A method is provided for selectively forming a Si-containing film on a substrate in an interrupted deposition process. The method includes providing a substrate containing a growth surface and a non-growth surface, and selectively forming the Si-containing film on the growth surface by exposing the substrate to HX gas while simultaneously exposing the substrate to a pulse of chlorinated silane gas. The Si-containing film can be a Si film or a SiGe film that is selectively formed on a Si or SiGe growth surface but not on an oxide, nitride, or oxynitride non-growth surface.
