Abstract:
1. A testing and repairing apparatus of through silicon via (TSV) in a stacked-chip, adapted to test a first TSV structure disposed between a first chip and a second chip in the stacked-chip, the testing and repairing apparatus comprising: a first switch and a second switch, disposed in the first chip, wherein first terminals of the first switch and the second switch are coupled to a first terminal of the TSV structure, and a second terminal of the first switch is coupled to a function unit of the first chip; a third switch and a fourth switch, disposed in the second chip, wherein first terminals of the third switch and the fourth switch are coupled to a second terminal of the TSV structure, and a second terminal of the third switch is coupled to a function unit of the second chip; a first resistor, disposed in the first chip, wherein a first terminal of the first resister is coupled to a first voltage; a first selector, disposed in the first chip, and coupled between a second terminal of the second switch and a second terminal of the first resister; a second selector, disposed in the second chip, and coupled between a second terminal of the fourth switch and a second voltage; a first control circuit, disposed in the first chip, detecting the second terminal of the second switch, and controlling the first switch, the second switch and the first selector; and a second control circuit, disposed in the second chip, and controlling the third switch, the fourth switch and the second selector.
