1. A manufacturing method of an input circuit of a flip-flop, comprising:
depositing a first gate strip, a second gate strip, a third gate strip, and a fourth gate strip, wherein a distance between the first gate strip and the second gate strip, a distance between the second gate strip and the third gate strip, and a distance between the third gate strip and the fourth gate strip equal;
executing a cut-off operation upon the first gate strip to generate a first first gate strip and a second first gate strip, wherein the first first gate strip is a gate terminal of a first PMOS, and the second first gate strip is a gate terminal of a first NMOS;
executing a cut-off operation upon the third gate strip to generate a first third gate strip and a second third gate strip, wherein the first third gate strip is a gate terminal of a second PMOS and the second third gate strip is a gate terminal of a second NMOS; and
directing a first signal to the first first gate strip and the second third gate strip, and a second signal to the second first gate strip and the first third gate strip;
wherein directing the first signal to the first first gate strip and the second third gate strip, and the second signal to the second first gate strip and the first third gate strip comprises:
forming a first conductive strip connected between the first first gate strip and the second third gate to direct the first signal to the first conductive strip; and
forming a second conductive strip connected between the second first gate strip and the first third gate to direct the second signal to the conductive strip.
