Abstract
A semiconductor structure, including a substrate and multiple chips, is provided. The chips are stacked on the substrate. Each of the chips has a first side and a second side opposite to each other. Each of the chips includes a transistor adjacent to the first side and a storage node adjacent to the second side. Two adjacent chips are bonded to each other. The transistor of one of the two adjacent chips is electrically connected to the storage node of the other one of the two adjacent chips to form a memory cell.
