1. A semiconductor analysis microchip configured to detect a fine particle in a sample liquid, comprising:

  • a semiconductor substrate;

    a first flow channel provided between a first insulating film and a second insulating film in the semiconductor substrate, into which the sample liquid is introduced, the first flow channel including a groove provided in the semiconductor substrate, the first insulating film being in direct contact with a bottom surface and side surfaces of the groove, and the second insulating film putting a lid on at least part of the groove;

    a second flow channel provided above the first flow channel, the second flow channel including a third insulating film at least partially stacked on the second insulating film; and

    a pore provided in the second insulating film between the first flow channel and the second flow channel to allow the fine particle in the sample liquid to pass therethrough, wherein the pore is not provided in the first insulating film.
