A physical unclonable function (PUF) generator including a substrate and semiconductor units is provided. Each of the semiconductor units includes an isolation structure, a first conductive line, and a second conductive line. The isolation structure is located in the substrate. The isolation structure has a first protrusion portion and a recess. The first protrusion portion and the recess are adjacent to each other. The first conductive line is located above the first protrusion portion and the recess. The second conductive line is located above the first conductive line. At least one short circuit randomly exists between at least one of the first conductive lines and at least one of the second conductive lines in at least one of the semiconductor units.
