  • Patent number: 11967519
    Abstract: An integrated semiconductor device includes a substrate, semiconductor circuit layers, a first insulating layer, a second insulating layer, and an interconnection layer. The semiconductor circuit layers are disposed above the substrate. The semiconductor circuit layers have device portions and isolating portions, and the isolating portions are located among the device portions. The first insulating layer is disposed on the semiconductor circuit layers, and the second insulating layer is disposed on the first insulating layer, and the interconnection layer is disposed on the semiconductor circuit layers. The interconnection layer penetrates the first and second insulating layers to electrically connect the device portions of the semiconductor circuit layers. The second insulating layer or the first and second insulating layers collectively form one or more isolating structures above the isolating portion of the semiconductor circuit layers.
