Boat Receiver is specifically used in the Pre-Annealing Machine and ALD (Atomic Layer Deposition) Machine in the solar cell manufacturing industry.
Pre-Annealing Machine: Holds and transfers the quartz wafer boat carrying solar cells. Ensures stability during thermal treatment before main diffusion or passivation.
ALD Machine: Acts as the interface for moving wafer boats into the ALD chamber. Provides precise alignment to ensure uniform thin film deposition (like Al₂O₃ layers for passivation).
