| Application | Silicon tetrafluoride is used in ion-implantation processes and as a precursor to fluorinated silica via plasma-assisted CVD. Mixtures of SiF4-SiH4-H2 have recently been used to deposit polycrystalline silicon thin films via remote plasma chemical vapor deposition (RPCVD).1,2 Such fluorinated thin films show visible photoluminescence (PL) at room temperature.3 |
