'''三溴甲硅烷'''是一种[[无机化合物]]，由[[硅]]、[[氢]]和[[溴]]组成。在高温下，它会分解成硅，是[[半导体]]工业生产超纯硅中[[三氯甲硅烷]]的替代。

==制备==
它可以由[[硅]]晶体和气态[[溴化氢]]在高温下反应而成。<ref>{{cite journal | author = Schumb WC, Young RC | title = A study of the reaction of hydrogen bromide with silicon | journal = Journal of the American Chemical Society | date = April 1930 | volume = 52 | issue = 4 | pages = 1464–1469 | doi = 10.1021/ja01367a025 }}</ref> 这个反应在1857年三溴甲硅烷首次合成时，就被[[弗里德里希·维勒]]和{{link-de|Heinrich Buff}}描述了。<ref name="J_L_Ann_Chem1857_104_94">{{Literatur| Autor=H.
