Abstract:
1. A 3D integrated circuit structure, comprising: a first chip structure, which comprises a first semiconductor substrate, a first insulating layer, and a first detection structure, wherein: the first insulating layer is located on the first semiconductor substrate, and the first detection structure is embedded into the first insulating layer; the first detection structure comprises detection bodies positioned on two sides of the first insulating layer, the detection body comprising a first conductor, at least two second conductors, and at least one third conductor; the first conductor is located on a side of the first insulating layer and connected with ends of the second conductors, the third conductors are formed between the second conductors and insulated from the second conductors, and the first ends of the third conductors away from the first conductor are step-wise; and the lengths of individual portions of the third conductors facing the second conductors are equal, and in the direction of the length of the third conductors, the distances between the projections of the first ends which are corresponding to each other and located on the detection bodies on the two sides are substantially the same.
