Abstract:
1. A semiconductor structure, comprising; a second chip, having a second active surface and at least one second conductive pad, wherein the second conductive pad is exposed to the second active surface; a first chip, disposed on the second chip, and having a first active surface, a first back surface opposite to the first active surface and at least one first conductive pad, wherein the first conductive pad is exposed to the first active surface, and has at least one through hole; a groove, disposed in the first chip, communicating with the through hole of the first conductive pad, and exposing the first conductive pad and the second conductive pad; a through via, having opposite upper and lower surfaces, disposed in the groove, and electrically connecting the first conductive pad and the second conductive pad; and at least one electrical connecting element, disposed on the first back surface of the first chip, and electrically connected to the through via; wherein the upper surface of the through via directly contacts the at least one electrical connecting element, and the lower surface of the through via directly contacts the second conductive pad.
