SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE

原文（中文）

A semiconductor device having favorable electrical characteristics is provided. The semiconductor device includes a transistor including a gate electrode, a source electrode, and a drain electrode; a first insulator over the transistor; a second insulator over the first insulator; a third insulator over the second insulator; a first electrode in contact with the top surface of the source electrode; and a second electrode in contact with the top surface of the drain electrode. The second insulator includes a first opening portion overlapping with the source electrode and a second opening portion overlapping with the drain electrode. The third insulator is in contact with the side surface of the second insulator and the top surface of the first insulator inside the first opening portion and the second opening portion. The first electrode is positioned through the first opening portion. The second electrode is positioned through the second opening portion.
