Description

Technical Field

[0001] This utility model belongs to the technical field of wafer processing equipment, and specifically relates to a spin dryer. Background Technology

[0002] Currently, during the spin-drying process after polishing small-sized wafers, due to the lack of spin-drying racks of the corresponding size, the cassette is usually placed on an existing spin-drying rack holder for spin-drying. The existing spin-drying rack holders are mainly made of PFA material, which has the problems of high material cost and heavy weight.

[0003] In addition, the plug is placed on the upper side of the spin dryer frame, which prevents the plug and the wafer from being centered during spin drying. This results in poor dynamic balance during the spin drying process, which not only affects the service life of the spin dryer, but also may damage the wafer due to the large vibration.

[0004] In addition, the existing spin dryer rack has many closed positions on both sides, making it difficult to remove moisture from the wafer surface during spin drying, which affects the spin drying efficiency. At the same time, the existing spin dryer rack needs to be removed from the spin dryer, the plug needs to be fixed on the spin dryer rack, and then the rack needs to be inserted into the spin dryer for spin drying. The operation steps are cumbersome and affect the work efficiency. Utility Model Content

[0028] Limiting plate 4 is set on the top of base 1; both ends of limiting plate 4 are connected to two first baffles 3 respectively, so as to form a main body for placing the plug with base 1.

[0029] The first baffle 3 is provided with a first plug groove 6; the first plug groove 6 is connected to the cavity of the main body so that the plug can be inserted into the main body where the plug is placed through the first plug groove 6.

[0030] In this embodiment, a first baffle 3 is provided with a first baffle 5; a second baffle 7 corresponding to the first baffle 5 is provided on the limiting plate 4; the second baffle 7 cooperates with the first baffle 5 to limit the chip on the plug.

[0031] By using the above technical solution, the card is placed in the cavity inside the main body, and the first baffle 5 and the second baffle 7 limit the chip on the card, which can enhance the dynamic balance during the spin-drying process. The dynamic balance is better when the card is placed in the center. The hollow design of the drain groove 8, the first card groove 6 and the second card groove improves the spin-drying efficiency, makes the operation simpler, and improves the work efficiency.
