Description
- The present invention relates to a semiconductor substrate carrier and diffusion module thereof, and more particularly, to a substrate carrier and its air diffusion module for achieving clean effect by uniform flow gas in air chamber of the substrate carrier.
- Substrate and reticle are indispensable parts in semiconductor technology. Since the semiconductor structure is essentially a highly precise structure, the requirement for cleanliness in the manufacturing process per se are extremely fulfilled.
- Substrate plays an important role in being a base material for all semiconductor components. It includes common silicon substrate (such as wafer), glass substrate, ceramic substrate and even sapphire substrate. In the final microstructure produced by semiconductor fabrication are micron or even nano-scale structure, the manufacturing processes need to be operated under extremely precise environment, without any small particles attached, otherwise the yield of the final semiconductor components will be reduced.
- Carriers used for transporting components required for semiconductor manufacturing are required to have strict air tightness in order to prevent small particles from attaching to these components during loading or storage, thereby affecting the yield of semiconductor products. However, purely air-tight means that it can only passively prevent small particles from entering, but unable to actively exclude small particles which have been previously attached to base materials such as substrate or reticle. Therefore, most semiconductor containers carrying such materials will cooperate with the use of clean system to actively decrease the possible risk of small particles.
- In traditional technology, gas flowing in most semiconductor containers is achieved through the intake and outlet. With the intake and outlet of Extreme Clean Dry Air (XCDA), the previously attached particles are removed. Although it is feasible to control the gas flowing through the valve on the semiconductor container, there is still a risk that the gas cannot be completely cleaned b just by uniformly blown on the semiconductor material such as the substrate or reticle.
- In fact, the development of technology creates installing diffusion device with tubular or perforated structures in the semiconductor container. However, since most semiconductor containers already have a unified standard specification, most of the diffusion mechanisms that need to be installed inside the semiconductor containers need to be specially designed to avoid the bearing area of substrate or reticle. The design of the inner part of the semiconductor container also makes the replacement more inconvenient.
- To resolve the drawbacks of the prior arts, the present invention discloses a substrate carrier and its air diffusion module.
- The air diffusion module comprises a cover, at least one air intake part, an airtight layer, an air diffusion layer and a bearing portion. The at least one air intake part is connected with the cover. The airtight layer is connected with the cover and the at least one intake part. The air diffusion layer is covered by the cover through the airtight layer. The bearing portion is covered by the cover, the at least one intake part and the air diffusion layer. The bearing portion can be configured on a semiconductor container.
- According an aspect, the present invention proposes substrate carrier comprising a case, a door, at least one air intake and an air diffusion module.
- The case is provided with an opening, and the door is covered with the opening. The air diffusion module comprises a cover, at least one air intake part, an airtight layer, an air diffusion layer and a bearing portion. The at least one air intake part is connected with the cover and said at least one air intake. The airtight layer is connected with the cover and the at least one intake part. The air diffusion layer is covered by the cover through the airtight layer. The bearing portion is simultaneously covered by the cover, the at least one intake part and the air diffusion layer. The bearing portion is configured on the case.

airtight layer 103 is connected with theouter cover 101 and the at least oneintake part 102. Furthermore, theairtight layer 103 needs to be designed in conjunction with the shape of theouter cover 101 and the at least oneintake part 102 to reach the purpose of airtight.

The number and configuration of the at least oneintake airtight part 111 correspond to the at least oneintake part 102 and the at least oneintake part 111 is connected with theouter airtight part 108 to form an air tightness defense. In this way, the airtight environment during the operation of the present embodiment can be substantially ensured and moderate air pressure control can be achieved. - The
air diffusion layer 104 is tightly covered by theouter cover 101 through theairtight layer 103. In this embodiment, a filter material is selected for theair diffusion layer 104. Furthermore, it can be made of sintered polymer or other porous materials. The main function of theair diffusion layer 104 in this example is to maintain pressure and stabilize air pressure. After the pressure in the air chamber rises to a certain extent, the clean gas is blown uniformly and steadily through the filter material to achieve the effect of cleaning the inner part of thecontainer 200. - As shown in
FIG. 2 , the combined structural schematic diagram of theouter cover 101 and the at least oneintake part 102 is clearly shown inFIG. 2 . Because theouter cover 101 and theintake part 102 must be fixed to thebearing part 105 of thecontainer 200, in order to ensure that theintake part 102 can accurately engage with the bearingportion 105, theintake part 102 of the present embodiment is configured with at least onealignment part 112.

FIG. 3 , obviously, theair intake part 102 can be connected with theair intake 203, and the clean gas collected through theair intake 203 can be further entered into theair intake part 102. Under the protection of the double air-tight structure of the air-tight layer 103, the clean gas can enter the air chamber constructed by theouter cover 101 and theair diffusion layer 104. When the pressure of clean gas is raised to the preset threshold, it is blown evenly to thecase 204 to achieve the effect of gas diffusion cleanliness. - As is understood by a person skilled in the art, the foregoing preferred embodiments of the present invention are illustrated of the present invention rather than limiting of the present invention. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structure. While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
