  • Publication number: 20210391204
    Abstract: An insulating substrate has a sample holding surface. A support is bonded to the insulating substrate. A first through-hole in the insulating substrate and a second through-hole in the support are continuous with each other to serve as a gas inlet. A porous member is located in the second through-hole. The second through-hole has, at its opening adjacent to the insulating substrate (opening adjacent to the substrate), a larger diameter than the first through-hole. The opening of the second through-hole and an electrostatic attraction electrode are at different positions in a direction parallel to the sample holding surface. The electrostatic attraction electrode and the second through-hole avoid overlapping each other as viewed from above.
