Clean container structure

Abstract

A clean container is disclosed. A bracing frame is placed into the clean container directly from it's front opening, which is made integrally with the inner chamber of the clean container. There is an upper assistant plant at the upper part of the container and there is a lower assistant plate at the lower part of the container. The two plates are combined with the bracing frame. Advantages: simple production and assembling, good structure strength and air tightness.

Description

technical field [0001] The invention relates to a clean container structure, in particular to a clean container structure which is suitable for rationalizing the transmission mode of load-carrying force, and can improve structural strength and precision, air tightness, and electrostatic protection. Background technique [0002] At present, the wafers produced by the semiconductor factory are often accommodated and arranged horizontally in a wafer boat. The wafer boat has a plurality of supporting flanges and can be used to insert multiple wafers. The lower side plate of the clean container body is then covered by the cover of the clean container body to protect each wafer, so that it can maintain ultra-high cleanliness during the process of transmission, storage, loading and unloading during production and manufacturing environment without being polluted by particulate dust. [0003] see figure 1 , which is a three-dimensional exploded view of a known clean container struc...

Problems solved by technology

[0004] However, the design in which an upper assembly hole 913 and a lower assembly hole 914 are directly provided on the upper side plate 911 and the lower side plate 912 of the clean container body 91 is not only difficult and expensive to manufacture and assemble, but also It is also easy to cause the structural strength of the clean container body 91 to be damaged

In addition, the clean container body 91 has too many openings and the area is too large, and the airtightness of the inner chamber 910 is also easily affected, so it is easy to cause external moisture or dust particles to enter, which is not very ideal, and can only be added. Airtight gasket to strengthen its airtight effect

In addition, since there are too many dead angles in components such as the clean container body 91, it is easy to cause the phenomenon that cleaning and drying are not easy when using related cleaning equipment for cleaning.
