[0003]
[0003] This disclosure is directed to a substrate container, specifically, a bracket for receiving and holding a diffusion device within such a substrate container.
[0004]
[0004] Even when the diffusion device is inserted from the outside of the substrate container, by having an opening larger than the holding area of the diffusion device bracket, the diffusion device can be received and guided to a predetermined position. This can reduce or eliminate the number of operations performed within the container body itself, and thus reduce the generation of particles or the introduction of contaminants that may result from such operations. As a result, the cleanliness of the substrate container is improved, and the resulting yield obtained from processing substrates using such containers in the process is improved.

In one embodiment, the third internal cross-sectional region and the first internal cross-sectional region are equal.
[0011]
[0011] In one embodiment, the bracket includes a plurality of openings along the length of the bracket.

The second internal cross-sectional region has a smaller total area than the first internal cross-sectional region defined by the receiving portion 302. The third internal cross-sectional region is equal to or larger than the cross-sectional region of the diffusion device at a point along the diffusion device that is configured to extend through the retaining region 304 when the diffusion device is fully inserted into the substrate container.
[0037]
[0040] The mounting tab 306 may extend from a portion of the bracket 300, including the first receiving portion 302 and the retaining region 304. The mounting tab 306 provides a region that enables the bracket 300 to be attached to a substrate container, for example, to the rear wall of the shell 102, as described above and as shown in Figure 1. In one embodiment, the mounting tab 306 may include a mounting point 308 into which the attachment to the substrate container is formed. In one embodiment, the entire mounting tab can be attached to the substrate container. Attachment of the mounting tab 306 or the mounting point 308 to the substrate container can be made via any suitable attachment (including, but not limited to, welding such as ultrasonic welding, mechanical interfaces such as corresponding engagement features, and the use of mechanical fasteners such as screws and adhesives).

[0039]
[0042] The bracket 300 may be located on the side of a substrate container that is configured, for example, to accept and hold only the left-side diffusion device or only the right-side diffusion device within the substrate container. A mirror image bracket of the bracket 300 may be provided and installed on a substrate container, such as the substrate container 100 described above and shown in Figure 1, to accept and hold the other of the left-side or right-side diffusion device.
[0040]
[0043] Figure 4 shows a flowchart of a method for providing a diffusion device in a substrate container according to one embodiment. Method 400 includes, in 402, inserting the diffusion device into an opening formed in the shell of the substrate container; in 404, guiding the tip of the diffusion device into a receiving portion of a bracket inside the substrate container; and in 406, inserting the diffusion device so that it extends through the holding region of the bracket. Method 400 can optionally be further repeated for each diffusion device to be installed in the substrate container.
[0041]
[0044] In 402, the diffusion device is inserted into an opening formed in the shell of the substrate container.

In one embodiment, the diffusion device can also be inserted in 402 through an opening in the bottom plate.
[0042]
[0045] The tip of the diffusion device is guided into the receiving portion of the bracket at 404. The tip of the diffusion device may be flat, hemispherical, or beveled, chamfered, or rounded, as shown in Figure 1. When this tip enters the bracket provided in the internal space of the substrate container, the tip can be guided so that it is within the range of the internal cross-sectional area defined by the receiving portion of the bracket (for example, the first receiving portion 202, the second receiving portion 204, or the receiving portion 302), as described above and shown in Figures 2 and 3.
[0043]
[0046] The diffusion device is inserted in 406 so as to extend within or through the retaining region of the bracket. As the diffusion device continues to be inserted through the bracket, it is guided by a narrowing internal cross-sectional region defined by the body of the bracket until its tip passes through the retaining region. Within the retaining region, the diffusion device is surrounded or in contact with the bracket so as to be held in a specific position and / or orientation by the bracket. In one embodiment, the tip of the diffusion device is within the retaining region of the bracket in 406 after insertion. In one embodiment, the tip of the diffusion device passes through the retaining region of the bracket, and a portion of the body of the diffusion device is located within the retaining region of the bracket after insertion in 406.
