Abstract
Description
Technical Field

[0002] As one of the important equipment in semiconductor device process equipment, diffusion equipment is widely used in the production of integrated circuits, power electronics, solar cells and other industries. In the photovoltaic industry, high-temperature diffusion furnaces are mainly used to dope single-crystal silicon wafers and polycrystalline silicon wafers to form PN junctions. Annealing equipment is mainly used for annealing and activation. Low-pressure chemical vapor deposition (LPCVD) equipment is mainly used for thin film growth, which can be used for the growth of intrinsic amorphous silicon, doped amorphous silicon, silicon oxide and other thin films. The main function of plasma enhanced chemical vapor deposition (PECVD) equipment in the process flow of solar photovoltaic cells is thin film growth, which can be used for the growth of silicon nitride, aluminum oxide, intrinsic silicon, doped amorphous silicon and other thin films. One of the common features of diffusion equipment, annealing equipment and PECVD equipment is that they all need to push the boat with silicon wafers into the furnace tube and exit the furnace tube.
[0003] The existing conventional mechanism only fixes the paddle but does not seal it with the furnace door. The function of the independent paddle in this structure is only to serve as a vehicle for entry and exit. The furnace door is opened and closed and sealed independently. This method requires a paddle mechanism to realize the process of lowering and taking up the boat, and one process flow requires multiple actions of putting in the paddle, putting down the boat, taking out the paddle, putting in the paddle, taking out the boat, and taking out the paddle. There are many processes, and the risks of putting down and taking out the boat are increased. The paddle is sealed with the furnace door but not fixed. The paddle is inserted in the sealing cylinder and limited within a certain range, and the cylinder is sealed with the furnace door. As the positioning requirements of the mechanical structure of the equipment become higher and higher, and the safety requirements become higher and higher, the paddle position needs to be fixed.
