Pre-annealing machines and ALD (atomic layer deposition) machines in the solar cell manufacturing industry.
Pre-Annealing Machine: Provides support and positioning for the cassette that holds silicon wafers before thermal processing. Ensures stable transfer into the annealing chamber.
ALD Machine: Acts as a guiding and alignment pin for wafer cassettes during atomic layer deposition (e.g., Al₂O₃ or SiNₓ passivation layers). Maintains precise positioning so wafers receive uniform coating.
