Abstract: A door locking mechanism and semiconductor container using the same include door panel, cover, and locking module. The door panel has a first stop structure. The cover and the door panel define an accommodating space for receiving the locking module. The locking module includes rotating member, holding member, and elastic member. The elastic member is disposed on the holding member and has a second stop structure near the first stop structure. The elastic member is disposed between the holding and the rotating member. The elastic member is compressed when a force is applied to the holding member, and the second stop structure detaches from a limitation state with the first stop structure for allowing a rotating operation of the rotating member. The elastic member elastically restores when the force is removed, and the second stop structure returns to the limitation state for limiting the rotating operation.

Abstract: A supporting shelf module includes a plurality of plastic supporting plates parallelly arranged in a height direction, and at least one pair of metal-made connectors located at two opposite ends of the supporting plates in the height direction. The connectors in one pair are correspondingly located in two horizontal planes perpendicular to the height direction. A wafer container is also disclosed, which includes a container body having at least two sets of the supporting shelf modules mounted therein, at least two top retaining brackets and at least two bottom retaining grooves provided on an inward side of a top and a bottom panel of the container body, respectively. The supporting shelf module has upper ends engaged with the top retaining brackets and lower ends engaged with and limited to the bottom retaining grooves in an engaging direction. Thus, the tolerance problem of the conventional wafer shelf can be solved.

Abstract: An optical measurement apparatus includes a thermal insulation housing, a first light-transmissive plate, a second light-transmissive plate, a heat-conductive layer, a cooling source and a photosensor.
