Horizontal Diffusion/Oxidation/Annealing Equipment
The equipment is mainly used for doping and form PN junctions on silicon wafers in the manufacturing process of crystalline silicon solar cells.
Prepare quartz boat & wafers→ Insert wafers→ Loading wafers→ Choose recipe → Boat loading→ tube Vacuuming→ Temperature rising→ Oxygen inlet→Pocl3 inlet→ Push in→ DOA treatment→ Boat unloading→ Cooling→ Testing→ Wafer unloading.
