Abstract
Description
Technical Field
[0001] This application relates to the field of atomic layer deposition, and particularly relates to a spraying device and a deposition apparatus. Background Art
[0002] In a photovoltaic atomic layer deposition apparatus, the deposition reaction mainly occurs in a stainless steel chamber. The chamber consists of an inner cavity and an outer cavity. There is a heating plate between the inner cavity and the outer cavity to heat the chamber, and the outer cavity is cooled by cooling water. In the inner cavity, the workpiece is deposited by spraying. The spraying method is to supply gas from the front end of the inner cavity through a spraying plate and extract gas at the tail of the inner cavity to ensure that the noble gas can flow uniformly in the inner cavity. As the size of the workpiece (photovoltaic panel) increases, the reaction chamber also becomes larger. To achieve film thickness uniformity and improve production efficiency, the size of the spraying plate also increases accordingly, and thus the spraying plate becomes heavier. During actual use, the spraying plate will sag, and the spraying plate itself will deflect at a certain angle. The poor connection between the spraying plate and the noble gas pipeline will cause the reaction gas to leak, and in severe cases, it will affect the flow field in the inner cavity, thereby affecting the process effect.

In this embodiment, the upper end of the mounting seat is connected to the lower end of the spraying member 20, and a sliding assembly, such as a slide rail and a slider, can be provided between the mounting seat and the bracket 30; the sliding assembly includes a slide rail provided on the bracket 30 and a slider provided on the mounting seat, and the slide rail is adapted to the slider.
[0031] Of course, a rolling assembly, such as a universal wheel and a rolling bearing 45, can also be provided on the mounting seat. The lower end of the spraying member 20 is supported by the support mechanism 40, which can avoid deflection caused by self-weight sagging, ensure the sealing performance of the connection between the spraying member 20 and the gas path when the door body 10 is closed, and reduce the leakage of precious gas. When the spraying member 20 slides relative to the door body 10, the mounting seat can slide or roll relative to the bracket 30 to ensure that the support mechanism 40 can stably support.
[0032] In some embodiments, referring to Figures 1 to 4 , the rolling member includes a rolling bearing 45 rotatably provided on the mounting seat. A receiving groove 41 is provided at the upper part of the mounting seat, the receiving groove 41 is adapted to the spraying member 20, the mounting seat is provided with a receiving groove 44, and the support mechanism further includes a shaft body 46 provided in the receiving groove 44. The rolling bearing 45 is provided on the shaft body 46 and is located in the receiving groove 44. In this embodiment, the spraying member 20 can be a spraying plate arranged parallel to the door body 10, and the length direction of the receiving groove 41 is perpendicular to the length direction of the receiving groove 44. The lower end of the spraying plate can be inserted into the receiving groove 41, and a screw 42 is further provided on the side wall of the receiving groove 41. By screwing the screw 42 so that its end abuts against the spraying plate, the mounting seat can be fixed on the spraying plate. The shaft body 46 penetrates through the two side walls of the receiving groove 44 and is fixed by a snap ring. The rolling bearing 45 is provided in the receiving groove 44, the inner ring thereof cooperates with the shaft body 46, and the outer ring can roll as the spraying plate moves.
[0033] In addition, the support mechanism 40 further includes a height-adjusting member 43 threadedly connected to the mounting base.

Two extending portions are formed by the bottom of the receiving groove 41 extending outward along the length direction, and the height-adjusting member 43 is disposed on the extending portions. When installing the support mechanism 40, the mounting base and the spraying plate can be inserted into each other first, and the rolling bearing 45 is supported by the bracket 30. Then, by screwing the height-adjusting member 43, the height of the height-adjusting member 43 in the receiving groove 41 can be adjusted to ensure that the height-adjusting member 43 can support the spraying plate and prevent the spraying plate from sagging.

In some embodiments, the spraying device further includes a sliding bearing 21 disposed on the door body 10, and a guide rod 22 with one end disposed on the spraying member 20. The guide rod 22 cooperates with the sliding bearing 21. The spraying device further includes an elastic member 23 sleeved outside the guide rod 22. One end of the elastic member 23 abuts against the spraying member 20, and the other end abuts against the door body 10. The elastic member 23 can be a spring, and the elastic force of the spring can make the spraying member 20 away from the door body 10. When the door body 10 is closed, the elastic force can also ensure that the spraying member 20 is in close contact with the gas supply pipeline on the furnace body 50, further reducing the leakage of precious gas.
[0035] It should be noted that the guide rod 22 can be disposed near the two side edges of the spraying plate. The support mechanism 40 is disposed directly below the guide rod 22. Specifically, a pair can be provided and are respectively close to the two sides of the spraying plate to ensure balanced stress on both sides of the spraying plate and reduce the friction between the guide rod 22 and the linear bearing.

One end of the furnace body 50 is provided with an opening for the bracket 30 to enter and exit, and the door body 10 is used to close the opening. An air path for docking with the spraying plate is also provided at the opening. When the door body 10 is closed, the spraying plate is docked with the air path, and the precious gas can be transported to the spraying plate through the air path. When the spraying plate is docked with the air path, it slides towards the door body 10, and the spring is compressed. The elastic force is used for the spraying plate to dock with the air path. When the spraying plate slides towards the door body 10, the lower support mechanism 40 plays a role of rolling support and guiding.
