Title: Innovations by Yuepeng Wan in Polysilicon Production
Introduction
Yuepeng Wan is an accomplished inventor based in Nashua, NH, with a focus on advancements in polysilicon production. He holds a total of six patents, showcasing his expertise and innovative contributions to the field of chemical vapor deposition (CVD).
Latest Patents
One of his latest patents is titled "Increased polysilicon deposition in a CVD reactor." This invention presents a method and process for producing bulk polysilicon by replacing conventional silicon 'slim rods' with shaped silicon filaments that have larger surface areas. These filaments, which can take the form of tubes or ribbons, allow for a higher production rate without altering the reactor size or increasing the number and length of the filaments. The method involves decomposing silicon-containing gases, such as chlorosilane or silane, to form silicon deposits on the hot surfaces of the filaments.
Another significant patent is "Method of making large surface area filaments for the production of polysilicon in a CVD reactor." This method details the process of melting silicon and growing filaments from the melted silicon using an Edge-defined, Film-fed Growth (EFG) method. The filaments produced can have various cross-sectional shapes and can be doped with elements from groups 3 and 5 of the Periodic Table, enhancing their electrical properties.
