Dig. No. 253-256 I disclosed that the low-pressure chemical fluorine phase deposition (LPCVD, lww pressure chemical 15 vapor deposition) string was deposited before the low temperature state. The thin silicon abdomen is then crystallized into polycrystalline silicon after a long 24 to 72 hours of annealing (a simple eal) treatment. This method is time-consuming, not only increases production costs but also increases the amount of heat in the product, and the growth chamber of the general low-pressure chemical vapor deposition (LPCVD) system is poor in cleanliness *. Therefore, the grown polycrystalline silicon and The quality of the thin-web of Si-20 Ge cannot be compared with the thin-web developed by ultra-high vacuum chemical vapor deposition (UHV / CVD, ultrahigh vacuum chemical vapor deposition) system.
