Products cooperation picture
1.The edge removal method involving the improvement of silicon slag and self-doping after the epitaxy of the substrate is carried out when the LTO back sealing layer is removed, and the chamfering parameter is set to within 300μm. Then HF corrosion is carried out, the volume of HF corrosion liquid is 40% ~ 50% of the volume X of the conventional edge removal corrosion liquid in the industry, and the corrosion time is 70% ~ 80% of the industry conventional edge removal corrosion liquid time Y. It is very innovative and practical to find a method to improve the silica slag and self-doping after the epitaxy of the substrate.
