After the silicon wafers are loaded, the carrier boat is sent into the reaction chamber of the process equipment for reaction; after the process is completed, the carrier boat is sent out from the process equipment. After the carrier boat is cooled, the silicon wafers are taken out from the carrier boat and re-loaded into the cassette, and then sent to the next process. At present, an independent automatic loading and unloading device + process equipment is usually used for combination.

[0003] Referring to the patent with the publication number CN114203611A, it discloses an automatic loading and unloading system for a vertical furnace and a vertical furnace body.

That is to say, the entire frame 1 is divided into two layers, the lower layer is the loading and unloading area 10, and the upper layer is the process area 11.

[0058] The loading and unloading device is arranged within the loading and unloading area 10, that is, the loading and unloading device is located in the lower layer of the frame 1.

The cassette wafer loading and unloading unit includes a cassette wafer loading and unloading conveyor module 2201, a cassette top tooth module 2202, and a cassette alignment module 2203. The cassette wafer loading and unloading conveyor module 2201 employs, including but not limited to, rail conveyance, etc., and a cassette seat can be configured on the rail. In this embodiment: The cassette wafer loading and unloading conveyor module 2201 has a first working position 2201a and a second working position 2201b. The cassette transfer unit 21 conveys the cassette loaded with wafers between the cassette conveyor unit 20 and the first working position 2201a of the cassette wafer loading and unloading conveyor module 2201; The cassette top tooth module 2202 and the cassette alignment module 2203 are arranged at the second working position 2201b of the cassette wafer loading and unloading conveyor module 2201. The cassette top tooth module 2202 is used to insert or eject wafers into or out of the cassette, and the cassette alignment module 2203 is used to align the wafers on the cassette top tooth module 2202. Therefore, the cassette top tooth module 2202 is arranged below the second working position 2201b of the cassette wafer loading and unloading conveyor module 2201, and the cassette alignment module 2203 is arranged above the second working position 2201b of the cassette wafer loading and unloading conveyor module 2201. The cassette loaded with wafers that needs to be processed is conveyed from the first working position 2201a of the cassette wafer loading and unloading conveyor module 2201 to the second working position 2201b of the cassette wafer loading and unloading conveyor module 2201. The cassette top tooth module 2202 first ejects the wafers in the cassette, and then the cassette alignment module 2203 aligns the wafers on the cassette top tooth module 2202, facilitating the wafer transfer module 222 to transfer the wafers to the boat wafer loading and unloading unit; Similarly, the wafer transfer module 222 transfers the wafers that have completed the process to the second working position 2201b of the cassette wafer loading and unloading conveyor module 2201 and places them on the cassette top tooth module 2202 ejected from the cassette. The cassette alignment module 2203 first aligns the wafers on the cassette top tooth module 2202, the cassette top tooth module 2202 descends, the wafers are reinserted into the cassette, and then the cassette is conveyed to the first working position 2201a of the cassette wafer loading and unloading conveyor module 2201, waiting for the cassette transfer unit 21 to convey.

The wafer transfer module 222 conveys wafers between the second working position 2201b of the cassette loading and unloading conveyor module 2201 and the first working position 2211a of the wafer loading and unloading conveyor module 2211; The carrier top tooth module 2212 and the carrier alignment module 2213 are arranged at the end of the first working position 2211a of the wafer loading and unloading conveyor module 2211 (before the beginning of the second working position 2211b). The carrier top tooth module 2212 is used to insert or eject wafers into or from the carrier, and the carrier alignment module 2213 is used to align the wafers on the carrier top tooth module. Since the carrier top tooth module 2212 cannot insert or eject all the wafers in the carrier at one time, therefore, the carrier top tooth module 2212 will first perform wafer loading and unloading on the carrier at the end of the first working position 2211a of the wafer loading and unloading conveyor module 2211. As the carrier is conveyed from the first working position 2211a to the second working position 2211b of the wafer loading and unloading conveyor module 2211, the carrier top tooth module 2212 gradually performs wafer loading and unloading on the conveyed carrier. The wafers to be processed are conveyed from the cassette top tooth module 2202 to the first working position 2211a of the wafer loading and unloading conveyor module 2211 and placed on the carrier top tooth module 2212 ejected from the carrier. The carrier alignment module 2213 first aligns the wafers on the carrier top tooth module 2212. The carrier top tooth module 2212 descends, and the wafers are inserted into the carrier. Then the carrier is conveyed to the second working position 2211b of the wafer loading and unloading conveyor module 2211, waiting to be conveyed by the carrier conveying device; Similarly, the carrier conveying device conveys the carrier loaded with wafers after the process is completed to the second working position 2211b of the wafer loading and unloading conveyor module 2211 and conveys it to the first working position 2211a of the wafer loading and unloading conveyor module 2211. The carrier top tooth module 2212 first ejects the wafers in the carrier, and the carrier alignment module 2213 then aligns the wafers on the carrier top tooth module 2212, facilitating the wafer transfer module 222 to transfer the wafers to the cassette loading and unloading unit.

The boat transfer unit 42 is connected between the pair of second guide rod units 41 and can move between the pair of second guide rod units 41. The driving unit is used to drive the pair of second guide rod units 41 and the boat transfer unit 42 to move. In this way, the second guide rod unit 41 moves up and down on the first guide rod 40, driving the boat transfer unit 42 to move up and down. At the same time, the boat transfer unit 42 moves left and right between the pair of second guide rod units 41, so as to realize the transfer in the up, down, left, and right directions.

[0075] In a preferred embodiment of this embodiment: The second guide rod unit 41 includes a second fixed guide rod 410 and a second telescopic guide rod 411. The second fixed guide rod 410 is connected to the first guide rod 40 in a vertically movable manner. The second telescopic guide rod 411 is connected to the second fixed guide rod 410 in a left - right movable manner. The boat transfer unit 42 is connected to the pair of second telescopic guide rods 411 in a movable manner. Since the second telescopic guide rod 411 can move on the second fixed guide rod 410 and can move left or right relative to the second fixed guide rod 410. At the same time, the boat transfer unit 42 can also move left or right on the second telescopic guide rod 411, so that the moving range of the boat transfer unit 42 in the left - right direction is larger, meeting the transfer requirements of each position.

[0076] In another preferred embodiment of the present embodiment: The boat transfer unit 42 includes a connecting rod 420 and a hook portion 421. The connecting rod 420 is movably connected between the second telescopic guide rods 411 of a pair of second guide rod units 41. The hook portion 421 is connected to the connecting rod 420 and is used for hooking the boat. The hook portions 421 are usually arranged in pairs, and a pair of hook portions 421 hook the hanging ears at both ends of the boat. Multiple groups of hook portions 421 are provided, so that multiple groups of boats can be transferred simultaneously on one connecting rod 420. In the figure, 2 groups of hook portions 421 are provided, and 2 groups of boats can be transferred simultaneously.

[0077] As Figure 2 shown: Looking at the entire loading and unloading device, process device, and boat transfer device 4, the flower basket conveying unit 20 is located below the gas source and tail gas treatment unit 32; the flower basket transfer unit 21 is located below the process furnace 31; the inserting and removing wafer unit is basically located below the process furnace 31, but the second working position 2211b of the boat inserting and removing wafer conveying module extends below the paddle transfer unit 30. At the same time, the boat buffer unit is also located below the paddle transfer unit 30. That is to say, the second working position 2211b of the boat inserting and removing wafer conveying module, the boat buffer unit, and the paddle transfer unit 30 are distributed vertically, which is more convenient for the boat transfer device 4 to transfer between the three.

[0078] Comparative example and embodiment:

[0079] Taking a case where an automated loading and unloading machine and a process machine (with 6 furnaces distributed vertically) are connected in series as an example, where: Automated loading and unloading machine: length 10.5 meters, width 3 meters, height 2.2 meters; Process machine: length 15 meters, width 2.2 meters, height 4.5 meters. After being connected in series, the whole machine occupies a length of 25.5 meters, a width of 3 meters, and a height of 4.5 meters.

[0080] Taking a process and automated loading and unloading integrated machine (6 furnaces in 2 rows and 3 columns) as an example, under the same conditions, the whole machine occupies a length of 12 meters, a width of 3 meters, and a height of 4.5 meters.

[0081] Obviously, with the width and height remaining basically unchanged, the length of the whole machine can be shortened by nearly half, greatly reducing the size of the equipment.
