Zusammenfassung: | The invention provides a three-dimensional integrated wafer and a test method thereof, and a three-dimensional integrated chip, and the three-dimensional integrated wafer comprises a wafer assembly which is composed of a plurality of wafer layers, and the wafer layers are stacked and are connected through a connection structure. The wafer assembly comprises a plurality of chip units, the periphery of each chip unit is provided with the detection loop, and the detection loop is configured to detect the connection condition of the plurality of wafer layers in each chip unit. The structure can effectively monitor the layering problem of the wafer in the chip, and improves the yield of the chip.
