Claim 19:
20. The method according to claim 19, wherein forming a first structural layer on the substrate, and forming a corresponding single-hole liquid storage cavity, liquid resistance flow channel and buffer flow channel for each molecular detection unit in the molecular detection chip in the first structural layer; and the buffer flow channels of a plurality of molecular detection units in each row of molecular detection units being communicated with each other as a common buffer flow channel comprises:
forming a liquid resistance flow channel sacrificial structure at a preset position on the substrate for each molecular detection unit in the molecular detection chip;
forming the first structural layer on the substrate and the liquid resistance flow channel sacrificial structure, and forming the corresponding single-hole liquid storage cavity and buffer flow channel for each molecular detection unit in the molecular detection chip in the first structural layer, and the buffer flow channels of the plurality of molecular detection units in each row of molecular detection units being communicated with each other as a common buffer flow channel; and
removing the liquid resistance flow channel sacrificial structure in each molecular detection unit.
