Boron11 Trichloride
常溫常壓下三氯化硼11(B11Cl3)為無色發(fā)煙氣體,可燃,有刺激性、酸性氣味,遇水分解生成氯化氫和硼酸,并放出大量熱量,在濕空氣中因水解而生成煙霧,在醇中分解為鹽酸和硼酸酯。三氯化硼11反應能力較強,能形成多種配位化合物,三氯化硼加熱能和玻璃、陶瓷起反應,也能和許多有機物反應形成各種有機硼化合物。高純三氯化硼11主要用于(硅)半導體器件制造工藝中的擴散摻雜,在高溫下,經過分解生成硼雜質向硅中擴散,形成P型半導體,也可用于Al、MoSi2、TaSi2、TiSi2、WSi等材料的干法蝕刻。
At normal temperature and pressure, boron trichloride(BCl3) is colorless smoke gas, which is flammable, pungent, acidic odor. Boron trichloride decomposes into hydrochloric acid and boric acid and releases a lot of heat encountering with water, it generates smoke in wet air because of hydrolysis, and BCl3decomposes into hydrochloric acid and boric acid ester in alcohol. Boron trichloride has a strong reaction ability and can form a variety of coordination compounds. Boron trichloride can react with glass and ceramic when heated, and it also reacts with many organic compounds to form a variety of organoboron compounds. High purity boron11 trichloride is mainly used for diffusion doping in the manufacturing process of (silicon) semiconductor devices. Boron impurities are generated through decomposition of BCl3and diffuse toward silicon to form p-type semiconductor at high temperature. BCl3 can also be used for dry etching of Al, MoSi2, TaSi2, TiSi2, WSi and other materials.
