| 摘要 |
An electronic component includes a semiconductor substrate having a first surface and a second surface opposite to the first surface, a cavity that penetrates from the first surface to the second surface of the semiconductor substrate, and an electrical mechanical element that has a movable portion formed above the first surface of the semiconductor substrate so that the movable portion is arranged above the cavity. The electronic component further includes an electric conduction plug, which penetrates from the first surface to the second surface of the semiconductor substrate, and which is electrically connected to the electrical mechanical element.
