METHOD OF DEPOSITING A SILICON GERMANIUM TIN LAYER ON A SUBSTRATE

摘要

Methods of depositing silicon germanium tin (SiGeSn) layer on a substrate are disclosed herein. In some embodiments, a method may include co-flowing a silicon source, a germanium source, and a tin source comprising a tin halide to a process chamber at a temperature of about 450 degrees Celsius or below and a pressure of about 100 Torr or below to deposit the SiGeSn layer on a first surface of the substrate. In some embodiments, the tin halide comprises tin tetrachloride (SnCl4).
