Silicon tetraiodide applies for the manufacturing and etching of silicon wafers used in microfabrication of electronic related components. This product has been used for the syntheses of Tetrakis(dialkylamino)silanes. SiI4 was proposed as a potential precursor for the deposition of Si-based films by CVD. SiI4 is advantageous, as it is a simple Si-contaning precursor which can be used in thermally or UV-assisted CVD deposition processes. SiI4 has a simple structure and does not require laborious synthetic procedures. Tetraiodosilane also provides high film growth rates and low minimum film deposition temperatures. See link below
