[18]

4 Prevent the introduction of impurities for approximately two degree of elastic structure (24) comprises. Elastic structure (24) utilizing the sidewalls and a bottom of the solvent such as, for example bellows (bellows) can be used. Elastic structure (24) is the limiting completed on unwanted carrier (CR), carrier (CR) weight and elastic structure (24) movable unit, carrier (CR) on inspection (20) e-conducted as between, not through the second substrate. The latch key (latch key, 25) is fixed carrier cover (CV) are used. In particular, body (BD) and cover (CV) of the present invention in the embodiment upon engaging in once testing is complete, the latch key (25) react with each other.

[19]

An end portion of the carrier (CR) (30) (BD) is the main body once testing is complete and a cover (CV) combined with a carrier (CR) where outside the substrate processing are disclosed. An end portion (30) includes a stage (31), rail (32) and stage drive section (33) having a predetermined wavelength. Stage (31) comprises a stage drive section (33) by rail (32) reciprocating motion on each other. Stage drive section (33) can be implemented such as reciprocation of cylinder drive means. Wherein, stage (31) rail (32) described but moving on, other means, for example, conveyor belt, pinion, chain utilizing, stage (31) moves the disapproval.

[20]

Once testing is complete carrier (CR) includes a rotating part (28) is rotated by about 90 road stage (31) upon the substrate. Carrier (CR) stage (31) seated, rotating part (28) is extend from the back substrate. Carrier (CR) driving motor stage (31) a stage drive section (33) inspection using (20) up to the opposite, stage (31) the rails (32) along inspection (20) moves to opposite. Stage (31) is inspection (20) and moved opposite, stage (31) is in Figure 1 as the loading and the unloading (10) projecting radially more outward therefrom. Projecting stage (31) includes a carrier (CR) manually or automatically transfer system or stocker machine unit to be mounted on the substrate.

[21]

Figure 5 shows a of the present invention in the embodiment also by 3 to also output ports (40) between the carrier (CR) carried out to the process inspection embodiment representing a low oxide inclusion content. The, loading and the unloading (10) and inspection (20) is also 1 and 2 also reference the on-sensors other.

[22]

The also 3, inspection (20) is on the side of the vacuum pump (11) and connected, support (12) are supported. Vacuum pump (11) is in the loading and the unloading (10) can be located inside or outside of at least one of. Support (12) is mounted on a main body side projection where a carrier body (BD) end (13) located therein. Inspection (20) includes a support (12) being fastened to, adhered (27) close contact part is conically (26) moves up and down by of the week. Inspection cover (CV) includes a carrier (20) from one another by. The, inspection (20) lessen the carrier cover (CV) between a distance away disclosed. In other words, an adhesion unit (27) is increased in carrier cover (CV) is inspection (20) upon the substrate.

[23]

The also 4, contact part is conically (26) operates to a, carrier cover (CV) to descend inspection (20) maintaining a spacing diffuse to the adjacent b lessen. The, interval is less than the interval (a) (b). I.e., carrier cover (CV) is inspection (20) inside the moved into a position in other. Then, body side projection where a carrier body (BD) (13) loaded on substrate. A considerable, carrier body (BD) (CV) (c) and carrier cover between the inspection region formed therein. (C) inspecting the inspection RM joined substrate. If necessary, an inert gas, e.g. nitrogen gas purge is etched. Carrier body (BD) and cover (CV) on completion of the setting, inspection region (c) of the dopant introduction of number and humidity test substrate. If required, (c) supplying an inert gas is connected with the inspection region can be measured.

[24]

The also 5, once testing is complete, contact part is conically (26) (CV) (BD) covered by a flip-top body associates substrate. (BD) (CV) is combined with the cover on the body drawing that represents the state, cover body (BD) (CV) (CV) dashed into cover is not expressed. The coupled carrier (CR) rotating part (28) is rotated by about 90 road stage (31) upon the substrate. Carrier (CR) stage (31) seated, rotating part (28) is stored in the lungs. Carrier (CR) driving motor stage (31) a stage drive section (33) inspection using (20) up to the opposite side of the, stage (31) a rail (32) along inspection (20) moves to opposite. Stage (31) is inspection (20) and moved opposite, stage (31) is in Figure 1 as the loading and the unloading (10) projecting radially more outward therefrom. Projecting stage (31) includes a carrier (CR) manually or automatically transfer system unit or machine or stocker loaded, cleaning or again for the disposal position are confirmed each other.

[25]

By carrier inspecting method of the present invention in the embodiment cleaning, inspection and unloading between composed embodiment during to the lungs. In embodiment but is separate carrier inspecting device, embodiment of the present invention in the embodiment for reducing carrier cleaning between inspection is inserted disclosed. A considerable, carrier inspecting for up does not require a separate device. The, method of the present invention inspection device having at least a subset of the inspection time space can be efficiently utilized.

[26]

Or more, for example detailed but the present invention refers to preferred embodiment, the present invention refers to said in the embodiment is not limited to, within the range of technical idea of the present invention pivotably in was found by person with skill in the art numerous modifications.
