AI Technical Summary
In existing technologies, the furnace door of semiconductor process equipment sags due to bearing deformation, affecting the sealing effect of the furnace opening, and the problem is more serious in large-size equipment.
The structure employs a lifting shaft and rotating components with first and second channels to reduce heat transfer to the bearings. Crossed roller bearings or deep groove ball bearings are used, combined with microswitches and proximity switches to achieve stable opening and closing of the furnace door.
It improves the positional stability of the furnace door, enhances the sealing effect of the furnace opening, reduces the escape of high-temperature gas from the process chamber, and lowers heat loss.
