Abstract: A manufacturing method of a semiconductor structure includes the following steps. Gate structures are formed on a semiconductor substrate. A source/drain contact is formed between two adjacent gate structures. The source/drain contact is recessed by a recessing process. A top surface of the source/drain contact is lower than a top surface of the gate structure after the recessing process. A stop layer is formed on the gate structures and the source/drain contact after the recessing process. A top surface of the stop layer on the source/drain contact is lower than the top surface of the gate structure. A semiconductor structure includes the semiconductor substrate, the gate structures, a gate contact structure, and the source/drain contact. The source/drain contact is disposed between two adjacent gate structures, and the top surface of the source/drain contact is lower than the top surface of the gate structure.
