Description Silicon Iodide is the iodide of silicon. It is a precursor to silicon amide. It is also applied in the manufacture and etching of silicon in microelectronics. Selective area regrowth of silicon-doped GaAs has been successfully achieved by chemical beam epitaxy (CBE) on dry etched trench structures. Silicon tetraiodide is useful for the above process in abrupt to manipulate metal-semiconductor field effect transistor (MESFET) and heterostructure field effect transistor (HFET). Silicon iodide can also be reduced as the source to form pure silicon and hydrogen iodide.
Uses Silicon(IV) iodide is used as a precursor to prepare silicon amides. It finds application in the manufacture and etching of silicon in microelectronics.
