Seeing everyone’s enthusiasm for knowledge about polysilicon, I would like to recommend the following books: 1. \"Handbook of Electronic Industry Production Technology (6) – Semiconductors and Integrated Circuits\", 2. \"Polysilicon Technology\", 3. \"Questions and Answers on Distillation Operations\", 4. \"Тетрахлорсилан трихлорсилан\", 5. \"Металлургия поликристаллического кремния высокой чистоты\". The first three are available, while the last two are in their original Russian version; I hope that some friends can upload them. Mine is a photo; it’s too big. Everyone can also take a look at Volumes 7 and 8 of the Electronic Industry Production Technology Manual. At the same time, I hope that those engaged in the research and production of polysilicon can share knowledge more extensively to improve together. I have been considering the methods for treating chlorosilane waste liquid in the polysilicon production process, as well as issues related to controlling the B/P content, resistivity, and minority carrier lifetime in polysilicon. That is, how to address the problems of flammability, explosiveness, and clogging associated with the current use of lime milk in treating chlorosilane wastewater ； How to enable arbitrary control over the B:P ratio in polysilicon during its production, thereby effectively addressing the issues of removing P and B from polysilicon. Questions such as whether there is a critical value for the resistivity depending on the B:P ratio – I hope those who happen to be reading this can offer some guidance; thank you very much!
