Abstract

A vacuuming pipe structure of a wafer placement seat, which matches with a machine vacuuming device for externally connecting to a wafer placement seat having a vacuum conduit for carrying out the vacuuming operation of the wafer placement seat, which comprises: an installation section being an assembly of a block, a pipeline and a fastening element for matching with other elements of the vacuuming device; a guide pipe being a longitudinal hollow pipeline, one end of which is connected to the installation section, and the hollow through hole thereof being the air passage for the vacuuming operation; and an insertion pipe being a short hollow pipeline, one end of which is connected to the other end of the guide pipe, the hollow through hole thereof and the hollow through hole of the guide pipe forming a connected air passage, the outside diameter thereof being smaller than the outside diameter of the guide pipe and the inside diameter of the vacuum conduit but close to the inside diameter of the vacuum conduit, for being inserted into the vacuum conduit during the vacuuming operation.
