Abstract

The present invention relates to a station for measuring particle contamination of a transport carrier for conveying and storing semiconductor substrates at atmospheric pressure, said transport carrier comprising a rigid casing (2) containing an aperture and a removable door (3) allowing the aperture to be closed, the measuring station comprising:

a controlled environment chamber (4) comprising at least one load port (8) capable of coupling, on the one hand, to the rigid casing (2), and on the other hand, to the door (3) of the transport carrier, in order to move the door (3) into the controlled environment chamber (4) and bring the interior of the rigid casing (2) into communication with the interior of the controlled environment chamber (4); anda measuring module (5) comprising a particle measuring unit (14) and a casing-measuring interface (16) configured to couple to the rigid transport carrier casing (2) coupled to the controlled environment chamber (4) in the place of the door (3),characterized in that said casing-measuring interface (16) comprises a measuring head protruding from a base of the casing-measuring interface, bearing a first sampling orifice (12) connected to the particle measuring unit (14), and at least two injecting nozzles (20) configured to direct a gas jet onto at least two separate locations on the rigid casing (2) coupled to the controlled environment chamber (4), the respective orientations of the injecting nozzles (20) being fixed relative to the coupled rigid casing (2).
