layer and the basement, and has a second hole which is connected to the first hole;
- and
- a connecting material which electrically connects the first conductive layer and the second conductive layer via the first hole and the second hole, wherein
- the first hole has a first opening on a first surface side and a second opening on a second surface side,
- the second hole has a third opening on a first conductive layer side and a fourth opening on a basement side, and
- the third opening is larger than the first opening.
