Problems solved by technology

However, this method similar to lateral traction tends to generate an offset force in the moving direction of the movable pin 231, which will cause it to fail to be inserted into the socket of the box body 10, so that the box body 10 and the door body 20 cannot be connected. cover
At the same time, it will also increase the manufacturing cost of the front open wafer box

Abstract

The invention relates to a front open type wafer box with a latch and an airtight structure, mainly comprising a box body and a door body, wherein the box body is internally provided with a pluralityof slots for placing a plurality of wafers; an opening is formed on one side of the box body and used for the input and output of the plurality of the wafers; the door body is provided with an external surface and an internal surface; and the internal surface of the door body is combined with the opening of the box body to protect the plurality of the wafers placed in the box body. The front opentype wafer box is characterized in that the door body is internally provided with at least a latch structure, and the periphery of the internal surface of the door body is provided with an inflatableairtight piece.

Description

technical field [0001] The present invention relates to a front-opening wafer box, in particular to a front-opening wafer box with a latch inside the door body and an inflatable airtight member on the inner surface of the door. Background technique [0002] Semiconductor wafers will be transported to different workstations due to the need to go through various processes and to cooperate with process equipment. In order to facilitate the handling of wafers and avoid contamination from the outside, a sealed container is often used for transportation by automated equipment. Please refer to figure 1 Shown is a schematic diagram of a known wafer box. This wafer pod is a front opening type wafer pod (Front Opening Unified Pod, FOUP), which has a box body 10 and a door body 20, inside the box body 10 is provided with a plurality of slots 11 which can accommodate multiple a wafer, and on one side of the box body 10, there is an opening 12 for loading and unloading of the wafer; ...
